Integrate Web API

Integrate Power Pages Web API into a code site's frontend. This skill orchestrates the full lifecycle: analyzing where integrations are needed, implementing API client code for each table, configuring permissions and site settings, and deploying the site.

Core Principles

• First table sequential, then parallel: The first table must be processed alone because it creates the shared powerPagesApi.ts client. Once that exists, remaining tables can be processed in parallel since each creates independent files (types, service, hooks).
• Parallelize independent agents: The table-permissions-architect and webapi-settings-architect agents are independent — invoke them in parallel rather than sequentially.
• Permissions require deployment: The .powerpages-site folder must exist before table permissions and site settings can be configured. Integration code can be written without it, but permissions cannot.
• Use TaskCreate/TaskUpdate: Track all progress throughout all phases — create the todo list upfront with all phases before starting any work.

Prerequisites:

• An existing Power Pages code site created via /power-pages:create-site
• A Dataverse data model (tables/columns) already set up via /power-pages:setup-datamodel or created manually
• The site must be deployed at least once (.powerpages-site folder must exist) for permissions setup

Workflow

1. Verify Site Exists — Locate the Power Pages project and verify prerequisites
2. Explore Integration Points — Analyze site code and data model to identify tables needing Web API integration
3. Review Integration Plan — Present findings to the user and confirm which tables to integrate
4. Implement Integrations — Use the webapi-integration agent for each table
5. Verify Integrations — Validate all expected files exist and the project builds successfully
6. Setup Permissions & Settings — Choose permissions source (upload diagram or let the architects analyze), then configure table permissions and Web API site settings with case-sensitive validated column names
7. Review & Deploy — Ask the user to deploy the site and invoke /power-pages:deploy-site if confirmed

---

Phase 1: Verify Site Exists

Goal: Locate the Power Pages project root and confirm that prerequisites are met

Actions:

1.1 Locate Project

Look for powerpages.config.json in the current directory or immediate subdirectories to find the project root.

Get-ChildItem -Path . -Filter "powerpages.config.json" -Recurse -Depth 1

If not found: Tell the user to create a site first with /power-pages:create-site.

1.2 Read Existing Config

Read powerpages.config.json to get the site name:

Get-Content "<PROJECT_ROOT>/powerpages.config.json" | ConvertFrom-Json

1.3 Detect Framework

Read package.json to determine the framework (React, Vue, Angular, or Astro). See ${CLAUDE_PLUGIN_ROOT}/references/framework-conventions.md for the full framework detection mapping.

1.4 Check for Data Model

Look for .datamodel-manifest.json to discover available tables:

**/.datamodel-manifest.json

If found, read it — this is the primary source for table discovery.

1.5 Check Deployment Status

Look for the .powerpages-site folder:

**/.powerpages-site

If not found: Warn the user that the permissions phase (Phase 5) will require deployment first. The integration code (Phases 2–4) can still proceed.

Output: Confirmed project root, framework, data model availability, and deployment status

---

Phase 2: Explore Integration Points

Goal: Analyze the site code and data model to identify all tables needing Web API integration

Actions:

Use the Explore agent (via Task tool with agent_type: "explore") to analyze the site code and data model. The Explore agent should answer these questions:

2.1 Discover Tables

Ask the Explore agent to identify all Dataverse tables that need Web API integration by examining:

• .datamodel-manifest.json — List of tables and their columns
• src/**/*.{ts,tsx,js,jsx,vue,astro} — Source code files that reference table data, mock data, or placeholder API calls
• Existing /_api/ fetch patterns in the code
• TypeScript interfaces or types that map to Dataverse table schemas
• Component files that display or manipulate data from Dataverse tables
• Mock data files or hardcoded arrays that should be replaced with API calls
• TODO or FIXME comments mentioning API integration

Prompt for the Explore agent:

"Analyze this Power Pages code site and identify all Dataverse tables that need Web API integration. Check .datamodel-manifest.json for the data model, then search the source code for: mock data arrays, hardcoded data, placeholder fetch calls to /_api/, TypeScript interfaces matching Dataverse column patterns (publisher prefix like cr*_), TODO/FIXME comments about API integration, and components that display table data. For each table found, report: the table logical name, the entity set name (plural), which source files reference it, what operations are needed (read/create/update/delete), and whether an existing API client or service already exists in src/shared/ or src/services/. Also check if src/shared/powerPagesApi.ts already exists."

2.2 Identify Existing Integration Code

The Explore agent should also report:

• Whether src/shared/powerPagesApi.ts (or equivalent API client) already exists
• Which tables already have service files in src/shared/services/ or src/services/
• Which tables already have type definitions in src/types/
• Any framework-specific hooks/composables already created

This avoids duplicating work that was already done.

2.3 Compile Integration Manifest

From the Explore agent's findings, compile a list of tables needing integration:

Table	Logical Name	Entity Set	Operations	Files Referencing	Existing Service
Products	cr4fc_product	cr4fc_products	CRUD	ProductList.tsx, ProductCard.tsx	None
Categories	cr4fc_category	cr4fc_categories	Read	CategoryFilter.tsx	None

Output: Complete integration manifest listing all tables, their operations, referencing files, and existing service status

---

Phase 3: Review Integration Plan

Goal: Present the integration manifest to the user and confirm which tables to integrate

Actions:

3.1 Present Findings

Show the user:

1. The tables that were identified for Web API integration
2. For each table: which files reference it, what operations are needed
3. Whether a shared API client already exists or needs to be created
4. Any tables that were skipped (already have services)

3.2 Confirm Tables

Use AskUserQuestion to confirm:

Question	Options
I found the following tables that need Web API integration: [list tables]. Which tables should I integrate?	All of them (Recommended), Let me select specific tables, I need to add more tables

If the user selects specific tables or adds more, update the integration manifest accordingly.

Output: User-confirmed list of tables to integrate

---

Phase 4: Implement Integrations

Goal: Create Web API integration code for each confirmed table using the webapi-integration agent

Actions:

4.1 Invoke Agent Per Table

For each table, use the Task tool to invoke the webapi-integration agent at ${CLAUDE_PLUGIN_ROOT}/agents/webapi-integration.md:

Prompt template for the agent:

"Integrate Power Pages Web API for the [Table Display Name] table.

• Table logical name: [logical_name]
• Entity set name: [entity_set_name]
• Operations needed: [read/create/update/delete]
• Framework: [React/Vue/Angular/Astro]
• Project root: [path]
• Source files referencing this table: [list of files]
• Data model manifest path: [path to .datamodel-manifest.json if available]

Create the TypeScript types, CRUD service layer, and framework-specific hooks/composables. Replace any mock data or placeholder API calls in the referencing source files with the new service."

4.2 Process First Table, Then Parallelize Remaining

The first table must be processed alone — it creates the shared powerPagesApi.ts client that all other tables depend on. After the first table completes and the shared client exists:

• Verify the shared API client was created at src/shared/powerPagesApi.ts
• Then invoke all remaining tables in parallel using multiple Task calls — each table creates independent files (its own types in src/types/, service in src/shared/services/, and hook/composable), so there are no conflicts

If there is only one table, this step is simply sequential.

4.3 Verify Each Integration

After each agent completes (or after all parallel agents complete), verify the output:

• Check that the expected files were created (types, service, hook/composable)
• Confirm the shared API client exists after the first table is processed
• Note any issues reported by the agent

4.4 Git Commit

After all integrations are complete, stage and commit:

git add -A
git commit -m "Add Web API integration for [table names]"

Output: Integration code created for all confirmed tables, verified and committed

---

Phase 5: Verify Integrations

Goal: Validate that all expected integration files exist, imports are correct, and the project builds successfully

Actions:

5.1 Verify File Inventory

For each integrated table, confirm the following files exist:

• Type definition in src/types/ (e.g., src/types/product.ts)
• Service file in src/shared/services/ or src/services/ (e.g., productService.ts)
• Framework-specific hook/composable (e.g., src/shared/hooks/useProducts.ts for React, src/composables/useProducts.ts for Vue)

Also verify:

• Shared API client at src/shared/powerPagesApi.ts exists
• Each service file references /_api/ endpoints
• Each service file imports from the shared API client

5.2 Verify Build

Run the project build to catch any import errors, type errors, or missing dependencies:

npm run build

If the build fails, fix the issues before proceeding. Common issues:

• Missing imports between generated files
• Type mismatches between service and type definitions
• Framework-specific compilation errors

5.3 Present Verification Results

Present a table summarizing the verification:

Table	Types	Service	Hook/Composable	API References
Products	src/types/product.ts	src/shared/services/productService.ts	src/shared/hooks/useProducts.ts	/_api/cr4fc_products
...	...	...	...	...

Build status: Pass / Fail (with details)

Output: All integration files verified, project builds successfully

---

Phase 6: Setup Permissions & Settings

Goal: Configure table permissions and Web API site settings for all integrated tables using the table-permissions-architect and webapi-settings-architect agents

Actions:

6.1 Check Deployment Prerequisite

Both agents require the .powerpages-site folder. If it doesn't exist:

Use AskUserQuestion:

Question	Options
The .powerpages-site folder was not found. The site needs to be deployed once before permissions and site settings can be configured. Would you like to deploy now?	Yes, deploy now (Recommended), Skip permissions for now — I'll set them up later

If "Yes, deploy now": Invoke /power-pages:deploy-site first, then resume this phase.

If "Skip": Skip to Phase 7 with a note that permissions and site settings still need to be configured.

6.2 Choose Permissions Source

Ask the user how they want to define the permissions using the AskUserQuestion tool:

Question: "How would you like to define the Web API permissions and settings for your site?"

Option	Description
Upload an existing permissions diagram	Provide an image (PNG/JPG) or Mermaid diagram of your existing permissions structure
Let the architects figure it out	The Table Permissions Architect and Web API Settings Architect will analyze your site's code, data model, and Dataverse environment, then propose permissions and settings automatically

Route to the appropriate path:

Path A: Upload Existing Permissions Diagram

If the user chooses to upload an existing diagram:

1. Ask the user to provide their permissions diagram. Supported formats:

   • Image file (PNG, JPG) — Use the Read tool to view the image and extract web roles, table permissions, CRUD flags, scopes, and site settings from it
   • Mermaid syntax — The user can paste a Mermaid flowchart diagram text directly in chat
   • Text description — A structured list of web roles, table permissions, scopes, and site settings

2. Parse the diagram into structured format:

   • Web roles: Match with existing roles from .powerpages-site/web-roles/ by name to get their UUIDs
   • Table permissions: Permission name, table logical name, web role UUID(s), scope, CRUD flags (read/create/write/delete/append/appendto), parent permission and relationship name (if Parent scope)
   • Site settings: Webapi/<table>/enabled and Webapi/<table>/fields — CRITICAL: fields must list specific column logical names, NEVER use * wildcard

3. Validate column names against Dataverse — Even when using a user-provided diagram, query Dataverse for each table's column LogicalNames and verify that every column in the Webapi/<table>/fields values uses the exact Dataverse LogicalName (case-sensitive). Correct any mismatches before creating files.

4. Cross-check with existing configuration in .powerpages-site/ to identify which permissions and site settings are new vs. already exist.

5. Generate a Mermaid flowchart from the parsed data (if the user provided an image or text) for visual confirmation.

6. Present the parsed permissions plan to the user for approval using AskUserQuestion:

   Question	Options
   Does this permissions plan look correct?	Approve and create files (Recommended), Request changes, Cancel

7. Proceed directly to section 6.4: Create Permission & Settings Files with the parsed data.

Path B: Let the Architects Figure It Out

If the user chooses to let the architects figure it out, proceed to section 6.3: Invoke Table Permissions Agent.

6.3 Invoke Table Permissions and Web API Settings Agents (in Parallel)

These two agents are independent — invoke them in parallel using two Task calls simultaneously:

Table Permissions Agent

Use the Task tool to invoke the table-permissions-architect agent at ${CLAUDE_PLUGIN_ROOT}/agents/table-permissions-architect.md:

Prompt:

"Analyze this Power Pages code site and propose table permissions. The following tables have been integrated with Web API: [list of tables integrated in Phase 4]. Check for existing web roles and table permissions. Propose a complete table permissions plan covering all integrated tables. After I approve the plan, create the web role and table permission YAML files using the deterministic scripts."

The agent will:

1. Analyze the site and propose a plan (with Mermaid diagram)
2. Present the plan via plan mode for user approval
3. After approval, create any needed web roles using create-web-role.js
4. Create all table permission files using create-table-permission.js
5. Return a summary of created files

Web API Settings Agent

Use the Task tool to invoke the webapi-settings-architect agent at ${CLAUDE_PLUGIN_ROOT}/agents/webapi-settings-architect.md:

Prompt:

"Analyze this Power Pages code site and propose Web API site settings. The following tables have been integrated with Web API: [list of tables integrated in Phase 4]. Check for existing site settings and query Dataverse for exact column LogicalNames. Propose site settings with case-sensitive validated column names. After I approve the plan, create the site setting YAML files using the deterministic scripts."

The agent will:

1. Analyze the site, query Dataverse for exact column LogicalNames
2. Cross-validate column names (case-sensitive)
3. Present the plan via plan mode for user approval
4. After approval, create all site setting files using create-site-setting.js
5. Return a summary of created files

Wait for both agents to complete before proceeding to 6.4.

6.4 Create Permission & Settings Files (Path A Only)

This section applies only to Path A (user-provided permissions diagram). For Path B, the architect agents create the files directly in section 6.3.

After parsing the user's diagram, create the YAML files using the deterministic scripts below. Do NOT write YAML files manually — always use these scripts which handle UUID generation, field ordering, formatting, and file naming automatically.

6.4.1 Create Web Roles (if needed)

If the plan requires new web roles that don't already exist, create them first (their UUIDs are needed for table permissions):

node "${CLAUDE_PLUGIN_ROOT}/skills/create-webroles/scripts/create-web-role.js" --projectRoot "<PROJECT_ROOT>" --name "<Role Name>" [--anonymous] [--authenticated]

Capture the JSON output ({ "id": "<uuid>", "filePath": "<path>" }) — use the id as the --webRoleIds value when creating table permissions.

6.4.2 Create Table Permissions

For each table permission in the plan. Process parent permissions before child permissions — children need the parent's UUID from the JSON output.

For Global/Contact/Account/Self scope:

node "${CLAUDE_PLUGIN_ROOT}/scripts/create-table-permission.js" --projectRoot "<PROJECT_ROOT>" --permissionName "<Permission Name>" --tableName "<table_logical_name>" --webRoleIds "<uuid1,uuid2>" --scope "<Global|Contact|Account|Self>" [--read] [--create] [--write] [--delete] [--append] [--appendto]

For Parent scope (requires parent permission UUID and relationship name):

node "${CLAUDE_PLUGIN_ROOT}/scripts/create-table-permission.js" --projectRoot "<PROJECT_ROOT>" --permissionName "<Permission Name>" --tableName "<table_logical_name>" --webRoleIds "<uuid1>" --scope "Parent" --parentPermissionId "<parent-uuid>" --parentRelationshipName "<relationship_name>" [--read] [--create] [--write] [--delete] [--append] [--appendto]

Each invocation outputs { "id": "<uuid>", "filePath": "<path>" }. Use the id as --parentPermissionId for child permissions.

6.4.3 Create Site Settings

For each site setting in the plan:

Enabled setting (boolean):

node "${CLAUDE_PLUGIN_ROOT}/scripts/create-site-setting.js" --projectRoot "<PROJECT_ROOT>" --name "Webapi/<table>/enabled" --value "true" --description "Enable Web API access for <table> table" --type "boolean"

Fields setting (string — use the validated column names from the diagram):

node "${CLAUDE_PLUGIN_ROOT}/scripts/create-site-setting.js" --projectRoot "<PROJECT_ROOT>" --name "Webapi/<table>/fields" --value "<comma-separated-validated-columns>" --description "Allowed fields for <table> Web API access"

Inner error setting (boolean, optional for debugging):

node "${CLAUDE_PLUGIN_ROOT}/scripts/create-site-setting.js" --projectRoot "<PROJECT_ROOT>" --name "Webapi/error/innererror" --value "true" --description "Enable detailed error messages for debugging" --type "boolean"

Important: The --value for fields settings MUST use exact Dataverse LogicalNames (case-sensitive, all lowercase). Using incorrect casing causes 403 Forbidden errors.

Lookup columns: For every lookup column, include both the LogicalName (cr87b_categoryid) AND the OData computed attribute (_cr87b_categoryid_value) in the fields value. The Power Pages Web API does a literal match — the LogicalName is needed for write operations, the _..._value form is needed for read operations ($select, $filter). Missing either form causes 403 errors.

6.5 Git Commit

Stage and commit the permission and settings files:

git add -A
git commit -m "Add table permissions and Web API site settings for [table names]"

Output: Table permissions and site settings created, verified, and committed

---

Phase 7: Review & Deploy

Goal: Present a summary of all work performed and offer deployment

Actions:

7.1 Record Skill Usage

Reference: ${CLAUDE_PLUGIN_ROOT}/references/skill-tracking-reference.md

Follow the skill tracking instructions in the reference to record this skill's usage. Use --skillName "IntegrateWebApi".

7.2 Present Summary

Present a summary of everything that was done:

Step	Status	Details
API Client	Created/Existed	src/shared/powerPagesApi.ts
Types	Created	src/types/product.ts, src/types/category.ts
Services	Created	src/shared/services/productService.ts, etc.
Hooks	Created	src/shared/hooks/useProducts.ts, etc.
Components Updated	X files	Mock data replaced with API calls
Table Permissions	Created	X permission files
Site Settings	Created	X setting files

7.3 Ask to Deploy

Use AskUserQuestion:

Question	Options
The Web API integration and permissions are ready. To make everything live, the site needs to be deployed. Would you like to deploy now?	Yes, deploy now (Recommended), No, I'll deploy later

If "Yes, deploy now": Invoke the /power-pages:deploy-site skill to deploy the site.

If "No, I'll deploy later": Acknowledge and remind:

"No problem! Remember to deploy your site using /power-pages:deploy-site when you're ready. The Web API calls will not work until the site is deployed with the new permissions."

7.4 Post-Deploy Notes

After deployment (or if skipped), remind the user:

• Test the API: Open the deployed site and verify Web API calls work in the browser's Network tab
• Check permissions: If any API call returns 403, verify table permissions and site settings are correct. The most common cause of 403 errors is column names in Webapi/<table>/fields not matching the exact Dataverse LogicalName (case-sensitive — must be all lowercase).
• Disable innererror in production: If Webapi/error/innererror was enabled for debugging, disable it before going live
• Web roles: Users must be assigned the appropriate web roles to access protected APIs

Output: Summary presented, deployment completed or deferred, post-deploy guidance provided

---

Important Notes

Throughout All Phases

• Use TaskCreate/TaskUpdate to track progress at every phase
• Ask for user confirmation at key decision points (see list below)
• First table sequential, then parallel — the first table creates the shared API client; after that, remaining tables can be processed in parallel since each creates independent files
• Commit at milestones — after integration code and after permission files
• Verify each integration — confirm expected files exist after each agent invocation

Key Decision Points (Wait for User)

1. After Phase 2: Confirm which tables to integrate
2. After Phase 3: Approve integration plan
3. At Phase 6.1: Deploy now or skip permissions (if .powerpages-site missing)
4. At Phase 6.2: Choose permissions source (upload diagram or let the architects analyze)
5. At Phase 6.3: Approve table permissions plan and Web API site settings plan (both agents run in parallel for Path B, each presents its own plan for approval)
6. At Phase 7.2: Deploy now or deploy later

Progress Tracking

Before starting Phase 1, create a task list with all phases using TaskCreate:

Task subject	activeForm	Description
Verify site exists	Verifying site prerequisites	Locate project root, detect framework, check data model and deployment status
Explore integration points	Analyzing code for integration points	Use Explore agent to discover tables, existing services, and compile integration manifest
Review integration plan	Reviewing integration plan with user	Present findings and confirm which tables to integrate
Implement integrations	Implementing Web API integrations	Invoke webapi-integration agent for first table (creates shared client), then remaining tables in parallel, verify output, git commit
Verify integrations	Verifying integrations	Validate all expected files exist, check imports and API references, run project build
Setup permissions and settings	Configuring permissions and site settings	Choose permissions source (upload diagram or architects), invoke table-permissions-architect and webapi-settings-architect agents in parallel, create YAML files with case-sensitive validated column names, git commit
Review and deploy	Reviewing summary and deploying	Present summary, ask about deployment, provide post-deploy guidance

Mark each task in_progress when starting it and completed when done via TaskUpdate. This gives the user visibility into progress and keeps the workflow deterministic.
