Automate WhatsApp

When to use

Use this skill to build and run WhatsApp automations: workflow CRUD, graph edits, triggers, executions, function management, app integrations, and D1 database operations.

Setup

Env vars:

KAPSO_API_BASE_URL (host only, no /platform/v1)
KAPSO_API_KEY

How to

Edit a workflow graph

Fetch graph: node scripts/get-graph.js <workflow_id> (note the lock_version)
Edit the JSON (see graph rules below)
Validate: node scripts/validate-graph.js --definition-file <path>
Update: node scripts/update-graph.js <workflow_id> --expected-lock-version <n> --definition-file <path>
Re-fetch to confirm

For small edits, use edit-graph.js with --old-file and --new-file instead.

If you get a lock_version conflict: re-fetch, re-apply changes, retry with new lock_version.

Manage triggers

List: node scripts/list-triggers.js <workflow_id>
Create: node scripts/create-trigger.js <workflow_id> --trigger-type <type> --phone-number-id <id>
Toggle: node scripts/update-trigger.js --trigger-id <id> --active true|false
Delete: node scripts/delete-trigger.js --trigger-id <id>

For inbound_message triggers, first run node scripts/list-whatsapp-phone-numbers.js to get phone_number_id.

Debug executions

List: node scripts/list-executions.js <workflow_id>
Inspect: node scripts/get-execution.js <execution-id>
Get value: node scripts/get-context-value.js <execution-id> --variable-path vars.foo
Events: node scripts/list-execution-events.js <execution-id>

Create and deploy a function

Write code with handler signature (see function rules below)
Create: node scripts/create-function.js --name <name> --code-file <path>
Deploy: node scripts/deploy-function.js --function-id <id>
Verify: node scripts/get-function.js --function-id <id>

Set up agent node with app integrations

Find model: node scripts/list-provider-models.js
Find account: node scripts/list-accounts.js --app-slug <slug> (use pipedream_account_id)
Find action: node scripts/search-actions.js --query <word> --app-slug <slug> (action_id = key)
Create integration: node scripts/create-integration.js --action-id <id> --app-slug <slug> --account-id <id> --configured-props <json>
Add tools to agent node via flow_agent_app_integration_tools

Database CRUD

List tables: node scripts/list-tables.js
Query: node scripts/query-rows.js --table <name> --filters <json>
Create/update/delete with row scripts

Graph rules

Exactly one start node with id = start
Never change existing node IDs
Use {node_type}_{timestamp_ms} for new node IDs
Non-decide nodes have 0 or 1 outgoing next edge
Decide edge labels must match conditions[].label
Edge keys are source/target/label (not from/to)

For full schema details, see references/graph-contract.md.

Function rules

async function handler(request, env) {
  // Parse input
  const body = await request.json();
  // Use env.KV and env.DB as needed
  return new Response(JSON.stringify({ result: "ok" }));
}

Do NOT use export, export default, or arrow functions
Return a Response object

Execution context

Always use this structure:

vars - user-defined variables
system - system variables
context - channel data
metadata - request metadata

Scripts

Workflows

Script	Purpose
`list-workflows.js`	List workflows (metadata only)
`get-workflow.js`	Get workflow metadata
`create-workflow.js`	Create a workflow
`update-workflow-settings.js`	Update workflow settings

Graph

Script	Purpose
`get-graph.js`	Get workflow graph + lock_version
`edit-graph.js`	Patch graph via string replacement
`update-graph.js`	Replace entire graph
`validate-graph.js`	Validate graph structure locally

Triggers

Script	Purpose
`list-triggers.js`	List triggers for a workflow
`create-trigger.js`	Create a trigger
`update-trigger.js`	Enable/disable a trigger
`delete-trigger.js`	Delete a trigger
`list-whatsapp-phone-numbers.js`	List phone numbers for trigger setup

Executions

Script	Purpose
`list-executions.js`	List executions
`get-execution.js`	Get execution details
`get-context-value.js`	Read value from execution context
`update-execution-status.js`	Force execution state
`resume-execution.js`	Resume waiting execution
`list-execution-events.js`	List execution events

Functions

Script	Purpose
`list-functions.js`	List project functions
`get-function.js`	Get function details + code
`create-function.js`	Create a function
`update-function.js`	Update function code
`deploy-function.js`	Deploy function to runtime
`invoke-function.js`	Invoke function with payload
`list-function-invocations.js`	List function invocations

App integrations

Script	Purpose
`list-apps.js`	Search integration apps
`search-actions.js`	Search actions (action_id = key)
`get-action-schema.js`	Get action JSON schema
`list-accounts.js`	List connected accounts
`create-connect-token.js`	Create OAuth connect link
`configure-prop.js`	Resolve remote_options for a prop
`reload-props.js`	Reload dynamic props
`list-integrations.js`	List saved integrations
`create-integration.js`	Create an integration
`update-integration.js`	Update an integration
`delete-integration.js`	Delete an integration

Databases

Script	Purpose
`list-tables.js`	List D1 tables
`get-table.js`	Get table schema + sample rows
`query-rows.js`	Query rows with filters
`create-row.js`	Create a row
`update-row.js`	Update rows
`upsert-row.js`	Upsert a row
`delete-row.js`	Delete rows

OpenAPI

Script	Purpose
`openapi-explore.mjs`	Explore OpenAPI (search/op/schema/where)

Install deps (once):

npm i

Examples:

node scripts/openapi-explore.mjs --spec workflows search "variables"
node scripts/openapi-explore.mjs --spec workflows op getWorkflowVariables
node scripts/openapi-explore.mjs --spec platform op queryDatabaseRows

Notes

Prefer file paths over inline JSON (--definition-file, --code-file)
action_id is the same as key from search-actions
--account-id uses pipedream_account_id from list-accounts
Variable CRUD (variables-set.js, variables-delete.js) is blocked - Platform API doesn't support it
Raw SQL execution is not supported via Platform API
