Infisical API Skill

This skill provides guidance for working with the Infisical REST API. Use it when you need to:

• Authenticate via machine identity Universal Auth
• List, get, create, update, or delete secrets
• Manage projects, environments, and members
• Work with machine identities and identity auth methods
• Handle pagination and understand rate limits
• Choose the correct API version and region

Guiding Principles

1. Always authenticate via machine identity Universal Auth first — use the Universal Auth login endpoint to obtain a Bearer token before making other API calls
2. Use /api/v4/secrets for secret operations — v1/v2/v3 secret endpoints are deprecated
3. Use /api/v1/projects, not /api/v1/workspace — workspace endpoints are deprecated
4. Pagination uses offset/limit — default limit is 20, maximum is 100
5. Region selection — US region: us.infisical.com, EU region: eu.infisical.com
6. Service tokens are deprecated — use machine identities instead
7. Rate limits apply to cloud only — self-hosted deployments have no rate limits; free tier: 200 reads/min, pro tier: 350 reads/min

Reference Files

• Authentication — Universal Auth login, auth endpoints, token patterns, deprecated service tokens
• Secrets Endpoints — CRUD operations on secrets using /api/v4/secrets
• Projects and Identities — project management, environments, members, identities, groups, folders
• Pagination and Rate Limits — offset/limit pagination, cloud rate limits, content-type requirements

Quick Start

1. Authenticate with Universal Auth

curl -X POST https://us.infisical.com/api/v1/auth/universal-auth/login \
  -H "Content-Type: application/json" \
  -d '{
    "clientId": "YOUR_CLIENT_ID",
    "clientSecret": "YOUR_CLIENT_SECRET"
  }'

Response:

{
  "accessToken": "eyJ...",
  "expiresIn": 3600,
  "accessTokenMaxTTL": 86400,
  "tokenType": "Bearer"
}

2. Use the Token for Subsequent Requests

curl -X GET 'https://us.infisical.com/api/v4/secrets?projectId=PROJECT_ID&environment=dev' \
  -H "Authorization: Bearer eyJ..."

Common Workflows

List All Secrets in a Project

curl -X GET 'https://us.infisical.com/api/v4/secrets?projectId=PROJECT_ID&environment=dev&offset=0&limit=20' \
  -H "Authorization: Bearer TOKEN"

Create a New Secret

curl -X POST 'https://us.infisical.com/api/v4/secrets/MY_SECRET' \
  -H "Authorization: Bearer TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "projectId": "PROJECT_ID",
    "environment": "dev",
    "secretPath": "/",
    "secretValue": "super-secret-value",
    "type": "shared"
  }'

Get a Specific Secret

curl -X GET 'https://us.infisical.com/api/v4/secrets/MY_SECRET?projectId=PROJECT_ID&environment=dev&secretPath=/' \
  -H "Authorization: Bearer TOKEN"

Update a Secret

curl -X PATCH 'https://us.infisical.com/api/v4/secrets/MY_SECRET' \
  -H "Authorization: Bearer TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "projectId": "PROJECT_ID",
    "environment": "dev",
    "secretPath": "/",
    "secretValue": "new-value"
  }'

Delete a Secret

curl -X DELETE 'https://us.infisical.com/api/v4/secrets/MY_SECRET?projectId=PROJECT_ID&environment=dev&secretPath=/' \
  -H "Authorization: Bearer TOKEN"

Important Notes

• All requests must include Content-Type: application/json header
• Tokens expire after expiresIn seconds; implement refresh logic for long-running operations
• For self-hosted deployments, replace us.infisical.com with your custom domain
• Secret operations support multiple auth types (AWS, Azure, GCP, Kubernetes, OIDC, JWT, LDAP)
• Use viewSecretValue=true when listing secrets if you need to see actual values
• The recursive parameter on list secrets endpoint includes secrets in all subdirectories
