Understand Rate Limits & Errors

Interpret authorization, permission, not-found, conflict, validation, rate-limit, and server errors.

Overview

401 Unauthorized: Missing, invalid, wrong-workspace, or revoked credential.

403 Forbidden: Key lacks scope or resource access.

404 Not Found: Wrong endpoint or resource ID.

409 Conflict: Duplicate or conflicting state.

422 Validation: Missing or incorrectly formatted field.

429 Rate Limit: Slow down and apply backoff.

5xx Server Error: Retry safely with backoff and idempotency.

Who should use it

Authorized developers and technical workspace users.

Before you begin

  • Use a server-side integration environment.
  • Create separate test and production credentials.
  • Use HTTPS and least privilege.
  • Never expose a key or webhook secret in client-side code.

Security, privacy, consent, cost and provider notes

  • Use only data the business is authorized to process.
