The org_id goes into the provider's metadata, which is the whole reason an event arriving eight hours later can be resolved to a tenant without a lookup table anybody has to keep in sync. See resolve_org.

Headers

  • Idempotency-Keystring

    A unique key of your choosing, so this request can be retried safely. The first request with a given key executes; every replay returns that first response unchanged, with Idempotent-Replay: true set.

    Generate one key per action, not per session - reusing a key with a different body is refused with 422 rather than silently replaying the wrong answer. Keys are remembered for 24 hours. A request that failed releases its key, so a retry after fixing the payload runs normally.

    X-API-Version

    The dated version of the API contract that served this response, e.g. 2026-09-03. Pin against it; it changes only when a response shape changes incompatibly.

  • 422Validation error

    The shared error envelope, served as application/problem+json with error.code set to validation_error. Its details name each field that failed and why.

Example request

curl
curl -X POST "https://api.integrable.cloud/api/billing/checkout" \
  -H "Authorization: Bearer $INTEGRABLE_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{
    "tier": "string"
  }'

Set INTEGRABLE_API_KEY first. The same call from the TypeScript or Python SDK takes the same fields.

Errors

Failures use one envelope on every endpoint, described in Retries, versioning and limits. The codes you are most likely to meet here:

  • validation_error · 422The payload was well-formed JSON but failed schema validation.
  • unauthenticated · 401The request carried no API key, or one the API could not verify.
  • forbidden · 403The key is valid, but it is not allowed to do this — either the scope is missing or the resource belongs to another workspace.
  • idempotency_key_reused · 422This `Idempotency-Key` was used before, for a request with a different body.
  • rate_limited · 429Too many requests in the current window. The limit is per workspace, and some endpoints add a per-bot limit on top.
