Ownership is resolved before the body is read, so an unowned/soft-deleted id returns `404` even with an invalid body. ## OpenAPI ````yaml /openapi.yaml patch /v1/projects/{id} openapi: 3.1.0 info: title: Craftkit API version: 1.0.0 description: | The Craftkit public REST API. Design templates with typed variables, render PDFs asynchronously, share and track them, and send them out for digital signature. ## Authentication Most endpoints authenticate with a **project API key** as a bearer token: ``` Authorization: Bearer ck_live_xxxxxxxxxxxxxxxx ``` Keys come in `ck_live_` (production) and `ck_test_` (test) flavours. The `/v1/projects*` endpoints are the one exception — they authenticate with a separate **account API key** (`ck_acct_…`) instead, scoped to every project the account owns rather than to a single project. The two credential types are strictly disjoint: a project key is rejected on `/v1/projects*` and an account key is rejected everywhere else. See [Authentication](/guides/authentication). Embed iframe surfaces use a short-lived **embed session JWT** instead, and the admin provisioning endpoint uses the deployment-wide `CRAFTKIT_ADMIN_KEY`. Inbound webhooks (`/v1/hooks/*`) are not bearer-authed — they are verified by an HMAC signature header. ## Idempotency `POST /v1/templates/{slug}/render` and `POST /v1/signatures` accept an `Idempotency-Key` request header. Retrying with the same key returns the original resource instead of creating (and, for signatures, billing) a duplicate. ## Errors Application errors use a shared envelope: ```json { "error": { "code": "invalid_request", "message": "...", "issues": { } } } ``` A small number of admin/embed endpoints return a flatter shape (`{ "error": "invalid_credentials" }`); those are documented inline. servers: - url: https://api.craftkit.dev description: Production security: - bearerApiKey: [] tags: - name: Projects description: >- Account-scoped project management and per-project key minting.

For embed partner endpoints this is the partner secret key, which is the same credential type. bearerAccountKey: type: http scheme: bearer description: | Account API key (`ck_acct_…`) presented as a bearer token. Distinct credential system from `bearerApiKey` — validated against a separate table, never against project keys or vice versa. Scoped to every project owned by the account; used **only** by the `/v1/projects*` endpoints below (each of which declares this scheme explicitly and does not inherit the document-level `bearerApiKey` default). Minted from the dashboard (**Account → API keys**) — there is no programmatic endpoint that issues an account key. ````
