Returns `manifest: null` / `published: false` when the template exists but has no published version (distinct from a 404). ## OpenAPI ````yaml /openapi.yaml get /v1/templates/{slug} 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. 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: Templates description: Create, list, fetch, republish, delete templates and enqueue renders. - name: Renders description: Poll render status, download PDFs, manage shares, email, and engagement. - name: Signatures description: >- Send rendered PDFs out for digital signatures via the signature service and track status. - name: Webhooks description: Inbound webhook receivers (HMAC-authenticated, not bearer-authed). - name: Embed description: Embed session minting, catalogs, builder templates, form submission. - name: Admin description: Org provisioning (deployment admin key only). - name: System description: Health and status. paths: /v1/templates/{slug}: parameters: - $ref: '#/components/parameters/TemplateSlug' get: tags: - Templates summary: Get a template description: > Fetch a single template's metadata, its published variable manifest, and the auto-generated JSON Schema for client-side validation.
