Une relance avec la même clé d'idempotence rejoue la première réponse; une nouvelle intention échoue si le document est déjà rattaché. **Scope requis :** `documents:write`. [Scopes et délégation](/scopes-and-delegation). **Idempotence :** header `Idempotency-Key` obligatoire. Pour reprendre la même mutation, réutiliser la même clé et le même contenu.

Authentication flow for partner integrations: 1. Generate an API key from the MARKO entity admin API section. 2. Keep the raw API secret server-side and use it only to sign `POST /v1/auth/token`. 3. Build the canonical message `MARKO-EXTERNAL-API-TOKEN-V1\n{key_id}\n{timestamp}\n{nonce}`. 4. Sign that message with HMAC-SHA256 and send the hex signature with `key_id`, `timestamp` and `nonce`. 5. Use the returned short-lived bearer on business endpoints as `Authorization: Bearer `. The raw API secret must never be sent on business endpoints. This public contract intentionally excludes beta endpoints. Référence enrichie pour les développeurs et les assistants IA.
