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. servers: - url: https://partner-api.marko.fr/v1 security: - BearerAuth: [] externalDocs: description: Download the matching Postman collection. url: /v1/postman.json paths: /operations/{operation_id}: get: tags: -
