La réponse contient directement marko_id. Une valeur de taxonomie inconnue est créée pour l'entité, visible immédiatement et signalée dans taxonomy_additions. Le segment généré des codes `custom__...` n'est pas prévisible : le client doit conserver le code renvoyé et le réutiliser. Une création répond 201; une mise à jour, restauration ou répétition sans changement répond 200. Les notes utilisent leur endpoint dédié; seul POST /operations/batch reste asynchrone. ## OpenAPI ````yaml https://partner-api.marko.fr/v1/openapi.json put /operations/external/{external_id} openapi: 3.1.0 info: title: MARKO External Partner API version: v1 description: >- Stable external API contract for the live environment. 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/external/{external_id}: put: tags: - operations summary: Creer ou mettre a jour une operation externe description: >- Crée ou met à jour immédiatement une opération à partir d'un identifiant partenaire stable.
