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: /operateurs/external/{external_id}: get: tags: - operateurs summary: Récupérer un opérateur par identifiant externe description: Résout l'identifiant stable du partenaire vers l'opérateur MARKO. operationId: operateurs_external_get parameters: - in: path name: external_id required: true schema: type: string pattern: ^[A-Za-z0-9_~-][A-Za-z0-9._:~-]{0,254}$ minLength: 1 maxLength: 255 example: CF-OPERATEUR-001 - in: header name: X-Request-ID required: false description: >- Partner-generated correlation identifier echoed in logs and error payloads. schema: type: string example: marko-operateurs-external-get responses: '200': description: Successful response content: application/json: schema: properties: name: anyOf: - type: string - type: 'null' default: null title: Name siren: anyOf: - type: string - type: 'null' default: null title: Siren type: anyOf: - description: Type d'opérateur. enum: - promoteur - marchand_de_biens - asset_manager - fonciere - entrepreneur_general title: OperateurType type: string - type: 'null' default: null id: format: uuid title: Id type: string data: additionalProperties: true title: Data type: object source_extraction: title: Source Extraction type: boolean litiges_en_cours: title: Litiges En Cours type: boolean litiges_detail: anyOf: - type: string - type: 'null' default: null title: Litiges Detail created_at: format: date-time title: Created At type: string updated_at: format: date-time title: Updated At type: string responsable_interne: anyOf: - type: string - type: 'null' default: null title: Responsable Interne reputation_gouvernance_score: anyOf: - type: number - type: 'null' default: null title: Reputation Gouvernance Score reputation_gouvernance_label: anyOf: - type: string - type: 'null' default: null title: Reputation Gouvernance Label forme_societe_mere: anyOf: - type: string - type: 'null' default: null title: Forme Societe Mere siren_mere: anyOf: - type: string - type: 'null' default: null title: Siren Mere required: - id - data - source_extraction - litiges_en_cours - created_at - updated_at title: OperateurResponse type: object example: id: aaaaaaaa-aaaa-4aaa-8aaa-aaaaaaaaaaaa name: Promoteur Demo siren: null data: {} source_extraction: false litiges_en_cours: false created_at: '2026-08-22T08:00:00Z' updated_at: '2026-08-22T08:00:00Z' '401': description: Authentication required content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' example: type: about:blank title: Unauthorized status: 401 detail: A valid bearer token is required. request_id: req_example_partner_call '403': description: Scope, route or IP restriction content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' example: type: about:blank title: Forbidden status: 403 detail: The API key does not allow this operation. request_id: req_example_partner_call '422': description: Validation failed content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' example: type: about:blank title: Unprocessable Content status: 422 detail: The request payload or parameters are invalid. request_id: req_example_partner_call '429': description: Rate limit or progressive ban headers: Retry-After: description: Cooldown in seconds before retrying the request. schema: type: string content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' example: type: about:blank title: Too Many Requests status: 429 detail: The request rate limit was exceeded. request_id: req_example_partner_call '500': description: Unexpected server error content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' example: type: about:blank title: Internal Server Error status: 500 detail: An unexpected server error occurred. request_id: req_example_partner_call deprecated: false security: - BearerAuth: [] components: schemas: ProblemDetails: type: object required: - title - status - detail properties: type: type: string default: about:blank title: type: string status: type: integer detail: type: string request_id: type: string scope: type: string route_id: type: string reason_code: type: string securitySchemes: BearerAuth: type: http scheme: bearer bearerFormat: MARKO short-lived bearer description: >- Use the `access_token` returned by `POST /v1/auth/token`.
