The remaining recipients stay in the queue. It resumes on its own when capacity returns (purchase of extra active contacts, month turn or a higher limit); this route tries to resume right away. `updated: false` means there is still no capacity — it is not an error. A campaign in any other state returns 404. ## OpenAPI ````yaml /api-reference/openapi.en.yaml post /campaigns/{id}/retry-active-contacts-limit openapi: 3.0.3 info: title: Connecta DESK Public API version: 1.0.0 description: >- Public API of Connecta DESK, available at `/api/v1`. Access uses a token generated in the tokens module. Each token has permissions per **module × method**, and every list read is paginated. ## Authentication ``` Authorization: Bearer sk_live_a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6 ``` The token belongs to a **company**, not to a user. The company used is always the token's company, so sending `companyId` in the body has no effect. A missing, invalid, revoked or expired token gets the same `401` response. ## Order of checks 1. **token** → `401` 2. **active company** → `403` 3. **API enabled on the plan** → `403 ERR_API_NOT_ENABLED` (does not apply to on-premise) 4. **company rate limit** → `429` 5. **token permission** → `403 ERR_API_FORBIDDEN_SCOPE` ## User ids Every user id in the API is the user's id **in this company**, the same one `GET /users` returns. This applies to what the API returns (`user.id`, `assignedTo.id`, `userCreated.id`) and to what it accepts (`userId`, `userIds`, `assignedToUserId` and the `{id}` in user routes). The same person can work in several companies, with a different name and profile in each one, and has a different id in each company. An id that does not belong to this company returns `404`, with the same message as an id that does not exist. ## Pagination Every list `GET` is paginated. The `meta` contains only `page`, `perPage` and `hasMore`, without the total number of records. To go through everything, keep advancing `page` while `hasMore` is `true`. ## Idempotency Optional on `POST`/`PUT`, through the `Idempotency-Key` header. If you repeat the call with the same key and the same body, you get the stored response (with `Idempotent-Replay: true`). With the same key and a different body, the response is `409`. servers: - url: https://api.connectadesk.com/api/v1 description: Production security: - apiToken: [] tags: - name: contacts description: Contact records, extra fields and marketing source. - name: tickets x-displayName: Tickets description: Opening, transferring, closing and wrap-up of tickets. - name: messages description: Asynchronous sending and reading of messages. - name: tags description: Tags and their link to tickets. - name: queues description: Service queues and their agents. - name: wrapups description: Wrap-up types. - name: users description: Agents and administrators. - name: schedules description: Scheduled messages. - name: quick-messages description: Quick replies. - name: campaigns description: Bulk sending. - name: crm description: Boards, stages, cards and metrics. - name: channels description: Channels (read only). - name: reports description: Reports and dashboards. - name: products description: Product catalog, categories and sales performance. - name: custom-fields description: Custom fields for contacts and cards, plus company-wide global variables. - name: profiles description: Company permission profiles (read only). - name: webchat description: >- Native webchat from your own system: open a visitor session, send and read messages.
