# List campaign messages

Older version of campaign details, kept for existing integrations. Returns raw campaign messages plus a status breakdown. New integrations should use `GET /api/v2/campaigns/{id}/messages`.

Meta reviews it; its `status` starts as `PENDING`.\n2. **Check approval** with `GET /api/templates`. Only templates with `status: APPROVED` can be sent. If you created or edited templates directly in Meta, call `POST /templates/sync` first to copy them into Cekat.\n3. **Send to one contact** with `POST /templates/send`, or continue below to send to many.\n4. **Upload a recipient list** with `POST /api/recipients`. Contacts are imported in the background; poll `GET /api/recipients` until the list's `total_contacts` matches the number returned by the upload.\n5. **Create a campaign** with `POST /api/campaigns`, using the template's `wa_template_id` as `template_id`. Leave out `schedule_at` to send right away.\n6. **Track results** with `GET /api/campaigns` for totals and `GET /api/v2/campaigns/{id}/messages` for each recipient's delivery status and replies.\n\nEvery step needs the `inbox_id` of a connected WhatsApp inbox. Get it from `GET /api/inboxes` (the `id` of an inbox whose `type` is `whatsapp`).\n"}],"servers":[{"url":"https://api.cekat.ai","description":"Production"}],"security":[{"CekatApiKey":[]},{"BearerAuth":[]}],"components":{"securitySchemes":{"CekatApiKey":{"type":"apiKey","in":"header","name":"api_key","description":"Your business's Cekat API key, from **Settings → Developers & API** in the Cekat dashboard (https://chat.cekat.ai/developers?section=apikeys).
