## Simulate a delivery status

`POST https://whatsapp.paaltech.org/api/v1/businesses/{external_id}/sandbox/messages/{id}/status`

Test keys only. Meta reports `delivered`, `read` or `failed` for a message you sent in
the sandbox: it goes through the live path and fires `message.status`. Statuses only move
forward, as live.

Ability: `messages.send`

### Path parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `external_id` | string | yes | Your own ID for the business (Multi-SKUUL - the tenant ID). Max 191 characters. Pattern `^[A-Za-z0-9._:-]+$` |
| `id` | integer | yes | PaalChat's message ID. |

### Body

| Name | Type | Required | Description |
|---|---|---|---|
| `status` | string | yes | One of: `delivered`, `read`, `failed` |
| `error` | object | null | no | For failed - the code and message to report. |
| `error.code` | string | no |  |
| `error.message` | string | no |  |
