# Assign sender accounts

`PUT https://api.versionseven.ai/v1/campaigns/{campaign_id}/senders`

Sets the accounts that send for the campaign, replacing the current set. `account_ids` are the `id` values from [List sender accounts](https://docs.versionseven.ai/api-reference/accounts/list-accounts); send at least one.

Every account must belong to your organization (`400 INVALID_ACCOUNT` otherwise), be connected (`409 ACCOUNT_NOT_CONNECTED`, with the accounts in `details.account_ids`), and not be sending for another active campaign (`409 ACCOUNT_IN_USE`, with each account and the campaign holding it in `details.conflicts`). The response lists the assigned accounts under `enabled_accounts`, each with its `id`, `platform` and `label`.

- Required scope: `campaigns:write`

        ],
    },
)
data = response.json()
```

## Headers

## Path parameters

- `campaign_id` (string · uuid, required): ID of the campaign.

## Request body

- `account_ids` (array of strings, required): Connected account ids (the `id` from GET /v1/accounts). Replaces the current set. Each must be connected and not sending for another active campaign.

## Response

### `200`

```json
{
  "message": "string",
  "campaign_id": "550e8400-e29b-41d4-a716-446655440000",
  "enabled_accounts": [
    {}
  ],
  "success": true
}
```

- `message` (string, required)
- `campaign_id` (string, required)
- `enabled_accounts` (array of objects, optional)
- `success` (boolean, optional, default `true`)

## Errors

Errors share one JSON body: `success`, `error`, `message`, optional `details`, and `request_id`. For example:

```json
{
  "success": false,
  "error": "UNAUTHORIZED",
  "message": "Invalid or inactive API key",
  "request_id": "734d11a1-54d4-414c-9e8d-4e1ada977db4"
}
```

| Status | Code | Meaning |
| --- | --- | --- |
| 400 | `VALIDATION_ERROR` | The request didn't match the endpoint's schema: a missing or malformed field, a bad query parameter, or a value out of range. `details.errors` lists each failing field with its `field`, `message` and `type`. |
| 400 | `INVALID_ACCOUNT` | A sender account ID in the request isn't a connected account in your organization. Answered when a connected assistant assigns sender accounts to a campaign. This is a `400` rather than a `404` for the same reason as `INVALID_LEAD`. |
| 401 | `UNAUTHORIZED` | The `Authorization` header is missing or malformed, or the API key is unknown or has been deactivated. |
| 401 | `API_KEY_EXPIRED` | The API key is past its expiry date. Create a new key in the Victoria AI app. |
| 403 | `INSUFFICIENT_SCOPE` | The API key doesn't have the scope this endpoint requires, such as `leads:write`. |
| 403 | `ORGANIZATION_DEACTIVATED` | The organization that owns this API key has been deactivated. |
| 404 | `CAMPAIGN_NOT_FOUND` | No campaign with this ID exists in your organization. |
| 404 | `NOT_FOUND` | No endpoint matches the path. A resource ID in the path that isn't a valid UUID also answers `NOT_FOUND`. |
| 409 | `ACCOUNT_NOT_CONNECTED` | A sender account being assigned to the campaign has disconnected. Reconnect it in the Victoria AI app or with a [reconnect link](https://docs.versionseven.ai/api-reference/accounts/create-connect-link) first. `details.account_ids` lists the accounts. |
| 409 | `ACCOUNT_IN_USE` | A sender account sends for one active campaign at a time, and one being assigned is already used by another active campaign. `details.conflicts` names each account and the campaign holding it. |
| 413 | `PAYLOAD_TOO_LARGE` | The request body is larger than 1 MB. |
| 429 | `RATE_LIMITED` | Too many requests for this API key: more than 100 a minute to one endpoint, or 600 a minute in total. Retry after the number of seconds in the `Retry-After` header. See [Rate limits](https://docs.versionseven.ai/guides/rate-limits). |
| 500 | `INTERNAL_ERROR` | Something failed on our side. The response never includes internal details; quote its `request_id` when you contact support. |
| 503 | `UPSTREAM_TIMEOUT` | A service the API depends on timed out. The request is safe to retry. |
| 503 | `AUTH_UNAVAILABLE` | The API key couldn't be checked because the authentication service was unavailable. The request is safe to retry. |

## Response headers

| Header | Description |
| --- | --- |
| `X-Request-ID` | Correlation ID for the request, also returned as `request_id` in error bodies. Send your own `X-Request-ID`, up to 128 letters, digits, `.`, `_`, `:` or `-`, and it's used instead. |
| `RateLimit-Limit` | Requests allowed to this endpoint per minute. |
| `RateLimit-Remaining` | Requests you can still send to this endpoint right now. |
| `RateLimit-Reset` | Seconds until the endpoint's full limit is available again. |
| `Retry-After` | On a `429`: seconds to wait before retrying. |
