# Update membership

> Toggle domain auto-join for an account

`PATCH /api/v2/accounts/{customerId}/membership`

Updates the membership access settings for an account. Requires the `ADMIN` role and a registered `customerDomain` to enable domain auto-join. Top-level organizations default to enabled and child accounts default to disabled; this operation explicitly overrides that default.

## Request

```bash curl theme={null}
curl -X PATCH https://api.interchange.io/api/v2/accounts/200/membership \
  -H "Authorization: Bearer $SCOPE3_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "allowDomainAutoJoin": true
  }'
```

## Parameters

| Field                 | Type    | Required | Notes                                                                                                                              |
| --------------------- | ------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------- |
| `customerId`          | string  | Yes      | Path parameter. ID of the account to update                                                                                        |
| `allowDomainAutoJoin` | boolean | Yes      | When true, users with a verified matching-domain email join as members without admin approval. Requires `customerDomain` to be set |

## Response

```json theme={null}
{
  "customerId": 200,
  "allowDomainAutoJoin": true
}
```

| Field                 | Type    | Notes                     |
| --------------------- | ------- | ------------------------- |
| `customerId`          | integer | Account ID                |
| `allowDomainAutoJoin` | boolean | The setting now in effect |

## Errors

* `400 VALIDATION_ERROR` — enabling auto-join without a registered `customerDomain`.
* `401 UNAUTHORIZED` — caller is not an `ADMIN`.
