```

Complete a transaction that was created in a `CUSTOMER_ACTION_REQUIRED` state and needs an extra authorization step, such as a one-time password (OTP) on a mobile-money deposit. The request body is discriminated by `type`; today the only supported variant is `OTP`. A deposit needs this step when the create-transaction response comes back with status `CUSTOMER_ACTION_REQUIRED` and `meta.otpRequired` set to `true`.

**Testing in sandbox?** Submit the OTP `123456` to complete the deposit. Any other value is rejected so you can test the wrong-OTP path. See [Simulating OTP-required deposits](https://docs.afriex.com/development#simulating-otp-required-deposits) for the full sandbox flow.

### Authorizations

- **x-api-key**: Static business API key issued from the dashboard. A business can provision multiple API keys, each scoped to a configurable set of permissions (e.g. read transactions, create deposits, etc.). Permissions are chosen per key at creation time in the dashboard and may be revoked by deleting the key.

### Headers

- **x-api-version**: API version in ISO 8601 format (e.g. 2025-12-28). Defaults to latest stable.

### Path Parameters

- **transactionId**: The unique identifier of the transaction

### Body

- **type**: The authorization method. Available options: `OTP`
- **otp**: The one-time password supplied by the customer.

### Response

- **200**: Transaction authorized successfully.
