# Check transaction status

POST https://api.haloinvest.ng/api/banking/core-transactions/check-transaction-status
Content-Type: application/json

Returns the outcome of a transfer or debit your business sent through this API. Send the reference you used, or for debit-user-account the `debit_reference` or `credit_reference` Halo returned. Only your own references are found; any other reference answers 404. If the outcome is still unknown and the transfer is at least 3 minutes old, Halo asks the bank before answering; before that it answers `pending` without asking.

`status` is `success`, `failed` or `pending`. `amount` is in kobo. While the status is `pending`, keep checking and do not send the transfer again.

Reference: https://docs.haloinvest.ng/api-reference/transfers-and-debits/check-transaction-status

## Authentication

- `Authorization` header (bearer token, required) — Your Halo partner API key, sent as `Authorization: Bearer <key>`.

## Request

### Body (application/json)

This endpoint expects an object.

- `RetrievalReference` (string, required) — The reference of the transfer or debit, at most 64 characters. For debit-user-account, use the debit_reference or credit_reference it returned.

## Response

### 200

The recorded outcome.

- `status` (boolean, required) — True on success, false otherwise.
- `message` (EnvelopeMessage, required) — A short message. On a 422 validation failure it is an object of field names to error lists.
- `status_code` (integer, required) — The HTTP status code.
- `data` (any, optional) — The result. Left out on most errors.

## Errors

### 401 Unauthorized Error

The API key is missing or not recognised, or your business is switched off.

- `error` (UnauthorizedErrorError, optional)

### 404 Not Found Error

Your business sent no transfer with this reference.

- `status` (boolean, required) — True on success, false otherwise.
- `message` (EnvelopeMessage, required) — A short message. On a 422 validation failure it is an object of field names to error lists.
- `status_code` (integer, required) — The HTTP status code.
- `data` (any, optional) — The result. Left out on most errors.

### 422 Unprocessable Entity Error

The request failed validation. `message` lists the errors by field.

- `status` (boolean, required) — True on success, false otherwise.
- `message` (EnvelopeMessage, required) — A short message. On a 422 validation failure it is an object of field names to error lists.
- `status_code` (integer, required) — The HTTP status code.
- `data` (any, optional) — The result. Left out on most errors.

### 429 Too Many Requests Error

Too many requests. Wait and try again.

- `status` (boolean, required) — True on success, false otherwise.
- `message` (EnvelopeMessage, required) — A short message. On a 422 validation failure it is an object of field names to error lists.
- `status_code` (integer, required) — The HTTP status code.
- `data` (any, optional) — The result. Left out on most errors.

## Types

### EnvelopeMessage

A short message. On a 422 validation failure it is an object of field names to error lists.

- string
- map from string to list of string

### UnauthorizedErrorError
