Get payIn status
GET /api/v1/payins/{external_id}
Returns the current payIn status for your external_id.
Shop routing: when using multiple shops, you can pass shop_code in the query. If shop_code is provided, the search is limited to that shop. If shop_code is omitted, the API searches only in the merchant's default active shop. If no default active shop is configured, the API returns 422.

PayIn statuses
HTTP status responses use merchant-facing statuses. Internal processing states such as processing, waiting_api, processing_api, pay_error, and polling_expired are collapsed to pending in the REST API response.
| Status | Description |
|---|---|
| pending | Created or still in progress from the merchant point of view. |
| success | Completed successfully. |
| failed | Processing finished with an error. |
| canceled | The user canceled the operation. |
| refunded | The amount was refunded after completion. |
| expired | The time for completing the payin expired. |
Status change notifications are sent to callback_url if it was provided at creation, or to the default webhook URL.
