Import Payments API - Timeout (Long Running Transactions)

Using the endpoint https://api.staffology.co.uk/employers/xxx/payrun/Monthly/importpay to import the payroll we are having issues where the connection times out on large imports.

The last import we did timed out after about two minutes. Whilst the import was successful, there was of course no response to the request.

Would it be possible to have the ability to get a response with a "unique id/reference to the import" after sending the data, and then we can check on this periodically to see if completed.
