Request has not been completed yet. Please check back in couple of minutes

Hi Omar,
I've asked the API team about your query and they've advised this is normal behaviour with the Reckon Accounts Hosted API when the request takes longer than approximately 2.5 minutes to process (i.e. a the sent request is asking for a significant amount of data or submitting a significant amount of data). The API returns a 'Check back..' message due to the pending request timeout.

To get the request results, an additional request submitting the RequestID that was returned with the 'Check back..; response.
This secondary request is: https://api.reckon.com/RAH/v2/{retrieveid} where 'retrieveid' is the RequestId returned in the initial response. In your case this is: 8f7136c0-7130-415b-8498-4362173b1df9
If the request is still not finished when a secondary request is sent, another 'Check back..' response will be received and another secondary request specifying RequestId will need to be sent. This continues until the response data for the initial request is returned.
