Lookup the Payments Resource using the x-idempotency-key. If an idempotency key is matched the Links object will be returned with the Self value populated. This will provide a pointer to the correct resource.
This is an alternative way for TPPs to obtain the response to a payment initiation operation where they did not receive any response body from the LFI (due to network error or timeout).
TPP confidential client authorization with the LFI to stage a consent.

The User's IP address if the User is currently logged in with the TPP.
An RFC4122 UID used as a correlation id.
Indicates the user-agent that the User is using.
Ensures the LFI processes the resource successfully only once per x-idempotency-key
The TPP must not change the request body while using the same x-idempotency-key, changes to the request body will not result any action on the end resource.
The OFP will treat a request as idempotent if it had received the first request with the same x-idempotency-key from the same TPP in the preceding 24 hours.
