An AISP/ PISP calls an ASPSP to poll for events.
The ASPSP responds with an array of awaiting events encoded as signed event notifications.
Awaiting events are the events that have not been acknowledgement by the AISP/ PISP, or have been reported as errors by the AISP/ PISP.
...
An AISP/ PISP calls an ASPSP to acknowledge the event notifications that have been successfully processed.
If required, the AISP/ PISP also sends indicators of event notifications which they could not process due to an error.
The ASPSP responds positively but sends no further events.
Step 2b: Poll and Acknowledge
...
An AISP/ PISP calls an ASPSP to acknowledge the event notifications that have been successfully processed with appropriate parameters to receive more.
If required, the AISP/ PISP also sends event notifications which they could not process due to an error.
The ASPSP responds positively and responds with an array of awaiting event notifications encoded as signed event notifications.
Acknowledgement Acknowledgment by the AISP/ PISP
Recipients of event notifications must acknowledge them. This is manifested in one of two ways:
Through positive acknowledgement in that the event notification has been received and successfully processed.
Through negative acknowledgement where the event notification has been received but the AISP/ PISP encountered an error in processing.
ASPSPs can evict positively acknowledged event notifications from their stores. It is implicit that AISPs/ PISPs are responsible for retaining a record of event notifications appropriate to their needs once positively acknowledged.
...
The POST method allows the AISP/ PISP to transmit their polling parameters and event notification acknowledgements.acknowledgments
The ASPSP responds accordingly, sending event notifications as indicated by the AISPs/ PISPs polling parametersparameter
