Step 1: Retrieving the SLD for the Destination IPS
The Source Bank ask the Source Gateway for the Destination IPS's Service Level Description
As a first step in the payment process, the Sender must select the Destination country for the payment (1). The Source Bank will then call the Source Gateway’s SLD API (2), to retrieve the SLD for the Destination IPS.
The Source Gateway will load the SLD for the Destination IPS and return this to the Source Bank.
This step is necessary so that the Source Bank’s app knows which information to ask the Sender for and can set up the screens accordingly. For example, the app needs to know what account formats or aliases are accepted and the maximum payment size that can be sent to that country.
