I am working on a requirement to send notification to specific recipients via SMS thru a REST api. Initially we were able to integrate into the said API but it was only for single recipient for which we just pass the value from the payload into the URL as parameters.
As mentioned, the setup now is to send to multiple recipients in one Proxy trigger from S4/HANA. The API would to take the parameters to contained into the BODY of the request.
Can anyone give some guidance on this?
