The document describes how to publish events to Firebase Cloud Messaging (FCM) through the Business Eventing Toolkit for SAP.
Prerequisites
Make sure that you or your administrators have completed the following prerequisites:
Enabled the Firebase Cloud Messaging API. For information about how to enable Firebase Cloud Messaging APIs, see Enabling APIs.
Configured a client key for authentication. For information about how to set up authentication in the on-premises or any cloud edition of ABAP SDK for Google Cloud, see Authentication overview.
To publish event data to Firebase Cloud Messaging, call the publish() method:
DATA:lt_dataTYPE/goog/if_ce_publisher=>tt_messages." Write logic to populate LT_DATA.lt_data=VALUE#((data='Hello World!'))./goog/cl_event_publisher=>publish_event(EXPORTINGiv_event_key='EVENT_KEY'it_data=lt_dataIMPORTINGet_output=DATA(lt_output)ev_ret_code=DATA(lv_ret_code)ev_err_text=DATA(lv_err_text)).
Replace EVENT_KEY with the event key configured for publishing events to Firebase Cloud Messaging.
To send an event as a CloudEvent, you can configure the Cloud Event Default Attribute Key
and attach this key to your Event key when configuring the target Google Cloud services. The Business Eventing Toolkit for SAP
then picks up the default attribute values for the CloudEvent.
