How to use callback function with plsql_rest_sender_api.call_rest_endpoint?

Yes, it is possible. I checked the “plsql_rest_sender_API.REST_Common_Callback” procedure. There was a problem with arguments. After that, I added key_ref_ and fnd_user_ arguments to use in the callback function. Now it is transferring response.

The Request

REST_Common_Callback (It will use :result, :app_msg_id, :fnd_user, :key_ref as argument to call actual callback function)

Actual Callback 

Response Table

Application Message

Hi,

I’m currently facing a similar issue. I’ve defined my own callback function to log the response in a custom table:

1PROCEDURE Response_Callback_Function(xml_ CLOB, app_msg_id_ VARCHAR2, key_ref_ VARCHAR2, fnd_user_ VARCHAR2)IS   objid_ VARCHAR2(2000);   objversion_ VARCHAR2(2000);   -- Cursor to get Correlation record obj data   CURSOR Get_Obj(app_message_id_ VARCHAR2) IS   SELECT objid, objversion   FROM c_correlation_log   WHERE app_message_id = app_message_id_;BEGIN   -- Modify Correlation Log record to add response	OPEN Get_Obj(app_msg_id_);	FETCH Get_Obj INTO objid_,objversion_;	CLOSE Get_Obj;   C_Correlation_Log_API.Write_Response_Payload__(objversion_,objid_,xml_);   @ApproveTransactionStatement(2025-01-14,Manuel Toca)	COMMIT; END Response_Callback_Function;

Here is how I’m calling this callback function in the asynchronous Rest call:

1Plsql_Rest_Sender_API.Call_Rest_Endpoint_Json(rest_service_ => 'C_Task_Status_Change',                                                      json_ => json_,                                                      message_id_ => message_id_,                                                      key_ref_ => key_ref_,                                                      fnd_user_ => 'IFSAPP',                                                      callback_func_ => 'C_Outbound_Util_API.Response_Callback_Function',                                                      http_method_  => 'POST',                                                      http_req_headers_ => http_req_headers_,                                                      sender_ => 'IFSAPP',                                                      receiver_     => 'StatusChange',                                                      message_type_ => 'APPLICATION_MESSAGE',                                                       subject_ => 'StatusChanged');

However, it doesn’t seem like it’s triggering the callback function at all; I don’t see the response logged in our custom table nor do I see that the callback execution log from the Application Messages.

Can someone let me know if I missed anything? Thanks.
