WSO2 ESB API configuration to send same post request to different Rest services - wso2-esb

Question

I need to send a post request to different REST services, below is the complete requirement.
I am using REST API configuration of WSO2 ESB
First I need to post a request to one service and based on successful posting then need to post this same to another service. But I need to obtain the response from first service and send it to fronend. But I do not need to obtain the response from second service.
Please find the API configuration below and help me.

Your synapse configuration does not match your statement. You have to preserve the original message using enrich mediator and then make use the call mediator for your first endpoint invocation.
Then based on the results, you send the response back to your client and do the send call by reloading the message from the preservation.
