hash the input value and send to the backend in headers

[annapurnakondet]

Hi all,

I am looking for a sceanrio, where json payload from the request has a field name MessageContent and this value should be hashed in apigee. This hashed value should be sent to the backend in header.

This scenario is just to identify whether the message is tampered in the middle i.e from apigee to backend.

Here we will be comparing the data that is received in apigee with the data that is recieved at the target server.

please help me in how to achieve this.

Thanks in advance.
