Hi, Can you point to any API/example which will facilitate the addition of key-value (meta-data) pairs in the message sent from client? I tried to search with respect to ZAP and found that it only facilitates the type of authentication to be used. But I am not able to locate any API which add/retrieve the key value pairs.
