      send_resolved: true
      http_config:
        basic_auth:
          username: <username>
          password: <pwd>

I want to append the below JSON to the above receiver

{
   "request": {
      "entry": {
         "u_description": " description2",
         "u_work_notes": " work notes",
         "u_assignment_group": "APM Team",
         "u_impact": "2",

AFAIK, alertmanager webhook JSON is fixed.  If you want to send something else, then you have to write your own webhook receiver which receives the request from alertmanager and then reformats it and resends it to the upstream service.

Have a look at other projects which already do this, e.g. prom2teams

Sorry for asking multiple times, can I have an example of how to pass the payload in the webhook for the  post request or any POST-WEBHOOK JSON example

Yes: the source code for prom2teams is on github, and you can follow that.

You cannot change the payload in the webhook *as it is sent by Alertmanager*. Hence you need to run a piece of software which will receive the alertmanager webhook, change the contents, and then resend it to the final destination.  Just like prom2teams does.
