Just an update. The integration was getting timed out since the data was not present in the target system. My bad😑

I dont think there is means to call a post method from the script task in a process model. Get method can be called like that. Not sure on post

To check the response time difference and other possible issues, try to call integration object in script task and compare.

In JSON, angular brackets indicate a list. In Appian, we use curly brackets for lists. The functions toJson() and fromJson() convert to/from JSON to Appian.

I am not sure why you create JSON text in an expression, store it to a PV, and forward it into the integration to define the body. I suggest to create a map using a!map() instead. Pass it to the PV and the integration and let Appian automatically convert it into JSON when calling the API.

Only use JSON only to talk to the outside world, and convert to/from Appian maps directly at the borders.

We dont have that option enabled in our environment.

This is an example json which we will get it from the expression rule. I am a little skeptical on these [] braces since appian does not accept these. Will these be the reason for causing such error?

{
  "firstName":"",
  "lastName":"",
  "address":[]
}

This is a bit confusing ... and I see quite a few spots for making mistakes.

Did you try to enable HTTP logging in the integration and check the log files to see what is going on?

Yep. They are the same. It has 2 parameters which are embedded into the headers of the end point.

While testing from the integration, I am using the json body directly in rule input. While trying from process model, I am using an expression rule to construct the json and having it converted into json using a!tojson inside the expression. Then I am storing it in a pv and passing that pv as rule input into the integration object.

Not without any details.

My first question would be: "Do you use the exact same parameters when testing and in the process?"
