How to pass paramaters for data in HTTP request?

1

I’m trying to use HTTP requests to authenticate my users. But I’m not able to pass the parameters to the data list to send them through the body.

When I try to make a request to obtain a token, I get an error response displaying the parameter data empty: “data:[]”.

I already tried to pass these parameters via header and in the body through a formula creating a value with a JSON structure (key: value), but nothing solved my problem.

Does anyone have a suggestion to give me?

Well, I found a solution:

The syntax for Formula in Request Body is:
{"username":pageVars.credentials.username,"password":pageVars.credentials.password}

WARNING: ignore the validation message on formula console "Object property “password” is not JSON-serializable
