Need to test API in jmeter. But did not find an option for form-data.
So I tried to add with "parameter" and "Body Data", and now I am getting 400 at Response.

form-data assumes submitting a HTML Form, all the inputs need to be provided via "Name" and "Value" parameters:
If this is a multipart/form-data request - you need to tick the appropriate box
In case you need to send any files - specify them in the Files Upload tab:
If your request works fine in Postman the easiest way of replicating it in JMeter would be just recording it using JMeter's HTTP(S) Test Script Recorder
Start the HTTP(S) Test Script Recorder
Import JMeter's certificate into Postman, this way JMeter will be able to intercept and record HTTPS requests
Configure Postman to use JMeter as the proxy so the request to API would go through JMeter
Run your request in Postman
JMeter will generate HTTP Request Sampler and HTTP Header Manager
Correlate dynamic parameters if needed and replace recorded hard coded values with the relevant JMeter Variables
If the request assumes any files upload - make sure that the file(s) are placed in "bin" folder of your JMeter installation.
You should be able to run the request successfully now
