How to POST a request on Moodle using POSTMAN api tool

I want to create an API request in Postman that creates a category in Moodle. The following are the steps which I did in Moodle : 1. Enabled Web service 2. Created an External service and added core_course_create_categories function. 3. Enabled REST protocol 4. Created Token. This is my POST URL: http://localhost/test/moodle/webservice/rest/server.php?username=admin&password=Password@1&service=mycustomservice&name=CustomCategory&parent=1&idnumber=CSTM1&description=Desc Under Authorization tab, I have selected **Bearer Token** and added the Token from Moodle web service. When I send the request, I am getting **invalidtoken Invalid token - token not found** error. Can anyone please suggest a solution for this Moodle version: 3.4.8 and Postman version 7.6.0 Thanks in advance.
