Webex guest issuer integration with widgets — Create team web api issue

Question

I am trying to create a Webex team using the following process. But not working. I had created JWT token and exchanged it for access token which I had passed in to the Authorization header in the API call. But I keep getting the error message that I mentioned below. And another fact is I can execute the same API with GET method which returns the number of teams I had.I had followed steps in the webex developer site. But I can't create the team.

Request URL: 
https://api.ciscospark.com/v1/teams
Request Method: 
POST

The following is the header that I passed to the API

Accept: application/json

Content-Type: application/json

Authorization: Bearer eyJhbGciOiJSUzI1NiJ9..VNUms24YsiwNbU_KN0Y7v1osAilq1MMiIQn6DRnyNitJAgeTLuyrwiYM0JIaox-dQxQKBp897uAj9vksg0ik2-j2MddcRmx4gsVF787uw7VpCIiZNNME346__xddvmmttna7IErBTz84hqZsnvSlmKLpus4lQs_k9I8ZHTsuPJ9FRXPry6ZAmPjDk1uWGGWFXyOSgH-VkDj9hY9Fy_6r7MKIn0YV21dxIKaZVZ6DMo1NSJM68I-90Vv-QbQY3gBeH25ZXDNDDBJg6-woMF2QPk_N8zrL8G1WPRXxGAA_lqGr_qGq65CfOwuqGikpLsRtjhWU4sYDX3xrK918W08CFw

This is the parameter I passed to the API

name=hearingteam

This is the server response {"message":"The request could not be understood by the server due to malformed syntax.","errors":[{"description":"The request could not be understood by the server due to malformed syntax."}],"trackingId":"ROUTER_5CEB64F0-FC8D-01BB-05C2-7AA62A6905C2"}

Answer 1

The API requires parameters to be passed in JSON format.

Eg : JSON.stringyfy({"name":"hearingteam"});
