The purpose is to check the user completed the new survey or not...
Then only end user can login into market place so its better if i get the flow for the same like what things required for the same, for example
step 1 - create user through API
step 2 - call workspace (which is already created)
step 3 - call survey API to check the user is completed the survey or not
Its a example.. now to implement the same , i need end point URL , i know API presents on the portal but its not resolve my query, i need specific url to check the same then only i can work on remaining things like dependencies of that API
