Verify if the propertyType
parameter is being included in the body or query string of the request exactly as the API expects it and then check that the OAuth 2.0 authentication is working correctly within Synapse. Since it's working on Postman, there might be an issue with how the token is being used or generated in Synapse.
If you are sending the propertyType
in the body of a POST request, make sure the Content-Type
header is set correctly ( application/json
or application/x-www-form-urlencoded
)
