Use POST method in Integration Designer (8.2)
You can source data from any REST endpoint that requires a POST method to retrieve information. With the POST method, you can encrypt sensitive information, for example, a patient's data, in the body of the request.
To send encrypted data with the POST method, enter the correct URL endpoint in the Connection details section, as shown in the following figure. Add the data to a request body by clicking Add sample request.
For more information about using the POST method, see the POST method section on Service REST form - Completing the Methods tab
