Hi,
Does the callback function works with HTTPS ? I get callbacks on a regular HTTP URL but when i try to use an HTTPS URL (https://qnxqxmz0d3.execute-api.eu-west- ... ecomdesign) it doesn't work and I get a "KO" on the callback simulator but without more details to debug.
When i try my HTTPS URL in postman to simulate a POST similar than the one on HTTP it works.
Where is the problem please ?
