API gateway compatibility mode
Talend Cloud API Designer offers an API gateway compatibility mode to help you import your definition into AWS API Gateway and Azure API Management.
When exporting your API in a gateway compatibility mode, Talend Cloud API Designer may modify your definition so it can be imported successfully into the selected gateway.
In some cases, there are no modifications but a message is displayed to inform you of the compatibility issue that you may encounter with the definition you exported.
