To use an HTTPS endpoint from an integration flow, you can use the Open Connectors capability within SAP Integration Suite. Open Connectors is a feature that allows you to connect to over 160 third-party applications using standardized and normalized APIs. You can use the HTTP client connector to make HTTP or HTTPS requests to any endpoint that supports these protocols. You can configure the HTTP client connector with various parameters, such as URL, method, headers, query parameters, body, and authentication.
