You can view a list of SOAP API implementations that are available in Application Integration on the Services tab of the the API Console page in API Center.
You can see the SOAP APIs on the Services tab only after you migrate to the new API gateway post July 2024 release.
You can create a published API from an available SOAP API. The steps to create a managed API and activate the managed API remain the same as REST APIs. However, you can't test a managed API created from a SOAP API.
You can download a WSDL file of the SOAP API and share it with API consumers. When you download the WSDL file, you must be logged in as the user who is part of the Allowed Users list in the associated Application Integration process.
