You can configure one or more authentication and authorization types for managed APIs that invoke a Cloud Application Integration process that uses basic authentication. You can't configure authentication for managed APIs that invoke a Cloud Application Integration process with an anonymous authentication or for custom APIs.
You can configure the following types of authentication and authorization:
•Basic. The user groups and users that are allowed access to the process in Informatica Cloud Application Integration can invoke the API. To invoke the managed API, API consumers authenticate with an Informatica Intelligent Cloud Services user name and password.
•OAuth 2.0. You create an OAuth 2.0 client in API Manager. API consumers use the client credentials to generate an OAuth 2.0 authorization token that they use to invoke the API. API Manager supports the client credentials grant type for OAuth 2.0 authentication.
•JSON Web Token (JWT). You generate a token using API Manager or API Portal. API consumers use the generated token to invoke the API.
When you create a managed API that invokes a Cloud Application Integration process that uses basic authentication, the authentication method of the managed API is basic. You can then add and remove authentication methods from the managed API. When you change the authentication method, the managed API might become unavailable to users for a very short period of time.
