You can enable business-to-business communication between trading partners using Application Programming Interfaces (APIs). In addition to exchanging XML, EDI, flat files documents and so on, partners can invoke the exposed APIs to exchange information. These APIs are available by associating Trading Networks with a webMethods API Gateway instance. A partner can access the APIs that appear in the Partner Profiles and the associated Partner Groups pages. The API access key and the authentication mechanism to access the APIs also appear on the APIs tab of the Partner Profiles page. An Administrator can provide a user to view and edit permissions to add or delete the appearance of an API in the Partner Profiles page. If you are unable to view an API despite having appropriate permissions, contact the Administrator to configure a valid API Gateway instance. You must also have a basic understanding of APIs and must know how to access them.

For information on how to invoke an API, see the webMethods API Portal Consumer's Guide.
