What's API Gateway

webMethods API Gateway enables an organization to securely expose APIs to external developers, partners, and other consumers for use in building their own applications on their desired platforms.

It provides a dedicated, web-based user interface to perform all the administration and API related tasks such as creating APIs, defining and activating policies, creating applications, and consuming APIs. API Gateway gives you rich dashboard capabilities for API Analytics.

APIs created in API Gateway can also be published to API Portal for external facing developers’ consumption. webMethods API Gateway supports REST-based APIs and SOAP-based APIs, provides protection from malicious attacks, provides a complete run-time governance of APIs, and information about gateway-specific events and API-specific events.

API Gateway Features

Configuring the Number of APIs listed on a Page

You can configure the number of APIs that get listed per page in the Manage APIs or the Manage applications page. In each of these pages, you can use the pagination bar at the bottom of the page to navigate from one page to another, the first page, or the last page when there are more than 20 APIs in the list. To change the number of APIs listed in a page, select the required number in the Show # results per page field in the pagination bar at the bottom of the page. The API list now displays only those many APIs in one page as specified. For example, if you select Show 10 results per page, only 10 APIs are listed in one page.

This configuration that you change through the drop down is maintained as long as you are logged in to API Gateway.

The value is set in the drop down is applicable for both APIs and applications listing. For example, if you change the show results to 10 in the Manage APIs drop down, then the number is retained for Manage applications page as well.
