# AWS Transform for mainframe Runtime APIs
<a name="ba-runtime-endpoints"></a>

The AWS Transform for mainframe Runtime uses several web-applications to expose REST endpoints, providing ways to interact with the modernized applications using REST clients (e.g. calling jobs using a scheduler).

The purpose of this document is to list available REST endpoints, giving details about:
+ Their role
+ The way to use them properly 

The endpoints listing is organized into categories, depending on the nature of the provided service and the web-application exposing the endpoints.

We assume that you already have a basic knowledge of using REST endpoints using dedicated tools such as [POSTMAN](https://www.postman.com/), [Thunder Client](https://www.thunderclient.com/), [CURL](https://curl.se/), web browsers, etc ...) or writing your own piece of code to make an API call.
