Call REST Endpoint task

The Call REST Endpoint task lets you call any third-party REST API from your integration. The response from the REST API call will be available to you in an integration variable and can be used in other down-stream tasks.

Authentication

To use this task, you might need to create an authentication profile. Application Integration uses an authentication profile to connect to an authentication endpoint for the REST API call. If your API does not require authentication, then the Authentication profile field in the task configuration pane can be left empty.

If you have not created an authentication profile before configuring an integration task, you can access the profile creation dialog by clicking + New authentication profile in the task configuration pane. For more information about creating authentication profiles, see Create a new authentication profile.

The Call REST Endpoint supports the following authentication types:

Configuration properties

The following table describes the configuration properties of the Call REST Endpoint task.

HTTP headers HTTP header key: String

Value: String

HTTP headers required for the REST API call.

The HTTP headers are in the form of key-value pairs where key is the key name and the value is the corresponding key value. You can enter more than one key-value pair by clicking on the plus icon.

Follow redirects Boolean Follow URL redirects.

You can select any one of the values:
