Add an Xtension A set of instructions for Nintex Automation Cloud to use third-party API functionality with Nintex workflows. An Xtension may include workflow actions, start events, forms or file control. to connect a new service or data source to your tenancy.


To add a Xtension, you must import a definition for the Xtension into Nintex Automation Cloud. You can either upload the file directly, or import from a publicly available URL that points to an OpenAPI Specification A standard, language-agnostic description of RESTful APIs that can be read by both humans and machines. Formerly known as Swagger..

Looking to upload a product or service's published OpenAPI Specification? See Import a third-party specification.

For this example, we have created a URL for you to import. The Airport-Data API retrieves information about an airport when given the airport's three-letter airport code. You will create the Xtension for the API and then build a basic workflow using the custom action A task that can be performed or triggered within a workflow, such as moving a file, sending an email, or using third-party API functionality. that emails travelers information about the airport they are due to arrive at.
