Connectors can be created by using the REST connection. This allows the user to access to a resource. In the following, we will explain the process further. We will create a connector with the REST connection which contains a product list as an example.

...

Creating a new connector without an authentication

In order to create a connector, please open the page Connector under the Design. Created connector than will be available to use in the SmartformForm.

Creating a connector with authentication

If you need an authentication to access a connector URL, you can use either basic authentication or OAuth according to your needs.

Basic Authentication

Basic authentication can be configured via entering the user name and password. In the SAP API, there is an extra configuration feature with the CSRF token. You can configure this feature as well according to your needs.

...

OAuth (Open Authorization)

This authorization method allows you to avoid constant user name and password transfer with a token to secure the access. You can configure this authorization method with user information alongside with the OAuth token information.

form

Custom connectors can be used in the smartformform. In order to show our example, the product list, in the “Select” element of the smartformform, “Connections” section should be opened. The label and the value will be selected from the REST file, which contain information of the products.
