Create a process

Create a process to define a data model to hold the user details and define activities to manage the user.

Navigate to Workflow > Business processes.
Click New. The process opens in a new browser tab.
Enter User Demo as the Name.

Add a data model

Add a data model to define the structure that will hold the user details.

On the Data models tab, click New.
Change the name of the model to User.
First examine the service you will execute. In a new web browser tab, browse to https://reqres.in/
Scroll down to the methods and click CREATE.

The Request and Response share some common fields (name and job). So rather than creating two models, you can create a single model.

Copy the following JSON:

{
    "name": "morpheus",
    "job": "leader",
    "id": "16",
    "createdAt": "2021-05-05T11:08:27.903Z"
}

In the Add Data model dialog box, select Load from external source, paste the sample JSON into the File content box, and then click Add. The fields are automatically added to the data model structure.

In addition to the fields from the sample JSON, supplement your model with additional information.

Name	Type
Team	Text
updatedAt	Date
