Creating a data object using a JSON file

Reduce application development time by using a JSON file to create a data object when a live endpoint is not available.

By using a JSON file, you can create the response schema without connecting to the endpoint. The JSON file is only used by the Data Object wizard to create the schema; it is not saved.
  1. In the navigation pane of App Studio, click Data.
  2. Click Data objects and integrations.
  3. Click New.
  4. In the Data objects name field, enter the name of the data object.
  5. In the Define source data field, click Now.
  6. In the System field, select a system other than Pega to connect to, or click Create new.
  7. In the Method field, select GET or POST.
  8. In the Endpoint URL field, select one of the following options:
    • If you do not know the endpoint URL, enter a sample URL, for example, http://myendpoint.com.
    • Enter the actual URL of your endpoint.
  9. Click Initialize call.
    Result: If you entered a sample URL, an error is displayed. Ignore this error.
  10. Optional: If you are using the GET method, perform the following steps:
    1. Click Sample JSON.
    2. Perform one of the following actions:
      • To upload a JSON file, click Choose File and then follow the prompts to upload the file.
      • In the Response Text field, paste in the response data that you have copied from, for example, a web page or file.
    3. Select the fields that you want to include in the data object and map them to your data view by using the following options:
      • To add the fields to a data object, click Add new. You can change the field name and its type.
      • To add all of the fields from the REST response to the data object using the same field names, click Add all. To change the name and the data object, click the name. To remove a field mapping, click on the name and click the delete icon.
      • To remove all fields from the data object, click Clear all.
