Using the Data Mapping task, resolve a JSON reference in a template JSON that contains a $variable$ reference. Store the output in a new JSON variable.
Click Integrations from the left navigation menu to open the Integrations page.
Select an existing integration or create a new integration by clicking Create integration.
If you are creating a new integration:
Enter a name and description in the Create Integration dialog.
Select a region for the integration.
Select a service account for the integration. You can change or update the service account details of an integration any time from the infoIntegration summary pane in the integration toolbar.
Click Create.
This opens the integration in the integration editor.
In the integration editor, click publishUpload/download menu and then select Upload integration.
In the file browser dialog, select the file that you saved in step 1, and then click Open.
A new version of the integration is created using the uploaded file.
In the integration editor, click Test.
Click Test integration. This runs the integration and displays the execution result in the Test Integration pane.

Enter a name and description in the **Create Integration** dialog.\n 2. Select a region for the integration. **Note:** The **Regions** dropdown only lists the regions provisioned in your Google Cloud project. To provision a new region, Click **Enable Region** . See [Enable new region](/application-integration/docs/enable-new-region) for more information.\n 3. Select a service account for the integration. You can change or update the service account details of an integration any time from the info **Integration summary** pane in the integration toolbar. **Note:** The option to select a service account is displayed only if you have enabled integration governance for the selected region.\n 4.
