Setting Data Structures
When editing a composite application, you can reference fields from the previous node's payload by selecting variables.
Payload data structures can be configured in two ways.

Payload data structures must match the defined structure exactly; otherwise, fields are not accessible in subsequent nodes.
- Importing JSON Files
Click Import JSON, select the JSON file to be imported, and import it. The payload data structure is displayed in the table.
For example, the content of the imported JSON file is as follows:
{ "id":["123456"], "sort": 1, "attribute":{ "custom_fields":[{ "code":"codeA", "value":"111" }] } }
- Adding a Field
Click Add Root Field, then click the edit icon of the displayed field to modify its name and type. Click Add Root Field to add more fields.
Click the + of an object node to add a subnode or adjacent node.
