REST Call from JSON Payload — End-to-End Skill

Use this skill to generate the full stack of Mendix integration artifacts from a JSON payload: JSON Structure → Non-persistent entities → Import Mapping → microflow.

Two approaches: This skill uses the inline REST CALL approach (good for one-off calls and quick prototyping). For structured APIs with reusable operations, use the REST Client approach instead — see rest-client for create consumed rest service + send rest request

• optional transform with JSLT data transformers.

Overview — Four Steps

1. CREATE JSON STRUCTURE — store the raw payload and derive the element tree
2. CREATE ENTITY (non-persistent) — one per JSON object type, with attributes per JSON field
3. CREATE IMPORT MAPPING — link JSON structure elements to entities and attributes
4. CREATE MICROFLOW — inline REST CALL that invokes the import mapping (or use REST Client + SEND REST REQUEST)

Step 1 — JSON Structure

mdl 1;
create json structure Module.JSON_MyStructure
  sample '{"key": "value", "count": 1}';

• The executor formats the snippet (pretty-print) then refreshes (derives element tree) automatically.
• The snippet must be valid JSON; use single quotes around it in MDL.
• Escape single quotes inside the snippet by doubling them: ''.
• The derived element tree must stay consistent with the snippet — the executor sorts JSON object keys alphabetically to match json.MarshalIndent output.
