+   If you don't have a schema, but you have a sample payload in JSON format, 
+   you can generate a schema from that payload.
+
+   1. In the Request trigger, choose

+
+   1. Under **Enter or paste a sample JSON payload**, 
+   enter your sample payload, and then choose **Done**.

+   This sample payload generates this schema that appears in the trigger:
+
+   ```json
+   {
+      "type": "object",
+      "properties": {
+         "address": {
