You are able to access your form submission schema from the forms menu of the console.
This is commonly used when creating integrations through Power Automate (Microsoft Flow) and when using the Parse JSON Connector to pull specific information out of the form submission.
As a developer, you may also wish to use this to validate submissions in your integration code.
Getting the Form Schema
In the console, on your Forms List page, you are able to access the schema by clicking on the three-dot quick menu on the right-hand side of each form item.
You will then see an option for View Schema
This will open up the forms JSON Schema, giving you the ability to view and copy the schema.
Using the Schema with Power Automate
If you are accessing the schema for the purpose of a Power Automate integration, then the schema here can be copied and pasted directly into the Parse JSON Connector in Power Automate.
