Get the generate code from the Airtable iframe

I have called the iframe in my shopify. Iframe is showing a form and when form will submit it will generate a code. How can I get this code from the iframe? I have tried so many things but I have not got any success.
Please help me. If you can help me

I don’t think you can get the code from the iframe.

If it’s a code you are generating in your Airtable database, then you’d need to get it from your database directly (via API, presumably).

If you are talking about a code that Airtable generates, then presumably you’d have to grab it from the response hash (the json returned by the server when a user submits the form).
