Unique submission IDs, API endpoint for PDF, bugfixes

Two small, but useful (at least to those who requested these) improvements were added today.

Unique submission IDs

Each submission now has a public (to admins), unique ID. These IDs start at 1 for each form. Within the form settings, you can optionally set a prefix and/or a suffix. So you could create something like Student-NUMBER-2025, or whatever you need. The IDs is auto-incrementing.

For customers using webhooks, the updated response looks like this, including a number (integer) and number_formatted (string, with prefix or suffix) key:

{
  "id": "e5b579ae-daf8-4b36-b300-d622df17a0de",
  "number": 123,
  "number_formatted": "Prefix-123-Suffix",
  "form_id": "cc141639-0ff1-4a92-b35d-6b0373db4521",
  "form_name": "Webhook Test",
  "referrer": null,
  "data": [
    [
      {
        "label": "Full name",
        "response": "John Doe",
        "uuid": "fb39181c-b13f-4e54-8283-0b0eed7f6cca",
        "custom_key": "full_name"
      },
      {
        "label": "Email address",
        "response": "john@example.com",
        "uuid": "a95f6f9e-da14-4049-86b1-78eb9a558dbc",
        "custom_key": "email_address"
      },
      {
        "label": "CV",
        "response": [
          "https://userdata.deftform.com/full-path-to-file/filename-abc.pdf"
        ],
        "uuid": "f3c94dde-85e2-4a56-b814-266988de0000",
        "custom_key": null
      }
    ]
  ]
}

Create PDF endpoint for API

We have added a new API GET endpoint: /response/{UUID}/pdf

This endpoint allows you to generate a PDF of a submission on the fly. The API response looks like this:

{
    "success": true,
    "data": {
        "pdf_url": "ABSOLUTE-URL-TO-PDF-FILE"
    }
}

The UUID can be obtained via the /responses/{formId} endpoint. You can read more about our API here: https://help.deftform.com/api/endpoints
