webhook trigger inside the form, before submission

[deepak9780097800]

When a user enters their mobile number in the Pabbly form, a webhook should trigger immediately. Using that number, Pabbly Connect should fetch data from my database and then dynamically use those values in the same form before final submission.

Required Flow:

1. User enters their mobile number in the form.
2. A webhook is triggered instantly.
3. Pabbly Connect uses the number to retrieve data from my database (e.g., pending invoice amount).
4. The fetched value (e.g., Pending Amount = ₹4,500) is auto-filled or used inside the form.
5. On final form submission, the fetched value is also submitted and stored along with user details.

Example Use Case:

• User enters: 98XXXXXX00
• Webhook triggers
• System fetches: Pending Invoice = ₹4,500
• This amount is automatically added to the form
• User submits the form
• Final submission includes the pending amount

I need an automation where the process works like:

On number input → Webhook → Fetch DB values → Populate form → Final submit

Hello @deepak9780097800,

Thank you for reaching out to us.

At the moment, the use case you described would not be possible. A webhook cannot be triggered before the form is submitted, and no response can be sent to the webhook until the form is actually submitted.
