Balbooa Form Payment Tweak

My Joomla site runs Balbooa Forms tied to the Mollie payment gateway. Right now the form submits immediately; I need the submission to be processed only after Mollie confirms a successful payment and, instead of any redirect, a success message must appear on the same page.

You will have FTP and Joomla-admin credentials, plus remote AnyDesk access to the Mollie dashboard. Database access is off-limits, so the solution must live entirely in the plugin/extension layer or via a safe override.

Deliverables
• Hold form submission until Mollie returns a paid status, then save the record and fire Balbooa’s normal actions.
• Display a customizable success message inline; no page change.
• Gracefully handle failed or cancelled payments without storing the submission.

Please send a brief, concrete proposal outlining how you will hook into Balbooa’s events or Mollie webhooks, the estimated turnaround (I need this ASAP), and any similar tweaks you’ve delivered.
