Webhook for Forms

Hallo guys,
I am busy developing a website of a client of ours.
They are creating a subdomain for a user portal that a developer is creating for them. They want to use their main domain for users to register and pay for questions via forms. They want to use Webhooks to get the data that the users that register and ask questions to be captured into their subdomain database.
Can this be done with forms?
Kind Regards
Stephan
