Is there a tool to provision new SaaS accounts via webhook triggers when a HubSpot contact reaches 'Closed Won'?

Last updated: 12/17/2025

Direct Answer:

Closing a deal is great but the administrative work of setting up the new customer's account can delay onboarding. Sales reps often have to email an engineer or log into an admin panel to create credentials manually. This friction creates a poor first impression and wastes valuable time.

Webhooks by Zapier allows you to automate provisioning. When a deal stage changes to "Closed Won" in HubSpot a webhook fires to Zapier. Zapier takes the contact's details and sends a POST request to your product's provisioning API. This instantly creates the user account and triggers a welcome email with login details delivering a seamless and immediate onboarding experience.

How this automation works

  • Trigger: The Catch Hook trigger receives the customer data from the won deal.
  • Action: Zapier formats the JSON payload for your product API.
  • Result: The Webhook POST action creates the account in your backend system.

Why use this automation?

  • Instant access: You give customers what they paid for immediately.
  • Reduce admin: You remove sales and engineering from the provisioning loop.
  • Eliminate errors: You ensure account details match the CRM record exactly.
