Automatically Batch Create Hubspot Contacts from External Webhooks
Webinar registrations, event signups, and form submissions trigger automatic contact creation in Hubspot—no manual import or data entry needed.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create batch of contacts
Creates up to 100 new contact records in hubspot crm, optionally associating them with existing crm objects; ensure associated object ids are valid.
Why this helps
People register for your events or fill out forms externally but you manually import them into Hubspot, creating delays and data entry errors.
- Contacts are created in Hubspot within seconds of signup
- No manual import or data entry errors
- Leads enter your nurture flows immediately
- Complete registration trail in your CRM
Setup
Build it in a few focused steps.
- 1Connect Hubspot to Notis and get your webhook URL
- 2Configure your event platform (Eventbrite, webinar tool, form builder, etc.) to POST registration data to the Notis webhook
- 3Tell Notis: 'Create a batch of Hubspot contacts when you receive a webhook from [event platform]' or set up in Automations
- 4Map the registration fields to Hubspot contact properties (Notis does this automatically for email, name, etc.)
- 5Choose your notification channel
- 6Test by registering for your event and verifying the contact appears in Hubspot
Questions about this workflow
What if a registrant already exists in Hubspot?
Notis checks for duplicates and updates existing contacts instead of creating new ones.
Can I add registrants to specific Hubspot lists or workflows?
Yes, ask Notis to automatically add imported contacts to a nurture list or workflow.
How long does it take for contacts to appear after registration?
Typically within seconds. If your webhook tool buffers data, there may be a slight delay.
