Bubble Zapier Integration Guide
Outbound webhooks, inbound API endpoints, and the webhook settings UI — how to give your Bubble SaaS customers access to 6,000 integrations without building any of them yourself.
Zapier + Bubble Gives Your Customers 6,000 Free Integrations
Your customers are already using dozens of other tools. The moment your Bubble SaaS connects to the tools they use every day — their CRM, their email marketing platform, their project management tool, their Slack workspace — your product becomes embedded in their workflow in a way that is almost impossible to replace. The fastest way to achieve this without building each integration yourself is exposing your Bubble app to Zapier and Make.com.
Bubble as Trigger vs. Bubble as Action
Something happens in your Bubble app → Zapier is notified → Zapier runs an action in another tool.
Example: New contact created in your CRM → add them to your Mailchimp list → send a welcome campaign.
How to build: Store a webhook URL per workspace (customer pastes it from their Zapier account). When the event fires in Bubble, POST to that URL with the event data.
Data model: Add zapier_webhook_url (text) to Workspace. POST to it in the relevant workflow.
Something happens in another tool → Zapier notifies your Bubble app → Bubble runs a workflow.
Example: New customer pays in Shopify → Zapier calls your Bubble API → Bubble creates a support ticket automatically.
How to build: Create a Bubble Backend API Workflow exposed as an endpoint. The customer configures Zapier to POST to that URL when the trigger fires.
Security: Include an API key parameter that validates the calling workspace before processing any data.
Building Outbound Webhooks in Bubble
Workspace:
webhook_url → text (customer pastes Zapier/Make webhook URL)
webhook_events → list of text (which events to send)
webhook_secret → text (for signature validation)
// Send webhook on event workflow (e.g. new contact created)
Only when: Workspace’s webhook_url is not empty
AND Workspace’s webhook_events contains “contact.created”
POST to: Workspace’s webhook_url
Body: {
“event”: “contact.created”,
“workspace_id”: “[Workspace’s Unique ID]”,
“timestamp”: “[Current date/time]”,
“data”: {
“id”: “[Contact’s Unique ID]”,
“name”: “[Contact’s name]”,
“email”: “[Contact’s email]”,
“created_at”: “[Contact’s Created Date]”
}
}
// Inbound: Bubble API endpoint for Zapier to call
Backend API Workflow “zapier_create_contact”:
Parameters: api_key (text), name (text), email (text)
Step 1: Find Workspace by api_key → validate key exists
Step 2: Only when: found Workspace is not empty
Step 3: Create Contact: workspace=found, name=name param, email=email param
The Webhook Settings UI
Every workspace should have a Webhooks settings page where users can: paste their Zapier/Make webhook URL, choose which events to subscribe to (checkboxes per event type), test the webhook with a sample payload, and view a log of recent webhook deliveries with success/failure status. This turns your integration feature into a self-serve product, not a support ticket.
