How to integrate
Follow these Bubble-specific instructions
Get your Waitlister API endpoint
Login to Waitlister → Overview → copy your waitlist key. Your API endpoint is:https://waitlister.me/s/YOUR_WAITLIST_KEY
Create a Bubble form with inputs
In Bubble editor, add form elements:
• Add an Input element (set Content format: Email)
• Add another Input for name (optional)
• Add a Button element
Create workflow for button click
Click on the button → Start/Edit workflow. This opens the workflow editor.
Add API Connector plugin
If not already installed: Go to Plugins tab → Add plugins → search "API Connector" → Install.
This free Bubble plugin lets you call external APIs like Waitlister.
Set up API call in API Connector
Go to Plugins → API Connector → Add another API:
• Name: "Waitlister"
• Add a new API Call: "Submit to Waitlist"
• Method: POST
• URL: https://waitlister.me/s/YOUR_WAITLIST_KEY
• Body type: Form-data
• Add parameters: email (text), name (text)
URL: https://waitlister.me/s/YOUR_WAITLIST_KEY
Method: POST
Body Type: Form-data
Parameters:
- email (text)
- name (text)Initialize the API call
In API Connector, enter test values for email/name, then click Initialize call. This tells Bubble the expected response structure.
Add API call to workflow
Back in the workflow editor, add action:
• Plugins → Waitlister - Submit to Waitlist
• email: Input Email's value
• name: Input Name's value
Add success feedback
After the API call action, add:
• Show message: "You're on the list!"
• Reset inputs: Clear both input fields
• Optional: Navigate to thank you page
Add error handling (optional)
In workflow, add condition to check if API call was successful. If failed, show error message. Bubble makes this easy with "Result of step X is empty" conditions.
Whitelist your Bubble domain
In Waitlister → Settings → Configure → Whitelisted domains, add:
• Development: yourapp.bubbleapps.io
• Production: yourdomain.com
Development: yourapp.bubbleapps.io
Production: yourdomain.comTest the complete flow
Click Preview, submit the form with test data, check Bubble debugger for API response, and verify signup in Waitlister dashboard.
Add custom logic (optional)
Before API call, add conditions to:
• Check if user already exists in your database
• Send to different waitlists based on user type
• Trigger additional Bubble workflows
• Store in Bubble database too (for your records)

Quick fixes for Bubble-specific problems
Check "Render HTML" is enabled in element properties. HTML elements only show in preview mode, not in the editor. Click Preview to see the actual form. Verify the script tag is included.
Check API Connector settings - ensure Body type is "Form-data" not "JSON". Verify URL has your correct waitlist key. Check that parameters match your form inputs. Use Bubble's debugger to see exact error.
Increase the HTML element height in properties (try 500-600px). Or adjust data-height in the embed code. Set HTML element to "fit height to content" if available.
Click the button → verify "Start/Edit workflow" shows your workflow. Check button isn't disabled by conditions. Use Bubble's inspector to check element properties and states.
Add your Bubble domain to Waitlister whitelisted domains. Include both .bubbleapps.io and your custom domain. CORS errors mean the domain isn't whitelisted.
Make sure you're using POST method, not GET. Check that test values are provided for all parameters. Try with simple test data first ([email protected]). Ensure URL is correct.
Wrap HTML element in a responsive Column (uncheck "Fixed width"). Set max-width in the inline style. Test in Bubble's responsive preview across all breakpoints.
The embed method uses zero WU. For API method, each submission is 1 API call = minimal WU. If seeing high WU, check for workflow loops or unnecessary database operations.
For embed method: customize in Waitlister dashboard. For custom forms: use Bubble's native styling - apply your app's color palette, fonts, and button styles.
Go to Plugins tab (left sidebar) → Add plugins → Search "API Connector" → should be first result. It's a free core Bubble plugin developed by Bubble.
Common questions
About Bubble integration
The embed method works on Bubble's free plan. For the API workflow method, you need at least a Personal plan ($29/month) to use the API Connector and remove Bubble branding. Custom domains require paid plans.
The embed method uses ZERO WU. For the API method, each submission = 1 API call = minimal WU impact. Much more efficient than building waitlist management in Bubble which would use WU for database operations.
Yes! Use the form action method with API Connector. Trigger any Bubble workflow on waitlist signup - send welcome emails, create database entries, add to user table, or run custom logic.
Yes! For embed method, wrap the HTML element in a responsive Column. The Waitlister form is mobile-responsive automatically. For custom forms, use Bubble's native responsive features.
Yes! In your workflow after the Waitlister API call, add "Create a new thing" action to store the same data in your Bubble database. This gives you local backup and lets you use Bubble's search/filter.
In your Bubble workflow, before calling Waitlister API, add a condition: "Do a search for Users:count = 0" to check if email exists. Only proceed with API call if user is new. Show different message for existing users.
Absolutely! Collect waitlist signups, then manually approve users. Export waitlist from Waitlister, import to Bubble database with "Beta User" status. Use Bubble privacy rules to control access based on this field.
Yes! Works with both old and new responsive engines. For new engine, use flexible layouts and the form adapts automatically. Test in preview mode across all breakpoints.
Yes! Create multiple Bubble pages with different designs, each with a waitlist form. Use Bubble's built-in A/B testing or send traffic to different pages. Track which converts better in Waitlister analytics.
Export waitlist from Waitlister to CSV. Import to Bubble database or your email tool (SendGrid, Mailchimp). Send launch notifications with signup links to convert waitlist to active users.
Yes! Connect your custom domain in Bubble (requires paid plan), then add that domain to Waitlister whitelisted domains. Everything works seamlessly with custom domains.
Much faster! Building waitlist management in Bubble would take days of work - database setup, workflows, email verification, spam protection, analytics, exports. Waitlister gives you all of this in 10 minutes.
