Webhooks Not Receiving or Processing Data in Base44
You've set up a webhook endpoint in your Base44 app to receive data from an external service (such as payment notifications from Stripe, form submissions from another platform, or updates from a CRM), but the webhook data never arrives or is not processed correctly.
Webhooks are crucial for real-time integrations. When they fail, your app misses important events like payment confirmations, status updates, or new lead notifications, potentially causing business-critical failures.
The failure may be silent: the external service reports successful delivery but your Base44 app shows no record of receiving the data.
Error Messages You Might See
Common Causes
- The webhook URL configured in the external service doesn't match the actual endpoint in your Base44 app
- The webhook endpoint requires authentication that the external service isn't providing
- The incoming payload format (JSON structure) doesn't match what the Base44 handler expects
- The webhook handler takes too long to process and the external service times out before receiving a response
- The webhook endpoint only exists in the editor environment and wasn't deployed to production
How to Fix It
Verify the webhook URL by sending a test request using a tool like webhook.site or Postman. Confirm the endpoint is accessible and returns a 200 response.
Check the external service's webhook delivery logs (most services like Stripe provide these) to see if the delivery attempt failed and what error was returned.
Ensure the webhook endpoint is deployed and accessible in your production environment. For webhooks that handle critical business events, a developer can implement proper error handling, retry logic, and payload validation.

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Get HelpFrequently Asked Questions
Why isn't my Base44 webhook receiving data?
Check the webhook URL is correct and accessible in production (not just the editor). Review the sending service's delivery logs for error codes or timeout messages.
How do I test webhooks in Base44?
Use a tool like Postman to send a test POST request to your webhook URL with a sample payload. Check if the endpoint responds with 200 and processes the data correctly.
