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.

Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.

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.
