How to Resolve HTTP 503 Stripe Webhook Errors
This error is caused when Stripe cannot make a successful call to the Webhook URL created through the SSA Stripe integration. The URL looks like this:
To fix this, you’ll need to add Stripe’s Webhook IP addresses to Cloudflare’s IP whitelist on your account:
- Obtain all Stripe’s Webhook IP addresses.
- Then add those IP addresses to Cloudflare’s whitelist following their instructions or your hosting providers instructions if they integrate with Cloudflare for you.
After doing so, you can either manually test if the Webhook is successful. Or, you can reach out to the Stripe support team, and they’ll be happy to test it for you.
