Hey @kyaw, Before sending your webhook data, Coinbase Commerce validates that the connection to your service is secure. For this to work, your server must be correctly configured to support https . Please have a look here Using Webhooks | Coinbase Cloud and try establishing a Webhook connection again.

We hope this helps. We’d be happy to answer any more questions.

Thank you and have a nice day!
