Webhook Signature Validation Behind Reverse Proxy

Questions
1

If TLS termination happens upstream (e.g., Cloudflare or Traefik), can modified headers affect webhook signature validation for providers like Stripe?

Describe the problem/error/question

What is the error message (if any)?

Hi @Ogunmokun_Adeyemi , welcome to the n8n community :tada: !

I’d also check forwarded headers like content-encoding and transfer-encoding. If the proxy alters these without matching the body, it can cause subtle signature mismatches. Keeping headers and payload consistent is just as important as raw body integrity.
