Free, vendor-specific pages that fix Stripe, Shopify, GitHub, Paddle and Twilio webhook signature errors
About Webhook Signature Fix Pages
Developers hit cryptic webhook signature failures (Stripe "No signatures found", Shopify HMAC mismatch, GitHub X-Hub-Signature-256 fails). We publish free, per-error fix pages on a Cloudflare Worker with the exact raw-body + HMAC checklist for each vendor. Owned by Gerald Mitchell / webhookfixes — disclosed as ours. No account required to use the pages.
