How do I generate a signed Stripe rest webhook request locally?
I think the issue has to do with the curl call. The -d/--data argument is stripping any line breaks from your json and the resulting digest computed by Stripe::Webhook.construct_event is different than what you've computed in the terminal.
After generating a digest I curled at my webhook endpoint:
Using the standard -d, threw an error saying the signature was invalid
curl -s -X POST http://localhost:3000/webhook -H "Stripe-Signature: t=1509309309,v1=a2e2776cd5a57ba60355f7cfa3bcdd1d69e773373a0da" -d @./webhook.json.tmpWhereas, specifying the --data-binary returned a valid signature
curl -s -X POST http://localhost:3000/webhook -H "Stripe-Signature: t=1509309309,v1=a2e2776cd5a57ba60355f7cfa3bcdd1d69e773373a0da" --data-binary @./webhook.json.tmp
The best is to use Stripe CLI :https://github.com/stripe/stripe-cli
You can forward the request to localhost address.
