New plugin: Webhook Guard for Stripe webhook verification in Bubble

Plugin builders

Stripe webhook bugs are expensive because they sit right before payment, access, subscription, or fulfilment logic.

Webhook Guard is a server-side Bubble action that verifies and diagnoses Stripe webhook events before the rest of your backend workflow continues.

What it checks:

  • Stripe v1 signature
  • timestamp freshness
  • malformed Stripe-Signature headers
  • invalid JSON
  • unexpected event types
  • test/live mode mismatches
  • common Bubble setup mistakes like using /initialize

What it returns:

  • should_process
  • signature_valid
  • timestamp_fresh
  • event_id
  • event_type
  • error_code
  • error_message
  • warning messages
  • a suggested dedupe key

It does not host the endpoint, call Stripe, retry events, write records, or process payments. The point is narrower: verify first, then let your real workflow decide what to do.
