Stripe Webhook Replay Lab

Use this skill to replay the same signed Stripe webhook event multiple times against your endpoint and validate idempotency behavior.

What this skill does

• - Loads a Stripe event payload from a JSON file or inline env var
• Generates valid Stripe Stripe-Signature headers using your webhook secret (whsec_...)
• Replays the exact same payload N times to simulate duplicate deliveries/retries
• Prints per-attempt HTTP status and latency with a pass/fail summary

Inputs

• - STRIPE_WEBHOOK_URL (target endpoint)
• INLINECODE3 (Stripe endpoint secret used to verify signatures)

Payload source (choose one):

• - STRIPE_EVENT_PATH (default: fixtures/sample-checkout-session-completed.json)
• INLINECODE6 (inline JSON payload; overrides STRIPE_EVENT_PATH)

Optional:

• - REPLAY_COUNT (default: 2)
• INLINECODE10 (default: 0)
• INLINECODE12 (default: 15)
• INLINECODE14 (comma-separated exact HTTP codes accepted as success; default empty = any 2xx)

Run

CODEBLOCK0

Force five duplicate deliveries with a small delay:

CODEBLOCK1

Use inline payload JSON:

CODEBLOCK2

Output contract

• - Prints payload event id/type when available
• Logs each replay attempt: status code + elapsed milliseconds
• Exit 0 if all attempts pass success criteria
• Exit 1 if any attempt fails or inputs are invalid
