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

Required:

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

Payload source (choose one):

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

Optional:

• REPLAY_COUNT (default: 2)
• REPLAY_DELAY_SECONDS (default: 0)
• REQUEST_TIMEOUT_SECONDS (default: 15)
• ACCEPT_HTTP_CODES (comma-separated exact HTTP codes accepted as success; default empty = any 2xx)

Run

STRIPE_WEBHOOK_URL=http://localhost:8000/webhooks/stripe \
STRIPE_WEBHOOK_SECRET=whsec_test_123 \
bash scripts/replay-stripe-webhook.sh

Force five duplicate deliveries with a small delay:

STRIPE_WEBHOOK_URL=http://localhost:8000/webhooks/stripe \
STRIPE_WEBHOOK_SECRET=whsec_test_123 \
REPLAY_COUNT=5 \
REPLAY_DELAY_SECONDS=0.2 \
bash scripts/replay-stripe-webhook.sh

Use inline payload JSON:

STRIPE_WEBHOOK_URL=http://localhost:8000/webhooks/stripe \
STRIPE_WEBHOOK_SECRET=whsec_test_123 \
STRIPE_EVENT_JSON='{"id":"evt_test","type":"checkout.session.completed","object":"event","data":{"object":{"id":"cs_test"}}}' \
bash scripts/replay-stripe-webhook.sh

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
