What you'll need

  • ▸A Stripe account with webhook signing secret
  • ▸A Slack incoming webhook URL (or workspace token)
  • ▸Free Requex.me workspace (no credit card)

Setup

  1. 1

    Generate a Requex webhook URL

    Open Requex.me. A unique URL is created instantly. Copy it.

  2. 2

    Register the URL with Stripe

    In the Stripe Dashboard → Developers → Webhooks, paste your Requex URL. Pick the events you care about (payment_intent.succeeded, charge.refunded, etc.). Stripe returns a signing secret — copy it.

  3. 3

    Open the workflow builder

    Click 'Workflows' in the sidebar. The template loads with five pre-wired nodes: Trigger, Webhook Verify, Filter, Transform, Slack.

  4. 4

    Paste your Stripe signing secret

    Click the Webhook Verify node. Paste the secret. The node uses HMAC-SHA256 against the raw request body with timing-safe comparison — same primitives Stripe documents.

  5. 5

    Add your Slack webhook URL

    Click the Slack node. Paste the incoming webhook URL. The Transform node already formats a clean message with amount, customer email, and a link back to the Stripe dashboard.

  6. 6

    Test it

    Use Stripe CLI: stripe trigger payment_intent.succeeded. Within a second the message lands in Slack. The run trace in Requex shows every node execution with timing.

Why Requex for this

Zapier charges per task and rate-limits aggressively. n8n needs Docker, Postgres, and an upgrade path. Requex runs this for free, has HMAC verification baked in as a node (not a code step), and emits a full execution trace you can inspect when something fails.

Use this template

Open the workflow builder. Drag the nodes shown above. No signup required.
