Payment Webhook Handler

Payment Webhook Handler

A complete inbound payment event pipeline: parse the webhook JSON, branch on success vs failure, email the customer a receipt, and ping your team on Slack when a charge fails — all without writing a line of server code.

What this workflow does

1. Input receives the raw Stripe webhook JSON body
2. Set extracts event type, amount, currency, and customer email from the payload
3. Condition checks whether event_type equals payment_intent.succeeded
4. Send Email (success path) sends a payment receipt to the customer
5. Slack (failure path) alerts your ops channel with the failure reason
6. Output returns the parsed event for downstream logging

Use cases

• Stripe, Paddle, or LemonSqueezy webhook processing
• SaaS subscription lifecycle events (payment succeeded, failed, refunded)
• E-commerce order confirmation and failed-payment recovery

Setup

Point your payment provider's webhook endpoint at a Heym webhook trigger URL (replace the textInput node with a Webhook trigger node for production). Add an SMTP credential to Send Email and a Slack credential to the alert node.
