Mollie Webhooks

When to Use This Skill

• Setting up a Mollie webhook handler (classic webhookUrl or next-gen subscription)
• Verifying the X-Mollie-Signature header on next-gen webhooks
• Understanding why classic Mollie webhooks have no signature to verify
• How do I confirm a Mollie payment status from a classic webhook?
• Handling payment status changes: paid, authorized, canceled, expired, failed
• Why does my Mollie webhook only contain an id?

Two Webhook Systems (Read This First)

Mollie runs two webhook systems side by side. They are secured differently, so work out which one you are receiving before writing a handler.
