Frequently Asked Questions
Does Postmark sign webhooks?
Postmark doesn't use signature verification. Instead, it recommends using a unique, secret webhook URL. ParseBounce generates a unique URL with a secret token for security.
What's the difference between hard and soft bounces in Postmark?
Hard bounces indicate permanent failures (invalid addresses). Soft bounces are temporary issues like full mailboxes. ParseBounce automatically suppresses hard bounces.
Can I track custom data with Postmark events?
Yes! Use Postmark's Metadata feature to include custom key-value pairs like parsebounce_id for campaign tracking.
Do I need separate webhooks for each event type?
Yes, Postmark requires separate webhook configurations for different event types (bounces, complaints, etc.). Point them all to your ParseBounce webhook URL.
