postmark-webhooks

What problem does it solve?

This skill provides a ready-to-use blueprint for receiving and processing Postmark webhook events across major runtimes, enabling real-time handling of email events such as Bounce, Delivery, Open, Click, SpamComplaint, and SubscriptionChange.

Core Features & Use Cases

• Cross-runtime webhook handling: Templates and examples for Express, Next.js, and FastAPI to cover common backend stacks.
• Payload validation: Ensures essential fields like RecordType and MessageID are present before processing.
• Secure authentication guidance: Clear guidance for token-based or basic authentication to protect webhook endpoints.
• On-demand event routing: Routes events to framework-specific handlers with structured logging and error handling.
• Local development & testing: Includes guidance and patterns to test webhooks locally using tooling like Hookdeck.

Quick Start

Start by configuring your webhook in Postmark to point to your endpoint (using token or basic auth), then choose an example framework (Express, Next.js, or FastAPI), set up the environment, and run the server to begin processing incoming webhooks.
