SendGrid's Event Webhook provides real-time event data but requires cryptographic verification to ensure authenticity. This Skill standardizes receiving, verifying, and handling SendGrid webhook events across popular web frameworks.
High-intent search queries and answers about installing and using this skill.
Verify SendGrid webhook signatures in FastAPI or Express using ECDSA with SHA-256. This Skill validates signatures against the SENDGRID_WEBHOOK_VERIFICATION_KEY environment variable to prevent replay and tampering, requiring raw request bodies for cryptographic verification.
You can process and parse SendGrid webhook events such as delivered, bounce, open, click, and unsubscribe. The Skill handles payloads containing multiple events simultaneously, allowing your webhook handlers to process batched email event data efficiently.
Yes, raw request bodies are required for SendGrid webhook signature verification. The ECDSA SHA-256 cryptographic validation depends on the unmodified raw payload to accurately verify authenticity and prevent tampering before parsing event data.
Yes, you can test SendGrid webhooks locally with Next.js or Python. The Skill provides practical examples and guidance for integrating webhook handlers in Node.js and Python, including local testing through Hookdeck using test payloads and EC-SHA256 signatures.
SendGrid webhook signature verification fails if the raw request body is modified or parsed before validation. Ensure the SENDGRID_WEBHOOK_VERIFICATION_KEY environment variable matches your SendGrid public key and that your framework delivers the unmodified raw payload to the ECDSA verifier.
Yes, this SendGrid webhook handler supports payloads containing multiple events. It correctly parses batched webhook deliveries containing numerous event types like delivered, bounce, open, and click within a single incoming HTTP request across Express, Next.js, and FastAPI.
