A comprehensive collection of guides covering everything you need to know about webhooks. From basic concepts to advanced implementation strategies, these guides will help you master webhook development and management.
Webhook Glossary
Webhook and event terms often overlap (e.g., provider / source / publisher / sender). We’ve categorized these synonyms so no matter what terminology you’re used to, you can follow along easily. This glossary helps you map your mental model to Hookdeck and see exactly where it fits in your architecture.

Webhook Providers
Webhook providers are platforms that publish webhooks. Since there’s no standard for formats, security, or best practices, it is important to always review the provider’s documentation to avoid broken integrations or security vulnerabilities.

Webhook FAQs
| Question | Answer |
|---|---|
| How do I verify that a webhook is legitimate and not from a malicious source? | Because security is not enforced consistently across providers, it's on you implemnet the required verification. If you skip this, you're exposed to spoofed or malicious traffic. |
| Can I receive duplicate webhook events? | Yes. Duplicates are expected because providers retry aggressively using a at-least-once delivery guarantee, so it's your responsibility to make processing idempotent and protect downstream systems. |
| What happens if my webhook endpoint is down? | Providers retry, but only for a limited time and with varying strategies. You shouldn't rely on retries but rather implement your own queuing, dead-letter handling, and replay strategy. |
| How can I handle high-volume webhook traffic? | Most providers will push as fast as events occur. It's your job to buffer, queue, and scale workers so your system doesn't crash under bursts. |
| Can I replay or redeliver webhooks? | Providers often offer limited replays, but they're not reliable for end-to-end recovery. To guarantee resilience, you must keep your own event store and implement your own replay capability. |
