## What it is
Standard Webhooks is an open specification plus reference libraries and tools for sending and verifying webhooks securely and consistently. It defines common HTTP headers, payload conventions, and HMAC signature verification so webhook providers and consumers can interoperate.

## Use cases
- send webhooks securely from my api
- verify webhook signatures in python
- standardize webhook payloads across providers
- implement webhook signing with hmac
- consume webhooks from multiple providers with one library
- avoid replay attacks on webhook endpoints

## When to choose
- you are building an API that sends webhooks and want industry best practices
- you need to verify incoming webhooks signed per the Standard Webhooks spec
- you want interoperability with providers like Svix, Twilio, or Zapier that follow the standard

## When to avoid
- you must integrate with a provider that uses its own proprietary webhook format
- you need a full webhook sending service rather than a spec and client libraries

## Facets
- artifact type: library
- maturity: active
- function: webhook, security, sdk, api-framework
- domain: apis, web-development, developer-tools, security
- platform: cross-platform, python, jvm, go, rust
- tags: webhooks, specification, http-callbacks, signature-verification, interoperability, nodejs
