# Webhook security

> To ensure the integrity of the webhooks you receive, we recommend verifying the signatures of the webhooks you receive. The webhook platform we use, Svix, provides packages for multiple languages that make verifying signatures easy.

  npm install svix
  // Or
  yarn add svix

  ```Python Python theme={null}

First, obtain your webhook secret on the configuration page for your webhook under the **Signing Secret**:

<img src="https://mintcdn.com/goody/UtvUnxw3LhFrdzGW/images/signing-secret.png?fit=max&auto=format&n=UtvUnxw3LhFrdzGW&q=85&s=63eae4c413f0f92078e70447d0bf9c96" alt="" width="2360" height="552" data-path="images/signing-secret.png" />

Then, to verify the webhook, pass your signing secret with the headers and raw payload body to the verify method.

<Warning>
  **Make sure to use the raw request body for the payload**

  If your framework
  parses JSON, you'll want to use the raw request body instead of the parsed
  JSON.
</Warning>
