Alchemy uses the x-alchemy-signature as an authentication token to verify the source of your webhook requests and responses. This ensures that the data you receive is coming directly from Alchemy and not from a malicious source. Here’s a quick guide on what the x-alchemy-signature is and how to find your Alchemy auth token.

What Is the x-alchemy-signature?

The x-alchemy-signature is a security feature provided by Alchemy to authenticate the origin of your webhook responses. It verifies that the response you receive is from Alchemy and not an unauthorized or malicious source. This signature is sent along with every webhook request, ensuring the integrity of your data.

Where Do I Find My Alchemy Auth Token?

To find your Alchemy authentication token:

1. Log in to your Alchemy Dashboard.

2. On the left-hand panel, navigate to the Webhooks section.

3. In the upper-right corner of your Notify Dashboard, click the AUTH TOKEN button.

4. Copy your x-alchemy-signature (auth token) from here.

This token will be used to verify the source of your webhook events and can be used in webhook integrations.

By following these steps, you can easily locate your x-alchemy-signature and ensure that your webhook requests are secure and authenticated by Alchemy!
