## Supported authentication methods

View n8n's [Advanced AI](../../../../advanced-ai/) documentation.

## Using API key

To configure this credential, you'll need a [Zep server](https://www.getzep.com/) with at least one project and:

- An **API URL**
- An **API Key**

Setup depends on whether you're using Zep Cloud or self-hosted Zep Open Source.

### Zep Cloud setup

Follow these instructions if you're using [Zep Cloud](https://app.getzep.com):

1. In Zep, open the **Project Settings**.
1. In the **Project Keys** section, select **Add Key**.
1. Enter a **Key Name**, like `n8n integration`.
1. Select **Create**.
1. Copy the key and enter it in your n8n integration as the **API Key**.
1. Turn on the **Cloud** toggle.

### Self-hosted Zep Open Source setup

Deprecated

The Zep team [deprecated the open source Zep Community Edition](https://blog.getzep.com/announcing-a-new-direction-for-zeps-open-source-strategy/) in April, 2025. These instructions may not work in the future.

Follow these instructions if you're self-hosting Zep Open Source:

1. Enter the JWT token for your Zep server as the **API Key** in n8n.
1. Make sure the **Cloud** toggle is off.
1. Enter the URL for your Zep server as the **API URL**.
