## Using Gemini(PaLM) API key <a href="#using-geminipalm-api-key" id="using-geminipalm-api-key"></a>

To configure this credential, you'll need:

* The API **Host** URL: Both PaLM and Gemini use the default `https://generativelanguage.googleapis.com`.
* An **API Key**: Create a key in [Google AI Studio](https://aistudio.google.com/apikey).

{% hint style="warning" %}
**Custom hosts not supported**

The related nodes don't yet support custom hosts or proxies for the API host and must use `https://generativelanguage.googleapis.com`.
{% endhint %}

To create an API key:

1. Go to the API Key page in Google AI Studio: <https://aistudio.google.com/apikey>.
2. Select **Create API Key**.
3. You can choose whether to **Create API key in new project** or search for an existing Google Cloud project to **Create API key in existing project**.
4. Copy the generated API key and add it to your n8n credential.
