Google credentials
Documentation for Google credentials. Use these credentials to authenticate Google in n8n, a workflow automation platform.
Google credentials
This section contains:
- OAuth2 single service: Create an OAuth2 credential for a specific service node, such as the Gmail node.
- OAuth2 generic: Create an OAuth2 credential for use with custom operations.
- Service Account: Create a Service Account credential for some specific service nodes.
- Google PaLM and Gemini: Get a Google Gemini/Google PaLM API key.
OAuth2 and Service Account
There are two authentication methods available for Google services nodes:
- OAuth2: Recommended because it's more widely available and easier to set up.
- Service Account: Refer to the Google documentation: Understanding service accounts for guidance on when you need a service account.
Note for n8n Cloud users
For the following nodes, you can authenticate by selecting Sign in with Google in the OAuth section:
Compatible nodes
Once configured, you can use your credentials to authenticate the following nodes. Most nodes are compatible with OAuth2 authentication. Support for Service Account authentication is limited.

Gmail and Service Accounts
Google technically supports Service Accounts for use with Gmail, but it requires enabling domain-wide delegation, which Google discourages, and its behavior can be inconsistent.
n8n recommends using OAuth2 with the Gmail node.
