Use authentication methods in workflows

Authentication methods are reused in workflows through node configuration: the node applies the access at execution time, without the secret ever appearing in the workflow.

Before you start

• Have created an authentication method.
• For the general variable mechanism (environment-based resolution), see Variable management.

Select a method in a node

1. Open the node configuration.
2. Fill in the Auth or Authentication methods section.
3. Select the method in the dropdown list.

The field can also directly contain an authentication method or a dictionary variable.

Nodes that support authentication

Node	Supported methods
HTTP(S) Request	Basic Auth, Bearer, API Key
FTP nodes	FTP/SFTP (credentials or private key)
Google Pub/Sub Send	GCP authentication method
AWS SQS Send	AWS access key and secret access key
AI Agent	Provides the model token via an authentication method
Code	All — methods declared in the Auth tab, used in the script via libs.ecosystemCredentials

Simple API key

For a simple key to send in a header or query parameter, a dictionary variable is enough — see Dictionaries.
