Which option is used to store authentication details for repeated access to FME Flow?

• A. Custom Transformer
• B. Database Connection
• C. Web Connection
• D. Template

Answer: (C)

Storing authentication details for repeated access to FME Flow is done with a Web Connection. A Web Connection is a reusable resource that holds the web service’s endpoint and the credentials or tokens needed to authenticate. By creating a Web Connection once, you can reference it from multiple workflows in FME Flow, enabling consistent, automated access to the web service without embedding credentials in every workspace. It supports various authentication methods, such as username/password, OAuth, or API keys, and can be secured in the FME Server credential store.

Other options aren’t meant for this purpose: a Database Connection stores database access details, not web service authentication; a Custom Transformer is for data processing logic; and a Template is for parameter values, not secure credential storage.
