For example, the Foreign Exchange Rates API I use in this project is free and can be accessed as many times as needed without a password. When we work with APIs, we start by looking at its documentation to understand what data is available to us, if there is a maximum number of requests we can send, whether this API requires authentication or payment, etc.If you know about APIs, then feel free to scroll further to the first step.

This means that users will need to manually refresh their workflows in Tableau Prep.įee: No charge included in OCTO’s BI program.Īlso check out other Workshops in Online.Usually, to work with data in Tableau Prep Builder, we directly connect to a file or a database.
