The first thing you'll need to do to get started with hooking up OneDrive with Zapier and hundreds of other services is to add your OneDrive Account to Zapier. Click to add a OneDrive account in your Zap.
Next you will give your new Account a name or label, which is just a handy name for you to recognize within Zapier. It doesn't matter what you name it.
You should then get a pop-up window from OneDrive asking you to log-in to authorize the connection between that OneDrive account and Zapier. If you are already logged in the pop up will show right away.
You will then click "Yes" to let OneDrive connect to Zapier.
Logging into and authorizing OneDrive finishes the process! Your OneDrive account is now connected to Zapier.
