Do I need more than one access token if I am working with multiple NPIs or trading partners?

Access tokens are for the application and you do not need different ones for each NPI or trading partner. For security purposes, the tokens expire one hour after being acquired. Note that if you use one of our client libraries, you don’t have to handle authentication yourself; simply put in your Client ID and Client Secret and the library does the rest!
