This connector uses Basic Auth, which means that you do not need to set up a Provider App before getting started. (Provider apps are only required for providers that use OAuth2 Authorization Code grant type.)To start integrating with Nutshell:
Embed the InstallIntegration UI component. The UI component will prompt the customer for their username and password.
Start making Proxy Calls, and Ampersand will automatically attach the correct header required by Basic Auth. Please note that this connector’s base URL is https://app.nutshell.com/api/v1.
