OAuth 2.0 is an open authorization protocol that enables applications to obtain access to user accounts on an HTTP service. It works by delegating user authentication to the service that hosts the user account and authorizing third-party applications to access the user account. Your application will use OAuth libraries or endpoints to implement the OAuth 2.0 authorization that allows your apps to access Visma APIs. OAuth 2.0 lets applications access specific user data without requiring access to a user's private credentials. It means that an application can use OAuth 2.0 to obtain permission from a Visma company admin to read and write data to their Visma company. This OAuth 2.0 flow is designed to allow your app to access the Visma APIs whether the user is interacting with the application or not. For more information on OAuth, click here.
