Systems and methods for generating account permissions for an account on a computing system are provided. In some embodiments, application programming interface (API) interactions involving an external application and the computing system are used to generate a corresponding set of account permissions for the account. API permissions for the external application may also or instead be used to generate the set of account permissions for the account. The set of account permissions may enable the account to access the same resources on the computing system as the external application, which may avoid granting the account overly broad access to the computing system.
