This article shares some typical use cases you can support, as well as an example flow that supports each use case. You're certainly not limited to these use cases, but they can be a helpful jumping off point as you plan your implementation.
If your company has multiple employees, you can invite them to join your Wix account, whether or not they already have a Wix account.
Call Create Invite with the employees email addresses, the roles to assign (referred to here as policies), and any specific assets they should not have access to (referred to here as resources). If no assets are specified, the employee will be given access to all assets in the account.
When the employee accepts the invitation, their user ID is created (if relevant) and assigned as a team member of your account.
