New collaborator account access security feature
To maintain a safe and secure working relationship between merchants and partners, we've added an additional layer of security when requesting access to a store through a collaborator account. Merchants can choose to set a 4-digit collaborator request code to only receive collaborator requests from those who have the exact code. If this feature is enabled, then you'll need to get the code from merchants to request access to their store.
For more information on the collaborator request code and where to enter the code in your partner dashboard, visit our documentation.
