You must have Admin permissions to allocate credits (contacts) to other users in your Datanyze account.
Note: In this article, the terms Credits and Contacts are synonymous.
Account administrators allocate credits when they want each user to have a set amount of credits. Without allocating credits, users have access to the full pool of credits purchased.
Go to your Account Settings and select Users.
Find the user you’d like to manage credits for and select Actions > Manage > Allocate Credits > Change or update the amount of credits the user has access to > Save.
