Okta Box Provisioning Error "Could not create new user. 400 - Invalid input parameters in request"
Apr 24, 2026
Okta Integration Network

Overview
When attempting to provision a new user to the Box application in Okta, with the "Admin" role assigned, the Box API returns an error:
Could not create new user. 400 - Invalid input parameters in request
Applies To
- Box
- Provisioning
- 400 Error
- Okta Classic Engine
Cause
The Box application only allows for one primary "Admin" account. When trying to provision a new user from Okta and assign them the "Admin" role, the Box API rejects the request because a primary admin already exists, resulting in the error.
Solution
To resolve this issue, assign the user a different role in the Box application settings in Okta.
- Instead of "Admin," assign the user the "Co-Admin" role.
- Retry the provisioning task. The user will now be created successfully with the appropriate co-administrator permissions.
This adjustment aligns with Box's administrative model and will ensure the user is provisioned correctly.
