About Accessing Design Center
You need to meet the following requirements for accessing Design Center, using its features, deploying apps to the design environment, and publishing designs to Exchange:
Be assigned to the Design Center Developer role or be the Organization Owner
The user who first signs up for the Anypoint Platform organization is the Organization Owner.
Be assigned to the CloudHub Admin role for the Design environment
Be assigned to the Exchange Contributor role
Belong to an Anypoint organization that has at least one CloudHub Design Environment with 0.2 VCores of available capacity
To deploy to the production environment from Design Center, your user account also needs to be assigned to a CloudHub Developer role specifically for the production environment.
You need to be assigned multiple roles to have the same permissions in separate environments. To assign a set of roles to multiple users, you can create a custom role. Roles are assigned per environment.
