This is the new documentation of Custom Applications. You can still visit the legacy documentation during the migration from Project-level Custom Applications.


OAuth Scopes and user permissions

OAuth Scopes

Custom Applications can potentially use any of the available commercetools Platform APIs. This is very important and one of the reasons for using Custom Applications in the first place: to be able to extend and improve functionalities of the commercetools Platform and Merchant Center.

Therefore, Custom Applications must specify the list of OAuth Scopes needed by the application.

For example, if you are developing a Custom Application to manage Channels you would probably need the OAuth Scopes view_products and manage_products. On top of that, you might decide to also view Customers information.

To fulfill these requirements, your Custom Application would require the following OAuth Scopes:

  • view_products, view_customers
  • manage_products

These OAuth Scopes must be specified in your Custom Application config, using the oAuthScopes field.

"oAuthScopes": {
"view": ["view_products", "view_customers"],
"manage": ["manage_products"]

Notice here how the OAuth Scopes are grouped by the two fields view and manage.

This grouping determines the mapping and relation between OAuth Scopes and user permissions.

User permissions

In the Merchant Center, you can assign user permissions to Teams to grant or restrict access to certain parts and functionalities of the Merchant Center. See user permissions in Merchant Center for more information.
The same concepts apply for Custom Applications as well. Once your Custom Application has been installed in your Organization, you can assign user permissions for your Custom Application to each specific Team.

Each Custom Application gets a unique pair of user permissions: "view" and "manage."

  • When assigning "view"-only permission to a Team, only the view_ OAuth Scopes are used to authorize API requests.
  • When assigning "manage" permission to a Team, both view_ and manage_ OAuth Scopes are used to authorize API requests.

The permission names are unique to each Custom Application and they derive from the entryPointUriPath, based on the following format: {View,Manage}<EntryPointUriPath>.

Here are some examples:

Ultimately, user permissions should be applied and enforced in the actual Custom Application code. For example to restrict access to certain pages, or to deactivate a button, etc.
