Creating Custom Users to Perform API Controller Operations¶

To perform tasks using the API Controller, a particular user must have required permissions and scopes. By default, a user with admin role is allowed perform all the tasks.

Steps to Create a Custom User who can Perform API Controller Operations¶

Create a role named custom_role with API Create, API Publish and API Subscribe permissions (along with Login permission) and assign it to a user.

Tip

Refer Managing Users and Roles to learn how to create a user role with permissions and assign it to a user.
Assigning the required scopes for the custom_role can be done using 2 methods.
1. Using API-M management console.
  1. Sign in to the API-M management console (https://<APIM_Host>:<APIM_Port>/carbon) as a tenant admin user.
  2. Navigate to Main > Resources > Browse
  3. Enter /_system/config/apimgt/applicationdata/tenant-conf.json as the location and click Go to browse the registry and locate the required resource.
  4. Update the RESTAPIScopes JSON field by adding custom_role to the Roles field under the corresponding scope Name fields as shown below.
```
{
    "Name": "apim:api_publish",
    "Roles": "admin,Internal/publisher,custom_role"
},
{
    "Name": "apim:api_view",
    "Roles": "admin,Internal/publisher,Internal/creator,Internal/analytics,custom_role"
},
{
    "Name": "apim:api_delete",
    "Roles": "admin,Internal/creator,custom_role"
},
{
    "Name": "apim:subscribe",
    "Roles": "admin,Internal/subscriber,custom_role"
},
{
    "Name": "apim:app_owner_change",
    "Roles": "admin,custom_role"
},
    "Name": "apim:app_import_export",
    "Roles": "admin,custom_role"
},
{
    "Name": "apim:api_import_export",
    "Roles": "admin,custom_role"
},
},
    "Name": "apim:app_manage",
    "Roles": "admin,Internal/subscriber,custom_role"
},
```
2. Using API-M Admin Portal.
  1. Log in to the Admin portal (https://<APIM_Host>:<APIM_Port>/admin).
  2. Navigate to Settings > Scope Mapping in Admin portal.
  3. Add custom_role to the Roles field under the corresponding scope Name fields as shown below.
    
    The above screenshot only shows adding the custom_role to the scopes apim:api_publish, api_view and apim:subscribe. But similarly, you should add custom_role to the scopes apim:app_owner_change, apim:app_import_export, apim:api_import_export and apim:app_manage as well.
Restart the server or wait for 15 mins until the registry cache expires.

Minimal Permissions and Scopes Required to Perform API Controller Operations¶

As explained in the above section, you can create any user with a custom role to perform operations using the API Controller. But if you want that user to perform some of the API Controller operations (not all) you can refer the below table and assign the permissions/scopes accordingly for that role.

Operation	Minimal Permissions	Minimal Scopes
add-env	-	-
remove-env	-	-
list env	-	-
login	API Create or API Publish or API Subscribe	-
logout	API Create or API Publish or API Subscribe	-
list apis	API Create or API Publish or API Subscribe	apim:api_view
delete api	API Create	apim:api_delete, apim:api_view
change-status api	API Publish	apim:api_publish, apim:api_view
import-api	API Create to import an API in CREATED state, Both API Create and API Publish to import an API in PUBLISHED state	apim:api_import_export
import-api with --update	API Create to import an API in CREATED state, Both API Create and API Publish to import an API in PUBLISHED state	apim:api_import_export, apim:api_view
export-api	-	apim:api_import_export
export-apis	-	apim:api_import_export, apim:api_view
list apps	-	apim:app_owner_change
delete app	API Subscribe	apim:subscribe, apim:app_manage,, apim:app_owner_change
import-app	API Subscribe	apim:app_import_export
export-app	-	apim:app_import_export
get-keys	API Subscribe	apim:api_view, apim:subscribe
