What Capabilities Does Nelio A/B Testing Use?
Nelio A/B Testing uses WordPress capabilities to control which users can create tests, manage running tests, view results, modify settings, and manage the site’s subscription.
By default:
- Administrators have access to all Nelio A/B Testing features.
- Editors can create and manage most tests, but don’t have access to administrative settings or subscription management.
If you need more control, you can use a role management plugin to grant specific capabilities to existing roles or create custom roles for your team.
Available Capabilities
Nelio A/B Testing defines the following capabilities.
Create, Edit, and Delete Tests
These capabilities allow users to create, edit, and delete tests.
| Capability | Description |
|---|---|
edit_nab_experiments | Create and edit tests |
edit_nab_php_experiments | Create and edit PHP Tests. |
delete_nab_experiments | Delete tests |
⚠️ Note: PHP Tests allow arbitrary PHP code to be executed. Only grant edit_nab_php_experiments to trusted users with WordPress development experience.
Manage Running Tests
These capabilities control the lifecycle of tests.
| Capability | Description |
|---|---|
start_nab_experiments | Start tests |
stop_nab_experiments | Stop tests |
pause_nab_experiments | Pause running tests |
resume_nab_experiments | Resume paused tests |

manage_nab_options | Modify Nelio A/B Testing settings. |
Manage the Subscription
| Capability | Description |
|---|---|
manage_nab_account | View and manage the site’s subscription and account information. |
Creating Custom Roles
If you want different team members to have different responsibilities, you can create custom WordPress roles using a role management plugin such as User Role Editor.
For example, you might create an A/B Testing Manager role that can:
- create and edit tests;
- start, pause, resume, and stop tests; and
- view test results.
At the same time, you could prevent those users from:
- modifying plugin settings;
- managing the subscription; or
- creating PHP Tests.
This lets marketing teams run tests while keeping administrative and development tasks restricted to trusted users.
For example, in the following image we have created a new “author in Nelio A/B Testing” role to which we have added test creation and viewing capabilities:
Assigning Capabilities to Individual Users
Instead of creating a new role, many role management plugins also let you grant capabilities directly to individual users.
This is useful when only a small number of users need additional permissions.
Best Practices
We recommend following the principle of least privilege:
- Grant only the capabilities users need.
- Restrict PHP Test creation to experienced developers.
- Limit plugin settings and subscription management to Administrators.
- Review custom roles periodically as your team evolves.
