Features are reusable building blocks that define the capabilities you sell. Create a feature once and add it to multiple plans with different configurations.

Feature types

Type	Description	Examples
Boolean	On/off access to a capability	SSO, Custom Branding, Priority Support
Metered	Usage-based with included amounts	API Calls, Storage GB, Emails Sent
Seats	Per-user licenses	Editor Seats, Admin Seats, Viewer Seats

Consumption is defined at the plan level, not the feature level. When you add a feature to a plan, you specify how much is included, whether there's overage, and at what price.

Create features in the dashboard

Go to Features and click Create Feature. Every feature needs a Name (customer-facing) and a Code (internal identifier for the SDK, e.g., api_calls). Feature codes only accept lowercase letters, numbers, and underscores (^[a-z0-9_]+$) and must be unique within your organization.

Metered features also require an Event Code and Unit Name (e.g., "calls", "GB"). Seat features optionally accept a Seat Type (e.g., "Editor", "Admin").

Check feature access

Gate features based on the customer's plan.

const { data } = await commet.featureAccess.get({
  code: 'custom_branding',
  customerId: 'user_123',
})

if (!data.allowed) {
  redirect('/upgrade')
}

response = commet.feature_access.get(
    'custom_branding',
    customer_id='user_123',
)

if not response.data.allowed:
    redirect('/upgrade')

result, err := client.FeatureAccess.Get(ctx, "custom_branding", &commet.GetFeatureAccessParams{
    CustomerID: "user_123",
})
if err != nil {
    return err
}

if !result.Data.Allowed {
    // redirect to upgrade
}

ApiResponse<FeatureLookup> result = commet.featureAccess()
        .get("custom_branding", GetFeatureAccessParams.builder("user_123").build());

if (!result.getData().allowed()) {
    // redirect to upgrade
}

$result = $commet->featureAccess->get('custom_branding', 'user_123');

Get feature details

Returns usage numbers, limits, and overage info.
