# About Service Slugs

In the context of Wix Bookings, a slug is a user-friendly and unique identifier
assigned to each service. It is designed to be easily readable and consists only
of lowercase letters, digits, and hyphens.

## Default slugs

When a service is created, Wix Bookings automatically calculates its `mainSlug`
based on the service name. Any non-alphanumeric character from the service name
is replaced with a hyphen, then consecutive hyphens are removed. If the
resulting slug would be empty or a single hyphen, it's set to `untitled` instead.

### Sample default slugs

The following table shows some sample default slugs.

| Service name | Default slug |
|---|---|
| `My Service! Name 2023` | `my-service-name-2023` |
| `@@@` | `untitled` |
| `A simple_test` | `a-simple-test` |

### Service name changes

When a service's name changes, Wix Bookings automatically updates `mainSlug`,
unless the service has a custom slug. All past slugs and the current slug are
stored in `service.supportedSlugs`.

## Custom slugs

You can customize a service's slug, for example for SEO purposes. Like default
slugs, custom slugs may include only lowercase letters, digits, and hyphens.

### Set a custom slug
 You can call [Set Custom Slug](https://dev.wix.com/docs/rest/business-solutions/bookings/services/services-v2/set-custom-slug.md)
to customize a service's slug. Once you've set a custom slug, Wix Bookings
doesn't automatically update `mainSlug` whenever the service name changes.
Instead, it adds a default slug based on the new service name to the
`service.supportedSlugs` array.

### Validate a custom slug

You can check if a custom slug contains only supported characters, and isn't
associated with a different service by calling [Validate Slug](https://dev.wix.com/docs/rest/business-solutions/bookings/services/services-v2/validate-slug.md).
