# Feature flags API **(FREE SELF)**
|
|
|
|
This API is for managing Flipper-based [feature flags used in development of GitLab](../development/feature_flags/index.md).
|
|
|
|
All methods require administrator authorization.
|
|
|
|
Notice that currently the API only supports boolean and percentage-of-time gate
|
|
values.
|
|
|
|
## List all features

## Set or create a feature
|
|

|
it's created. The value can be a boolean, or an integer to indicate
|
|
percentage of time.
|
|
|
|
```plaintext

|
|
| `name` | string | yes | Name of the feature to create or update |
|
|
| `value` | integer/string | yes | `true` or `false` to enable/disable, or an integer for percentage of time |
|
