Octopus Feature Toggles rely on [OpenFeature](https://openfeature.dev/) as the client SDK.

Configure OpenFeature to use the [Octopus Provider](/docs/feature-toggles/providers).

The Octopus OpenFeature Provider requires a client identifier when instantiated. This is a [JWT](https://jwt.io/introduction) which specifies the Octopus Project, Environment, and Tenant (if applicable). This tells the Octopus Feature Toggle service which set of toggles to evaluate.

You can additionally target specific [Tenants](#tenants) or [User Segments](#segments).

## Providers {#providers}

Below are the Octopus OpenFeature provider SDKs currently available:

### Server SDKs
- [.NET](https://github.com/OctopusDeploy/openfeature-provider-dotnet)
- [Java](https://github.com/OctopusDeploy/openfeature-provider-java)

### Web SDKs
- [TypeScript/JavaScript](https://github.com/OctopusDeploy/openfeature-provider-ts-web)

Configuring the providers is documented in the README files in the repositories.

## Segments {#segments}

Segments allow enabling a toggle for a subset of users.

Segments are key/value pairs, and are supplied by your applications via the [OpenFeature EvaluationContext](https://openfeature.dev/docs/reference/concepts/evaluation-context).


Common segment examples include:

- Specific users. e.g. `user-id/123456`
- Specific accounts. e.g. `account-id/123456`
- License types. e.g. `license-type/free`
- Geographic regions. e.g. `region/eu`
- Rollout rings. e.g. `ring/early-adopter`

The Evaluation Context can be supplied at different points in your application, for example:

- On start-up
- During each web request
- At the evaluation site

The following example shows adding a key/value to the evaluation context in C#.

```cs
// The client would be injected by IoC in many cases
var client = OpenFeature.Api.Instance.GetClient();
// The following is hard-coded, whereas a real-world use would set this dynamically
client.SetContext(EvaluationContext.Builder().Set("license-type", "free").Build());
```

Segments can then be configured for Environments on the Feature Toggle in Octopus.

![Add Segment](/docs/img/feature-toggles/segment-add.png)

A Toggle evaluation will match on segments if the evaluation context matches at least one segment for each key.

Some examples:

|Segments | Evaluation Context | Result |
|-----------|--------------------|--------|
| `user-id/123456` | `user-id/123456` | `On` |
| `user-id/123456` | `user-id/789383` | `Off` |
| `license-type/free` `region/Asia` `region/EU` | `license-type/free` `region/Asia` | `On` |
| `license-type/free` `region/Asia` `region/EU` | `license-type/free` `region/US` | `Off` |

## Tenants {#tenants}

If your Project uses [Tenants](/docs/tenants/), then Toggles may be enabled for subsets of your Tenants.

The options for configuring a Feature Toggle for Tenants are:

- All Tenants
- Specific Tenants Included
- % of Tenants
- Specific Tenants Excluded

For example, the configuration shown below will result in the Toggle evaluating as `On` for 10% of Tenants, always including `Acme` and never including `Cyberdyne Systems`.

![Tenanted Rollout](/docs/img/feature-toggles/tenant-rollout.png)
You can additionally control rollout within an environment. See [Feature Toggle targeting](/docs/feature-toggles/targeting) for more information.

## Default Values {#default-values}

Toggle default values are configured both on the Toggle in Octopus, and at the evaluation site in your client application. It's important to understand how these interact.
