# Configure STS instances

You configure STS *instances* to perform one or more token transformations. Each instance provides configuration details about how SAML 2.0 and/or OpenID Connect output tokens are encrypted or signed. Deployments that support multiple SAML 2.0 and/or OpenID Connect service providers require multiple STS instances.

When you publish an STS instance, you create an STS instance with a given configuration. You can publish instances using the AM admin UI or the REST API.

When you publish a REST STS instance, AM exposes a REST endpoint for accessing the instance, and the instance is immediately available for use to callers.

|   | The SOAP STS service is deprecated, and will be removed in a future release. Installing instances of this service is not supported. |

## Configure the REST STS

To configure a REST STS instance using the AM admin UI, go to Realms > *Realm Name* > STS > REST STS Instances, and click Add.

See [REST STS configuration properties](sts-configure-rest-properties.html) for detailed information about STS configuration properties.

|   | You can also publish REST STS instances programmatically. AM provides a Publish service, which is a collection of endpoints you can use to publish instances instead of accessing the AM admin UI.For more information, see [Publish REST STS instances](sts-publish-service.html#sts-publish-rest). |
