# AppExchange Partners, Upgrade SSO Claim v2

**note:** These instructions apply only to multi-tenant applications, such as apps on AppExchange.

Ensure that your multi-tenant applications use the tenant-specific endpoints returned in the Claim v2 JWT for new customers on an instance other than S1 through S10. For customers on S1 through S10, your multi-tenant applications continue to make calls against the legacy ExactTarget endpoints.

To support customers using tenant-specific endpoints, your app must:

- Use the SSO Claim v2 JSON Web Token, or JWT, found in the App component. To update your app, contact your Partner Account Manager and see [Upgrade SSO Claim Version](https://developer.salesforce.com/docs/marketing/marketing-cloud/guide/upgrade-sso.md).
- Correctly consume the Claim v2 JWT with tenant-specific endpoints.

For REST API requests, make sure that your app constructs its requests using the account-specific values for the `authEndpoint` and the `apiEndpointBase` parameters.

For SOAP API requests, make a REST call to request an access token. Next, issue a [GET request to the platform/v1/endpoints endpoint](https://developer.salesforce.com/docs/marketing/marketing-cloud/references/mc_rest_platform?meta=Get%2BEndpoints) to find the SOAP endpoint for your account.
