To get the Kratos user ID after the Ory Hydra consent flow, you need to follow these steps: 1. Complete the OAuth2 authorization code flow with Hydra, including the consent step. 2. After successful authentication and consent, you'll receive an access token from Hydra. 3. Use this access token to make a request to the Hydra token introspection endpoint or the userinfo endpoint (if using OpenID Connect). 4. The response from these endpoints should include information about the authenticated user, including the Kratos user ID. However, it's important to note that the exact implementation details for retrieving the Kratos user ID after the Hydra consent flow are not explicitly provided in the given knowledge sources. The integration between Hydra and Kratos for this specific use case is not clearly documented in the provided information. To get more accurate and detailed information about retrieving the Kratos user ID after the Hydra consent flow, you may need to consult additional Ory documentation or reach out to Ory support for specific guidance on integrating Hydra and Kratos in this scenario. For general information about the OAuth2 authorization code flow with Hydra, you can refer to the [OAuth2 authorization code flow documentation](https://www.ory.sh/docs/oauth2-oidc/authorization-code-flow#modifying-the-authorization-code-flow), which provides details on how to modify the flow to include additional scopes like

offline_access

and

openid
