# Create a new active session

`POST /sessions`

Create a new active session for the provided user ID.

**This operation is intended only for use in testing, and is not available for production instances.** If you are looking to generate a user session from the backend,
we recommend using the [Sign-in Tokens](https://clerk.com/docs/reference/backend-api/tag/Sign-in-Tokens#operation/CreateSignInToken) resource instead.
