<@U04UQ68083H> How can i know identity already exist?

To check if an identity already exists in your Ory system, you can use the `listIdentities` method of the Ory API. This method lists all identities in the system. You can call this method using the following endpoint:  ``` GET /admin/identities ```  You need to be authenticated to perform this operation. The authentication method is `oryAccessToken`.  Here is an example of how you can use this method in a command line:  ```bash ory list identities --project $ORY_PROJECT_ID   ```  This command will list all identities in the specified project. You can then check this list to see if the identity you are interested in already exists.  Please note that this information is based on the extracts provided and for more detailed information, you should refer to the [Ory API Reference](<https://www.ory.sh/docs/reference/api>).
