# Create credential pool

POST https://api.prolific.com/api/v1/credentials/
Content-Type: application/json

Create a new workspace-level credential pool. Credential pools contain username/password pairs that can be assigned to participants when they start a study. This allows researchers to provide pre-provisioned credentials for third-party platforms.
The credentials are provided as a CSV string where each line contains a username and password separated by a comma (e.g., "user1,pass1\nuser2,pass2").
