# Update credential pool

PATCH https://api.prolific.com/api/v1/credentials/{credential_pool_id}/
Content-Type: application/json

Add new credentials to an existing credential pool. This operation is additive - new credentials are appended to the existing pool rather than replacing them. The credentials service validates that no duplicate usernames exist.
The credentials are provided as a CSV string where each line contains a username and password separated by a comma (e.g., "user4,pass4\nuser5,pass5").
