# Update credential pool

`PATCH /api/v1/credentials/{credential_pool_id}/`

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").

## Path parameters

- `credential_pool_id` string, required
