# Testing

To confirm that your integration works correctly, you have several testing options. We now recommend using our new API testing method, while the existing approaches will be gradually deprecated.

## 🆕 Recommended API Testing (No Credits Needed)

    Create test participants: `POST /api/v1/researchers/participants/`
  </Step>

    Publish in test mode: `POST /api/v1/studies/{id}/test-study`
  </Step>

  <Step>
    Complete the study as a test participant
  </Step>

  <Step>
    Approve or reject submissions normally
  </Step>
