| **Common Causes**             | When you use an incorrect secret for more than 5 attempts, it can trigger security protocols that may lock your account to prevent unauthorized access.                                                              |
| **Troubleshooting Steps**     | If your account (including your partnerId and secret associated with your integration) is locked due to security reasons as a result of multiple failed attempts, contact customer support to unlock your account. ​ |
