# What Happens If I Regenerate My API Key on SMSGatewayCenter?

**Regenerating an API key** on **SMSGatewayCenter** updates your authentication credentials, which can impact existing integrations. Here’s what happens and how to manage it:

## **Consequences of Regenerating an API Key**

- **Invalidates the Old Key**: The previous API key will no longer work, and any API requests using it will fail.
- **Disrupts Integrations**: Existing integrations (e.g., CRM systems, apps) using the old key will stop functioning until updated with the new key.

### **Steps to Manage the Transition**

- **Regenerate the Key**: Follow the steps to regenerate your API key in the *Generate API Key Settings* section (see FAQ on [regenerating API keys](https://www.smsgatewaycenter.com/blog/kb/regenerate-api-key/)).
- **Copy the New Key**: Note down the newly generated API key (it may be masked for security, so use the reveal functionality).
- **Update Integrations**: Replace the old API key with the new one in all your applications or systems using the [SMSGatewayCenter API](https://www.smsgatewaycenter.com/developer-api/).
  - Example: Update your API request header to `Authorization: Bearer new_api_key`.
- **Test the New Key**: Make a test API request to ensure the new key works.

#### **Best Practices**

- Schedule the regeneration during a low-activity period to minimize disruption.
- Notify your development team in advance to ensure all integrations are updated promptly.

Properly managing the transition after regenerating your API key ensures uninterrupted API usage on **SMSGatewayCenter**. For assistance, contact our support team.
