Overview
API keys authenticate requests to the Telemetron REST API and MCP server. Each organization has a single API key that can be used across all API integrations, including telemetry ingestion, MCP connections, and direct API calls.Prerequisites
- Admin access to your Telemetron organization
Setup

Go to Settings > Integrations. Your API key is displayed in the Developer section of the page.
Configuration
Using Your API Key
Include the API key in thex-api-key header for all REST API requests:
Regenerating Your API Key
If your API key is compromised or you need to rotate it:- Go to Settings > Integrations
- Click Regenerate Key
- Confirm the action
- AWS IoT Core Terraform configuration
- MCP server connections
- Custom API tool configurations
- Any scripts or services calling the Telemetron API
How It Works
The API key identifies and authenticates your organization when making requests to the Telemetron API. Every API request must include a valid key — requests without a key or with an invalid key receive a401 Unauthorized response.
Troubleshooting
| Issue | Resolution |
|---|---|
| 401 Unauthorized responses | Verify the API key is correct and has not been regenerated. Copy the current key from Settings > Integrations. |
| Key not appearing on the page | Ensure you have admin access to the organization. Contact your organization admin if needed. |
| Integrations broken after regeneration | Update the API key in all services and integrations that reference it. The old key is permanently invalidated. |
