Obtaining an API Key

Go to Administration > Service Integration.
On the API Access tab, click Add to generate a key.
The API Key is the global unique identifier for your application to authenticate its access to Trend Micro Email Security. It must be used together with the administrator account that created it. A new API Key is enabled by default.
If you want to change your API Key later on, click Add to generate a new key and use the new key in your requests. You can click the toggle button under Status to disable the old key or delete it if both of the following conditions are met:
- Requests can be sent successfully with the new key.
- The old key is not used by any other applications that have access to Trend Micro Email Security.
A maximum of two API Keys are allowed at a time.
Important:
The API Key allows your application to communicate with Trend Micro Email Security. Keep the API Key private.
