| `DD_API_KEY` | The environment variable with your Datadog API key, in plaintext. **One** key environment variable is required. See [serverless CLI environment variables][7]. |
| `DD_KMS_API_KEY` | The environment variable with your Datadog API key, using KMS. **One** key environment variable is required. See [serverless CLI environment variables][7]. |
| `DD_API_KEY_SECRET_ARN` | The environment variable with your Datadog API key, using an AWS Secrets Manager secret. **One** key environment variable is required. See [serverless CLI environment variables][7]. |
| `DD_API_KEY_SECRET_RELOAD_INTERVAL` | Only applicable when `DD_API_KEY_SECRET_ARN` is set. The interval (in seconds) at which to periodically reload the API key from AWS Secrets Manager. The reload is triggered lazily when the API key is needed for a flush and the interval has elapsed. If unset or `0`, the secret is loaded once and never reloaded. Available for version 88+ of the Datadog Lambda Extension. **Best practice for key rotation:** when rotating your API key, keep the old key valid for a grace period after creating the new one, and set this interval to a value shorter than that grace period. This helps ensure the extension always reloads the new key before the old one expires. |
