Use your project-specific Secret API key. Will start with `tr_dev_`, `tr_prod`, `tr_stg`, etc.

You can find your Secret API key in the API Keys section of your Trigger.dev project dashboard.

Our TypeScript SDK will default to using the value of the `TRIGGER_SECRET_KEY` environment variable if it is set. If you are using the SDK in a different environment, you can set the key using the `configure` function.

    import { configure } from "@trigger.dev/sdk";configure({ accessToken: "tr_dev_1234" });
