--- title: Authentication sidebarTitle: Authentication description: Authenticating with the Trigger.dev management API --- There are two methods of authenticating with the management API: using a secret key associated with a specific environment in a project (`secretKey`), or using a personal access token (`personalAccessToken`). Both methods should only be used in a backend server, as they provide full access to the project. There is a separate authentication strategy when making requests from your frontend application. See the [Frontend guide](/frontend/overview) for more information. This guide is for backend usage only. Certain API functions work with both authentication methods, but require different arguments depending on the method used. For example, the `runs.list` function can be called using either a `secretKey` or a `personalAccessToken`, but the `projectRef` argument is required when using a `personalAccessToken`: ```ts import { configure, runs } from "@trigger.dev/sdk/v3"; // Using secretKey authentication configure({ secretKey: process.env["TRIGGER_SECRET_KEY"], // starts with tr_dev_ or tr_prod_ }); function secretKeyExample() { return runs.list({ limit: 10, status: ["COMPLETED"], }); } // Using personalAccessToken authentication configure({ secretKey: process.env["TRIGGER_ACCESS_TOKEN"], // starts with tr_pat_ }); function personalAccessTokenExample() { // Notice the projectRef argument is required when using a personalAccessToken return runs.list("prof_1234", { limit: 10, status: ["COMPLETED"], projectRef: "tr_proj_1234567890", }); } ``` Consult the following table to see which endpoints support each authentication method. | Endpoint | Secret key | Personal Access Token | | ---------------------- | ---------- | --------------------- | | `task.trigger` | ✅ | | | `task.batchTrigger` | ✅ | | | `runs.list` | ✅ | ✅ | | `runs.retrieve` | ✅ | | | `runs.cancel` | ✅ | | | `runs.replay` | ✅ | | | `envvars.list` | ✅ | ✅ | | `envvars.retrieve` | ✅ | ✅ | | `envvars.upload` | ✅ | ✅ | | `envvars.create` | ✅ | ✅ | | `envvars.update` | ✅ | ✅ | | `envvars.del` | ✅ | ✅ | | `schedules.list` | ✅ | | | `schedules.create` | ✅ | | | `schedules.retrieve` | ✅ | | | `schedules.update` | ✅ | | | `schedules.activate` | ✅ | | | `schedules.deactivate` | ✅ | | | `schedules.del` | ✅ | | ### Secret key Secret key authentication scopes the API access to a specific environment in a project, and works with certain endpoints. You can read our [API Keys guide](/apikeys) for more information. ### Personal Access Token (PAT) A PAT is a token associated with a specific user, and gives access to all the orgs, projects, and environments that the user has access to. You can identify a PAT by the `tr_pat_` prefix. Because a PAT does not scope access to a specific environment, you must provide the `projectRef` argument when using a PAT (and sometimes the environment as well). For example, when uploading environment variables using a PAT, you must provide the `projectRef` and `environment` arguments: ```ts import { configure, envvars } from "@trigger.dev/sdk/v3"; configure({ secretKey: process.env["TRIGGER_ACCESS_TOKEN"], // starts with tr_pat_ }); await envvars.upload("proj_1234", "dev", { variables: { MY_ENV_VAR: "MY_ENV_VAR_VALUE", }, override: true, }); ```
