Environments and Endpoints When you login to your Project there’s a section called “Environments & API Keys”.

​
Environments

Each environment has an API Key associated with it. This API Key is used to authenticate your Jobs with the Trigger.dev platform. The API Key you use for your Client is how we know which environment to run your code against: 
export const client = new TriggerClient({
  id: "nextjs-example",
  //this environment variable should be set to your DEV API Key locally,
  //and your PROD API Key in production
  apiKey: process.env.TRIGGER_API_KEY!,
});

​
Development

The DEV environment should only be used for local development. It’s where you can test your Jobs before deploying them to servers.
Scheduled Triggers do not trigger Jobs in the DEV Environment. When you're working locally you should use the Test feature to trigger any scheduled Jobs.

​
Staging

The STAGING environment is useful for testing your Jobs against your staging server, if you have one. STAGING works identically to PROD.

​
Production

The PROD environment is where your Jobs will run in production. It’s where you can run your Jobs against real data.

​
Endpoints

An Endpoint is a URL on your server that Trigger.dev can connect to. This URL is used to register Jobs, start them and orchestrate runs and retries. DEV has multiple endpoints associated with it – one for each team member. This allows each team member to run their own Jobs, without interfering with each other. All other environments have just a single endpoint (with a single URL) associated with them.
