Harbor is an API. You interact with it three ways: curl, any HTTP client, or the harbor CLI (useful for local development and scripting).

1. Get an API key

Sign up at harbor.example and create a project. In the project dashboard, create a live and a test API key. Live keys start with hk_live_, test keys start with hk_test_. Store them in your secret manager — there is no way to retrieve a lost key, only to rotate it.

2. Install the CLI (optional)

npm i -g @harbor/cli
harbor login

The CLI is not required — it just makes local development less painful by tunneling deliveries to your laptop. See Local testing.

3. Verify

curl https://api.harbor.example/v1/destinations \
  -H "Authorization: Bearer hk_test_your_test_key"

You should get back an empty paginated response:

{ "data": [], "next_cursor": null }

If you get a 401, the key is wrong or you forgot the Bearer prefix. If you get a 403, the key is for a different project or environment.

Next: send your first webhook in the Quickstart.
