Each project has two unique API Keys to interface its endpoint programmatically. The API Keys for a specific project can be found in the given project’s dashboard.
Though two are provided, only one is needed to access an endpoint. Either one can be used, and each can be refreshed independently. We give two so that if you'd like to refresh your API key, there will be a second API key that remains valid throughout that entire transition so that there is no need to pause submissions while switching over.
To use an API key, you include header 'authorization: token <YOUR_API_KEY>' in the request.
