You need to be authenticated for all API requests. You can generate a project specific API key in the form of a JWT token in your Project Settings dashboard. Choose the
DAML Party that will authorize the requests and then copy the token to your clipboard in the format of your choice.
Add the JWT token to all requests as a Header parameter.
Authorization: Bearer eyJhbGciOiJSUzI1NiIsImtpZCI6ImRhYmwtMjAxOS0wOC0wNy0xNz...
Nothing will work unless you include this JWT Token.
