Most SignalWire REST API endpoints require authentication using HTTP Basic Auth. HTTP Basic Authentication requires you to send an Authorization header of your Project ID and Authentication Token. This should be supported in almost all HTTP clients.

Each project has its own Project ID and Authentication Tokens you will need to use when making each request to the API. You can find your Project ID and Authentication Tokens in your SignalWire Dashboard.

SignalWire Dashboard


curl \
-u 'YourProjectID:YourAuthToken'

Note that cURL uses the -u option to pass in HTTP Basic Auth credentials to the request. These are your Project ID and Auth Tokens, which you can find in your SignalWire Dashboard.

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
