Learn how to authenticate with the Arcadia API using HTTP Basic authentication with your appId and appKey credentials.
Authenticate Arcadia Signal API requests with HTTP Basic authentication using your appId and appKey.
Basic authentication
Signal API requests use HTTP Basic authentication.
Use your credentials as follows:
| Credential | Basic Auth role |
|---|---|
appId | Username |
appKey | Password |
Most HTTP clients can send Basic Auth credentials directly. If your client requires a header, construct an Authorization: Basic header from the Base64-encoded appId:appKey pair.
Validate credentials
Use the Echo Authenticate endpoint to validate that your appId and appKey are valid before calling more complex endpoints.
