DHD REST API
The DHD REST API comes with Firmware Version 9.1 & Web Apps version 2.0. It is meant to provide easy access to useful functionalities of the console and is designed primarily to write. Reading values is only possible for global labels. This is to prevent polling.
DHD REST API is restricted to an average of one request per second, but can handle bursts of up to 10 requests per second. After such a burst of e.g. 10 requests, you will have to wait 10 seconds before the server accepts any new calls. If you have a Burst of e.g. 5 requests, you will have to wait 5 seconds. During this 'grace period', the server will respond with code 423 (Locked).
REST API (system) will be reduced in its feature set, as it would introduce duplicate functions as the new control API.
The following calls are deprecated within firmware version 10.2 and will be removed soon:
- Load Mixer Snapshot
- Save Mixer Snapshot
- Load Channel Snapshot
- Save Mixer Snapshot
- Upload Mixer Snapshot
- Download Mixer Snapshot
- Upload Channel Snapshot
- Download Channel Snapshot
Note
All examples can vary on different platforms and shell / terminal environtments. Please check for the correct syntax on your environment.
REST API must be enabled in Toolbox, [Device Node] > Web Apps Tab, REST API checkbox.

Responses
The server will respond with a status 200 and a JSON object. The JSON object contains the received values such as some data required by DHD audio for debugging. If something on your request goes wrong, the JSON object will contain an Error entry.
If the server doesn't respond with status code 200:
- Status code
423 (Locked): the REST API is locked because of too many requests (more than 10 per minute) - Status code
405 (Method Not Allowed):- check if REST API checkbox is enabled within Toolbox [Device Node] >
