GroupShare WebHooks Service

WebHooks provide a publish / subscribe model for wiring together Web APIs and services. You can subcribe to GroupShare events and get notified when that event happens, through a callback.

When subscribing to an event you need to provide a callback URI where you want to be notified when the event occurs. When the event occurs an HTTP POST request is sent to your callback URI with information about what happened.

GroupShare WebHooks Service

GroupShare WebHooks Service is implemented as a standalone self hosted Rest API application, that can be run as a Windows Service or in console mode (using --console switch).
The default port that the Rest API self hosted service listens is 41239.

Configuration

Configuration for the WebHooks service is done in Sdl.GroupShare.WebHooksService.exe.config under C:\Program Files\SDL\SDL Server\WebHooks Service (only relevant settings are shown):

<appSettings>
  <add key="RestHostUrl" value="http://+:41239" />
  <add key="MessageQueueHost" value="localhost" />
  <add key="MessageQueueUserName" value="gssvc" />
  <add key="MessageQueueUserPassword" value="u5F/lWdnD+snwvYcjKv/Fg==" />
  <add key="WebHookQueueName" value="GsWebHookQueue" />
  <add key="WebHookQueueDeadLetterName" value="GsWebHookQueueDeadLetter" />
  <add key="WebHookQueueDLXName" value="GsWebHookDlx" />
  <add key="Server" value="gs-test-url.sdltest.com" />
  <add key="serilog:write-to:RollingFile.pathFormat" value="C:\ProgramData\SDL\Service\logs\WebHooks.Log" />
</appSettings>
<connectionStrings>
  <add name="MS_SqlStoreConnectionString" connectionString="Server=(local)\sqlserver2014;Database=SDLSystem;Trusted_Connection=True;" providerName="System.Data.SqlClient" />
</connectionStrings>

Above you can see the configuration used for the service listening port, the RabbitMQ message queue and the database where the web hook registrations will be stored.

RestHostUrl

The host and port setting that the Web Hooks Service will use to listen on.

MessageQueueHost, MessageQueueUserName, MessageQueuePassword

These are configured by GroupShare installer and are needed to consume messages from RabbitMQ.

WebHookQueueName, WebHookQueueDeadLetterName, WebHookQueueDLXName

Used to specify the queues to consume messages from. It would be possible to create new queues with different routing keys. Recommended to leave as it is.

Server

The value of the Server setting will be included in the callback request body, to know the web hook sender of the message. See the "Server" property in each message body.

Supported Filters

You can subscribe to all existing events by using the "*" filter and a single callback handling URL.
The available filter types are as follows:

Sdl.GroupShare.Events.V2.ProjectCreatedEvent
Sdl.GroupShare.Events.V2.PhaseChangeEvent
Sdl.GroupShare.Events.V2.AssignmentEvent
Sdl.GroupShare.Events.V2.CheckOutEvent
Sdl.GroupShare.Events.V2.CheckInEvent
*

Rest API endpoint of WebHooks Service

Interaction with the GroupShare WebHooks Service happens through Rest API calls, secured with bearer tokens (that you get using GS Management Rest API login endpoint).

POST /api/webhooks/registrations

Request information

Parameter	Explanation
WebHookUri	The URI used by GroupShare to do a POST request when the event occurs, that you subscribed to using the filter. WebHookUri query string parameters Use the 'noecho' parameter to register a web hook without endpoint verification. If you don't supply this parameter GroupShare will do endpoint verification to check that the supplied endpoint exists i.e. upon receiving the web hook registration request GroupShare will do a GET request to the WebHookUri. If this is desired then you need to send also an echo query string parameter and when receiving the verification request you need to return the exact content of that parameter in plain text. Otherwise GroupShare will reject webhook registration with a message: "WebHook verification failed. Please ensure that the WebHook URI is valid and that the endpoint is accessible."
Secret	A shared secret, created as part of subscribing to events. The receiver uses this shared secret to validate that the request comes from GroupShare. The WebHook secret key parameter must be between 32 and 64 characters long.
Filters	Array of filters that you are interested in subscribing. You can subscribe to multiple events at once, in this case your callback needs to know how to handle the different callback data. Or subscribe to events one by one with different callback endpoints.

Receiving WebHooks Notifications (callbacks)

After a WebHook URI was registered for a certain event you will get callbacks when that event occurs. The callback is a POST request.

Request headers

Parameter	Explanation
ms-signature	An SHA 256 signature on the request body. The signature uses the secret key from the WebHook registration. Example: "sha256=275F1BFF2327BBAF7F61A1BB1920BAC0A5295C2F4C78312345247031D37A8031"
X-Correlation-ID	A correlation guid - this is the actual id of a webhook item (from GroupShare)

Request body
