The OpsDash SaaS version includes APIs to report custom metrics, query alert status and perform various other operations. For example, you can display the current alert status as shown in OpsDash here, into your own business dashboard like Dashing, by making use of the Status API.
We're in the process of adding more API calls, so that you can automate more of your monitoring tasks with OpsDash.
The full API reference can be found here: https://www.opsdash.com/apidocs-saas/index.html
Webhooks can be set up to receive alert notifications. You can configure them in the OpsDash UI.
