We have migrated the really handy Web API Step Handler from Simego Online into DS3 Automation Server (Ouvvi) this allows you to setup calls to Web Applications that have documented API's. such as other notification systems.
For example configuring the Web API Step to send messages to your mobile devices based on the Pushover system is easy as setting up the request like this below.
You can also use this to Test your Web API's and ensure that the API's are working as intended. Or perhaps to use this as a Queue Relay Broker service to integrate application messages.
The Web API allows you to control the request details and validate the response so you can test to ensure the response is what you expected.
