Zapier allows you to connect web apps without any development work through automations called Zaps.
Use a Zap so that an action in Whattime, like a new scheduled event, automatically triggers a corresponding action in another app, such as Keap, Slack, Marketo, Google Sheets, Trello and hundreds more!
How to setup Zaipier
Log into your Zapier account and create a new Zap.
Select WhatTime as your Trigger app. Also choose the Trigger.
Select the corresponding Action app and Action.
Click Continue. When prompted, name your connection and then enter your Unique API Key.
