If you already have a vWork account, you can create your own API Key here on the integrations page.
If you do not yet have a vWork account, you can create a free trial vWork account here on the signup page.
Version 5 of the API is our current version and should be used when creating a new integration.
There are three sets of documentation for v5. The base documentation covers everything except jobs (eg: users, customers).
The Jobs documentation covers creating and managing jobs from scratch.
The Templated Jobs documentation covers creating jobs from templates. This is the best option if you need to create jobs in vWork and requires the least coding.
