Support

Incredibly helpful Slack channel full of all levels of developers and some ServiceNow staff as well. Go here first.

ServiceNow's official support. Very helpful, although you need a login to get here.

A good resource, although not as quick and interactive as Slack.

Go here to manage your personal instance and to get information on the various APIs as well as training.

ServiceNow docs site. Most current documentation.

Legacy ServiceNow site, although a lot of this information is still correct and will show in Google searches.

Unofficial Docs for Service Portal which are pretty close to the Docs site, but perhaps updated more frequently.
