Currently the 6Clicks Zapier integration has limited actions available.

• Create Issue or Incident - This is available as an action in Zapier but the response returned is limited. I can see that the issues-api/1.0/issues can return more things after creation

• Get/Update Issue or Incident - Currently there isn't a way to get or update an existing Issue or Incident in Zapier

• Custom API Request - Some Zapier integrations have this option like Slack and Atlassian. It allows API request to any of the rest endpoint with the authentication already handled by the Integration. For example this could open up all of the 6Click Developer API endpoints to Zapier.
