Questions
Casting42 and Mattermost, answered
What can start an automation from Casting42?
Any of Casting42's 6 triggers in the catalog, including New Casting, New Contact, New Talent and Updated Casting. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Mattermost when something happens in Casting42?
Any of Mattermost's 26 actions, including Create Channel, Post Message, Update channel and Update Post. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Mattermost to Casting42?
Yes. When something happens in Mattermost, your agent can act in Casting42 too. This page covers both directions: Mattermost's triggers and Casting42's actions are listed here as well.
Do I have to build a connector for Casting42 or Mattermost?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Casting42 and Mattermost without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
