Connect GoHighLevel and Mattermost
When New or updated contact fires in GoHighLevel, your agent runs Post Message in Mattermost, or New Channel in Mattermost to Create contact in GoHighLevel. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Questions
GoHighLevel and Mattermost, answered
What can start an automation from GoHighLevel?
Any of GoHighLevel's 1 trigger in the catalog, including New or updated contact. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Mattermost when something happens in GoHighLevel?
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 GoHighLevel?
Yes. When something happens in Mattermost, your agent can act in GoHighLevel too. This page covers both directions: Mattermost's triggers and GoHighLevel's actions are listed here as well.
Do I have to build a connector for GoHighLevel 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 GoHighLevel 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.
