Integration
Connect HelpCrunch and Lettr
When Chat Assignee Updated fires in HelpCrunch, your agent runs Add contact in Lettr, or New email event in Lettr to Add Customer Event in HelpCrunch. 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
HelpCrunch and Lettr, answered
What can start an automation from HelpCrunch?
Any of HelpCrunch's 8 triggers in the catalog, including Chat Assignee Updated, Chat Status Updated, Customer Email Updated and Customer Tags Updated. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Lettr when something happens in HelpCrunch?
Any of Lettr's 26 actions, including Create campaign, Create webhook, Send campaign and Send Email. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Lettr to HelpCrunch?
Yes. When something happens in Lettr, your agent can act in HelpCrunch too. This page covers both directions: Lettr's triggers and HelpCrunch's actions are listed here as well.
Do I have to build a connector for HelpCrunch or Lettr?
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 HelpCrunch and Lettr 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.
