Questions
Sellsy and Magic Heidi, answered
What can start an automation from Sellsy?
Any of Sellsy's 9 triggers in the catalog, including New Company, New Contact, New Opportunity and New Task. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Magic Heidi when something happens in Sellsy?
Any of Magic Heidi's 5 actions, including Create Expense, Create Invoice, Create Temporary Invoice (Not Saved to Your Account) and Get Expense. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Magic Heidi to Sellsy?
Magic Heidi has no triggers in the catalog today, so automations start in Sellsy. If you need the other direction, ask: your agent reads Magic Heidi's API documentation and adds it.
Do I have to build a connector for Sellsy or Magic Heidi?
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 Sellsy and Magic Heidi 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.
