Questions
Membrain and TaxJar, answered
What can start an automation from Membrain?
Any of Membrain's 22 triggers in the catalog, including Account Growth Project Created, Account Growth Project Moved to Stage, Activity Created and Company Created. Describe the moment in plain language and your agent picks the right one.
What can your agent do in TaxJar when something happens in Membrain?
Any of TaxJar's 20 actions, including Create a Customer, Create an Order Transaction, Create a Refund Transaction and Update a Customer. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from TaxJar to Membrain?
TaxJar has no triggers in the catalog today, so automations start in Membrain. If you need the other direction, ask: your agent reads TaxJar's API documentation and adds it.
Do I have to build a connector for Membrain or TaxJar?
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 Membrain and TaxJar 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.
