Connect Beehiiv to Mercury
When New subscriber to publication fires in Beehiiv, your agent runs Add customer in Mercury. 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
Beehiiv and Mercury, answered
What can start an automation from Beehiiv?
Any of Beehiiv's 8 triggers in the catalog, including New subscriber to publication, New unsubscriber to publication, List automations and List newsletter lists. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Mercury when something happens in Beehiiv?
Any of Mercury's 17 actions, including Send money, Update recipient, Update transaction and Add customer. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Mercury to Beehiiv?
Mercury has no triggers in the catalog today, so automations start in Beehiiv. If you need the other direction, ask: your agent reads Mercury's API documentation and adds it.
Do I have to build a connector for Beehiiv or Mercury?
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 Beehiiv and Mercury 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.
