Connect Castmagic to LINE Messaging API
When New Recording fires in Castmagic, your agent runs Send multicast message in LINE Messaging API. 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
Castmagic and LINE Messaging API, answered
What can start an automation from Castmagic?
Any of Castmagic's 1 trigger in the catalog, including New Recording. Describe the moment in plain language and your agent picks the right one.
What can your agent do in LINE Messaging API when something happens in Castmagic?
Any of LINE Messaging API's 5 actions, including Send multicast message, Send push message, Send reply message and Get user profile. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from LINE Messaging API to Castmagic?
LINE Messaging API has no triggers in the catalog today, so automations start in Castmagic. If you need the other direction, ask: your agent reads LINE Messaging API's API documentation and adds it.
Do I have to build a connector for Castmagic or LINE Messaging API?
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 Castmagic and LINE Messaging API 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.
