Connect Reply to Synthflow AI
When New Email Opened fires in Reply, your agent runs Create Assistant in Synthflow AI. 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.
What do you want Reply and Synthflow AI to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Questions
Reply and Synthflow AI, answered
What can start an automation from Reply?
Any of Reply's 7 triggers in the catalog, including New Email Opened, New Emails Sent, New Link Clicked and New Person Bounce. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Synthflow AI when something happens in Reply?
Any of Synthflow AI's 25 actions, including Create Assistant, Create Booking Calcom Action, Create Booking GHL Action and Create Call. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Synthflow AI to Reply?
Synthflow AI has no triggers in the catalog today, so automations start in Reply. If you need the other direction, ask: your agent reads Synthflow AI's API documentation and adds it.
Do I have to build a connector for Reply or Synthflow AI?
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 Reply and Synthflow AI 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.
