Integration
Connect BigMailer and Mews
When New Contact fires in BigMailer, your agent runs Add Customer File in Mews, or New Accounting Item in Mews to Add/Update Contact in BigMailer. 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
BigMailer and Mews, answered
What can start an automation from BigMailer?
Any of BigMailer's 1 trigger in the catalog, including New Contact. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Mews when something happens in BigMailer?
Any of Mews's 29 actions, including Create Availability Block, Create Company, Create Customer and Create New Task. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Mews to BigMailer?
Yes. When something happens in Mews, your agent can act in BigMailer too. This page covers both directions: Mews's triggers and BigMailer's actions are listed here as well.
Do I have to build a connector for BigMailer or Mews?
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 BigMailer and Mews 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.
