Connect AfterShip and Lettr
When New Tracking fires in AfterShip, your agent runs Add contact in Lettr, or New email event in Lettr to Create Tracking in AfterShip. 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
AfterShip and Lettr, answered
What can start an automation from AfterShip?
Any of AfterShip's 3 triggers in the catalog, including New Tracking, Tracking Updated and Tracking Delivered. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Lettr when something happens in AfterShip?
Any of Lettr's 23 actions, including Create campaign, Send campaign, Send Email and Send Email Template. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Lettr to AfterShip?
Yes. When something happens in Lettr, your agent can act in AfterShip too. This page covers both directions: Lettr's triggers and AfterShip's actions are listed here as well.
Do I have to build a connector for AfterShip or Lettr?
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 AfterShip and Lettr 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.
