Questions
Returnless and ShipEngine, answered
What can start an automation from Returnless?
Any of Returnless's 2 triggers in the catalog, including Request Created and Return Created. Describe the moment in plain language and your agent picks the right one.
What can your agent do in ShipEngine when something happens in Returnless?
Any of ShipEngine's 14 actions, including Update shipment, Add batch, Add label and Add shipment. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from ShipEngine to Returnless?
ShipEngine has no triggers in the catalog today, so automations start in Returnless. If you need the other direction, ask: your agent reads ShipEngine's API documentation and adds it.
Do I have to build a connector for Returnless or ShipEngine?
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 Returnless and ShipEngine 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.
