FAQ

Common questions about AffiniPay + Smart Sender

Is there a pre-built AffiniPay + Smart Sender automation?

Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches AffiniPay and Smart Sender's public API docs (or your own uploaded docs) and builds a working automation.

Does this require a pre-built AffiniPay or Smart Sender connector?

No. The Agent works whether or not AffiniPay or Smart Sender already has a pre-built connector in Knit's catalog — it researches the real API surface either way.

How long does it take to build?

Minutes to build a first working version, not weeks — you test it against real data before it goes anywhere near production.

How does connecting Smart Sender and AffiniPay help manage paying customers?

Receiving payments in AffiniPay allows you to automatically enroll customers in targeted marketing segments or sync billing profiles with Smart Sender.

Can overdue billing status influence marketing updates?

Yes, when an invoice becomes overdue in AffiniPay, you can automatically add the contact to a payment reminder segment in Smart Sender.
