FAQ

Common questions about Sinch + ZAP POST

Is there a pre-built Sinch + ZAP POST automation?

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

Does this require a pre-built Sinch or ZAP POST connector?

No. The Agent works whether or not Sinch or ZAP POST 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.

New contacts captured in ZAP POST can instantly be added as email subscribers in Sinch, ensuring seamless transitions into regular marketing broadcasts.

What happens in ZAP POST when a contact unsubscribes in Sinch?
