Delete Contact

Delete a contact by mobile number, from one list or from all of your lists at once. Destructive - deletes every matching row, with no undo.

FAQ

Common questions about Square + SMS Fusion

Is there a pre-built Square + SMS Fusion automation?

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

Does this require a pre-built Square or SMS Fusion connector?

No. The Agent works whether or not Square or SMS Fusion 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 can integrating Square with SMS Fusion help recover lost store sales?

By automatically sending personalized text messages through SMS Fusion when shoppers leave items behind in Square, you can remind buyers about their cart and offer timely checkout incentives.

Can inbound text responses in SMS Fusion update customer records in Square?

Yes, when buyers send text messages or call through SMS Fusion, you can send custom requests to log those inquiries directly against their store account in Square.
