FAQ

Questions about Slack + Square.

How long does it take to connect Slack and Square on TinyCommand?

Under two minutes. Authorize Slack and Square once each, drop the Slack trigger and Square action onto a workflow canvas, map a couple of fields, and publish. No code, no glue.

Is the Slack ↔ Square integration real-time?

Yes. Both Slack and Square expose webhooks, so events from one fire workflows in the other within seconds rather than on a polling interval.

Can I filter or transform data between Slack and Square?

Yes. Add a Filter node to only pass through matching events, a Switch node to branch by value, or an AI / Code node to transform payloads before they hit Square.

What Slack events can trigger a Square workflow?

Any of the 13 Slack triggers, including "App Home Opened". Each fires in real time when the matching event happens in Slack.

Do I need a paid plan to use Slack with Square?

No. Both integrations come on every plan, including Free, which includes 1,000 credits a month with no credit card. Each workflow step uses 1 credit, and paid plans include more credits and team seats when you need them.

What if I want Square → Slack instead?

Build it the same way, in reverse. There's a dedicated /integrations/square/with/slack page with the reverse-direction triggers and actions.
