Buying criteria
What makes the cut.
The shortlist is intentionally smaller than the market. A tool belongs here only when its reviewed workflow overlaps the decision on this page.
- 1
Native or bridged?
We distinguish a direct product integration from Zapier, webhooks, CSV handoffs, or a custom API workflow.
- 2
Direction matters
Check what data moves each way, which object owns the truth, and how updates or failures are handled.
- 3
Verify the plan
Integrations are often gated by tier, credits, seats, or admin permissions. Confirm current vendor terms before rollout.
