Payment / fintech API sandbox
Stripe Sandbox
A Stripe sandbox is an isolated copy of a Stripe account with its own API keys, webhooks and data — now the default way to test, replacing legacy test mode.
Last verified 2026-07-26
Stripe moved from a single legacy "test mode" to Sandboxes: isolated copies of an account, each with independent API keys, webhooks, data and configuration (up to 5 per account). Understanding "test mode vs sandbox vs production" is a common integration question since the model changed.
