FAQ

Questions

Does my Stripe data move over?

No, not automatically. Pointing your SDK at Knox changes where new API calls go. Customers, saved cards, subscriptions and their object IDs stay in your Stripe account.

How much do live payments cost?

Can I take live payments today?

Live payments are available by request. Self-serve accounts run in test mode until then.

Which processors does Knox route to?

Knox routes payments to Stripe, Fiserv (3 integrations), NMI, and Paysafe, using your own processor accounts.

Do I have to rewrite my integration?

No. Point the official Stripe SDK at Knox and use your Knox key. The rest of your Stripe integration stays.

How is card data protected?

Card numbers never touch your servers. They're tokenized and held in a secure vault. Read about security.

Set up Knox payments in this repository. Fetch and read https://docs.knoxapi.com/agent-setup/prompt.md, then follow its sandbox integration workflow. Detect whether this is a fresh app, an existing Stripe integration, or another processor; perform the corresponding integration or migration yourself. Keep credentials out of chat and source code, preserve existing payment flows, and verify the integration before reporting success.
