One integration, one unified API
Tokenize cards, charge any channel with the token, unified webhook callbacks — this page explains the overall integration approach. Full API docs, sandbox, and SDKs are provided at onboarding.
Integration overview (3 steps)
① Tokenize on capture
Embed the secure capture element; the card is tokenized in the user’s browser, plaintext never hits your servers.
② Charge a channel with the token
Your backend charges via neutral forwarding using the token; smart routing/cascade/retry are handled by Flow (coming soon).
③ Webhook callbacks
Token, forward, and 3DS events call back in real time; unified transaction / refund / chargeback callbacks ship with Flow.
