KYB Deep Link

The KYB deep link takes a business user straight into KYB (Know Your Business) verification from a single widget URL — no quote required. Use it when you want a partner's users to complete business verification ahead of, or independently from, any ramp.

It is a variant of the hosted widget: instead of POST /v1/session/create, you link the user directly to the widget with a KYB query parameter.

Flow

?kyb / ?kybLocked  →  email + OTP sign-in  →  region selector  →  provider KYB  →  "KYB Completed" screen

Brazil routes to the local payment partner's KYB flow. The user enters the company name and CNPJ together on the company form, then completes the partner's hosted company and representative verification.

Mexico / Colombia / USA route to the local payment partner's business KYB form (the business customer type is preselected).

Europe is intentionally excluded — it is individual KYC only and requires a connected wallet, so it cannot complete a quote-less KYB deep link.

After verification the user lands on a KYB Completed screen. Continue returns them to the standard quote form with the session still authenticated and the deep-link parameters stripped from the URL.

URL Parameters

Append one of these to the widget URL (e.g. https://www.vortexfinance.co/widget?kyb):

URL	Behavior
`?kyb`	KYB mode; the region selector is shown.
`?kyb=BR` \| `MX` \| `CO` \| `US`	Selector shown with the region preselected. The user can still change it.
`?kybLocked=BR` \| `MX` \| `CO` \| `US`	Selector skipped, region pinned, back navigation into the selector disabled.
`?kybLocked=BR` (specifically)	Additionally defaults the widget locale to `pt-BR`. An explicit locale in the path still wins (e.g. `/en/widget?kybLocked=BR` stays English).
unknown or empty region code (e.g. `?kybLocked=ZZ`, `?kybLocked`)	Degrades gracefully to the open selector; the region is not treated as locked.

Query keys are case-sensitive: use kyb and kybLocked exactly. Region codes are case-insensitive.

Attribution

externalSessionId, partnerId, and apiKey are forwarded in KYB mode exactly as in the quoted widget flow, so partner and session attribution work the same way:

https://www.vortexfinance.co/widget?kybLocked=BR&externalSessionId=my-session-id&partnerId=my-partner&apiKey=pk_live_...

Pass your partner public key (pk_live_* / pk_test_*) as apiKey for attribution. externalSessionId is your own opaque identifier and is echoed back in webhook payloads.

Embedding

The KYB deep link is a normal widget URL, so the same embed options apply:

Underlying KYB Onboarding

For Brazil, the deep link drives POST /v1/brla/createSubaccount without a quoteId — the subaccount is created from the company name and CNPJ collected on the form, and the optional quote association is simply omitted. See Fiat Corridors for how BRL onboarding relates to the ramp flow.
