Hosted links

Send a customer to Blink's hosted verification page with nothing but a link. Your backend still creates the session and reads the result; there is no SDK in your product.

The link

hosted linkurl

https://kyc-api.blink-pay.net/h/?t=<sessionToken>&lang=en

Parameter	Required	Description
`t`	yes	The `sessionToken` from the Session API. Exactly one.
`lang`	no	`en` for English. Without it the page is in Arabic.

Flow

Your backend creates a session and builds the link from its sessionToken.
Show the link to the customer — a button in your app or site, an SMS, or a QR code.
The customer completes the document and liveness steps on Blink's page.
Your backend reads the decision with the Result API, using the sessionId you stored.

server.jsjavascript

const { sessionId, sessionToken } = await createBlinkSession(user);   // Session API
await db.kycSessions.insert({ userId: user.id, sessionId });

const link = `https://kyc-api.blink-pay.net/h/?t=${encodeURIComponent(sessionToken)}&lang=en`;
await sms.send(user.phone, `Verify your identity: ${link}`);

Opening a hosted link in your app

Apps built on the Flutter SDK can run a hosted link with native capture instead of the browser. Parsing the link makes no network request:

lib/kyc.dartdart

final outcome = await BlinkKyc.fromHostedLink(scannedLink)
    .present(context)
    .run();

Only accept links whose origin is the Blink API you expect before passing them in.

Treat the link as a secret

The link contains the session token: anyone holding it can run that verification until it expires or is used.
Send it only to the customer it was created for, and create a new one for every attempt.
Don't log full links or send them to analytics.
