# Connection-Less Verification The Connection-less Verification enables the use of ZADA’s W3C standard-compliant credentials for online verification, but instead of being exchanged over an established connection, this service removes the need for an existing connection by using a temporary one, making it easier to implement and use. See demo of how it enables a secure passwordless authentication: [https://www.youtube.com/watch?v=o0pip2Uggjo](https://www.youtube.com/watch?v=o0pip2Uggjo) It works by creating a verification request code snippet as a QR code or Deeplink. The user scans this code with their wallet, selects matching credentials, and approves sharing. The verified data is received on the webhook defined in the QR code. `{"type":"connectionless-verification","metadata": {"policyId": "policyId","tenantId": "your-tenant-Id",},"rcb": "redirect-url", "wcb": "webhook-url",}` This is great for uses such as: * Registration online for new services or mobile apps * Check-in at venues in person * Membership Registrations * Sharing documents online `**Tip:**` `When handling login and long polling, session ID as a query in the webhook could be a good way to identify the user.` ## **Web Implementation (QR Code)** ### **Usage** 1. Create a JSON Object. 2. Convert this object into QR Code. 3. Scan QR Code from ZADA Wallet to perform the verification. ### **Steps** 1. Pass **type** as "connectionless-verification". 2. Pass **metadata** object containing policyId and tenantId. 3. Pass **policyId** as argument. You can get **policyId** from the [policies section](https://github.com/lycheeventures/zada-integration-sample/blob/master/verifications/policies.md) 4. You can get **tenantId** from the tenant that you have created in the tenant section. 5. Pass **rcb** as redirect-url. This will be called by ZADA Wallet after successful verification. You can pass a deeplink to your application to make sure that user returns back to your application from ZADA Wallet. 6. Pass **wcb** as webhook-url. This will be called by ZADA Wallet after successful verification. You can pass a webhook URL to receive verification data. `{` `"type":"connectionless-verification",` `"metadata": {` `"tenantId":"your-tenant-Id",` `"policyId":"policy-Id"` `},` `"rcb": "redirect-url", ` `"wcb":"webhook-url"` `}` Convert the above JSON Object to QR Code. `Using any library or online tool convert the above JSON Object to QR Code.` Scan the QR Code from ZADA Wallet to perform the verification. `Open ZADA wallet and scan this QR code to perform verifications.` ## **Mobile Implementation** ### **Usage** 1. Create a button in your mobile application. 2. Create a JSON Object and convert it to base64. 3. On button click, open ZADA deeplink and pass the base64 object as a query parameter. ### **Steps** 1. Pass **type** as "connectionless-verification". 2. Pass **metadata** object containing policyId and tenantId. 3. Pass **policyId** as argument. You can get **policyId** from the [policies section](https://github.com/lycheeventures/zada-integration-sample/blob/master/verifications/policies.md) 4. You can get **tenantId** from the ZADA Network Admin. 5. Pass **rcb** as redirect-url. This will be called by ZADA Wallet after successful verification. You can pass a deeplink to your application to make sure that user returns back to your application from ZADA Wallet. 6. Pass **wcb** as webhook-url. This will be called by ZADA Wallet after successful verification. You can pass a webhook URL to receive verification data. `let jsonObject = {"type":"connectionless-verification","metadata": { "policyId": "policyId","tenantId": "your-tenant-Id",},"rcb": "redirect-url", "wcb": "webhook-url",}` Convert this object into Base64 and forward it to ZADA deeplink: `zada://network/connectionless-verification?data=${jsonObjectInBase64}` ## Demo of how the deeplink works [https://www.youtube.com/watch?v=3xJ0AOrbgN0](https://www.youtube.com/watch?v=3xJ0AOrbgN0) ## Support If you have any questions, don't hesitate to reach out to us via [help@zada.io](mailto:help@zada.io) or our chat inside the ZADA Portal.
