      Code Block
      language typescript
      ProofSpace.WebLinker.start(elem, { serviceDid: <YOUR_SERVICE_DID>, interactionId: <YOUR_OAUTH_ACTION_ID>, instanceId: <YOUR_OAUTH_INSTANCE_ID>, size: 300 // size of QR code in pixels }).then(() => { console.log(‘QR Initialized’); });

   2. For the interaction with SSI OAuth flow

      Code Block
      language typescript
      ProofSpace.WebLinker.startWithSSIOAuth(elem, { clientId: <OAUHT_EXTENSION_ID> serviceDid: <YOUR_SERVICE_DID>, interactionId: <YOUR_OAUTH_ACTION_ID>, instanceId: <YOUR_OAUTH_INSTANCE_ID>, size: 300 // size of QR code in pixels }).then((result) => { console.log(result.access_token); });

To find the “clientId”, install the “SSI OAuth Extension” to your service, then add it to the desired interaction. Click on the installed “SSI OAuth Extension” in the interaction. The first line will be “clientId.”
