# Integrate client
Integrate iframe in order to ensure customer interaction with protocol on operator's site. An example of the integration is available on a [demo site](https://casino.rewindprotocol.com/).
Default link for iframe:
```
https://casino.demo.rewindprotocol.com/dashboard?sid=&isMobile=false&lang=en&helpLink=https://www.facebook.com/
```

-H 'X-Rewind-Api: AaaAaaAaaAaaAaa' \
-H 'X-Rewind-Signature: ab678e428a215c2de3b584245ed9326562add02e5a4031391df5b492d61fb3bb4b03f33029e0205f159305cce205cb4ae566551caa90cc34a318657b7bf19ea5' \
