You can do this via Cleeng Capture - a standard feature of Cleeng's Core solution.
Examples of the fields that you can add include:
- date of birth,
- company name,
- mobile phone number,
To gain a deeper understanding of your customers, you can also add your own, custom questions, like what sport they watch the most, etc.
You can mark the fields that you add as optional or mandatory, which is important because a registration process should be easy and intuitive not to discourage your potential customers.
You can turn Capture on and set it up in your broadcaster dashboard under the Admin & Tools tab. For more details on Capture and its setup see the following article: Cleeng Capture.
