Hello and thank you very much for your kind attention. I have a very specific problem and then I let you know the information about what I have and I want to do:
1. My Domain: corners.futbol
2. 3rd-Party Service: Widget of Soccer Standings
3. How do I make the widget request? (Please, see image)
4. Does the service provider have a domain filter? YES, whitelist.
5. What is the problem?: The iframe code works perfectly when my provider of the service add the domain wix.com to the whitelist, then, the widget shows up without problems on my website. When the provider of the widget service add to the whitelist my domain corners.futbol or the iframe domain https://www-corners-futbol.filesusr.com, the request is rejected like ERROR: DOMAIN NOT PERMITTED.
So, the thing is that the widget request does not originate in the corners.futbol domain but in a wix.com domain.
SOLUTION: In some way, can i know from which Wix domain exactly the request originates?
Thanks again for your help and attention.
