First, ask your MLS provider for your RESO credentials. If they need a IP address to white-list, please provide 52.20.120.32.
You will receive the following credentials:
RESO URL
Server Token
Dataset ID (optional)
With these credentials in hand, click here to add MLS searching to your site.
On Wix, click Add to Site and choose your existing website. After a few moments, the MLS Search App will be in place.
Now, simply click into Settings and go to the RESO tab. Paste in your credentials and you are done!
