If you use Wix-managed pages for processes such as checkout, Wix returns the visitor to your site or app after the process is completed. To protect data security, Wix only ever redirects visitors to addresses you approve.
For non-authorization related redirects, you provide a domain to allow redirects to all URLs under that domain.
Authorization related redirects require exact matching URIs. To set allowed authorization redirect URIs, see Allowed Authorization Redirect URIs.
To add Allowed redirect domains for non-authorization redirects:
Open your project dashboard and click Settings in the left sidebar menu.
Scroll down to the Advanced section and click Headless Settings.
Go to your OAuth app's settings.
Scroll down to the URLs section and go to the Allowed redirect domains section.
Click Add Redirect Domain and enter a domain you authorize Wix to redirect back to from Wix-managed pages. For example,
www.my-site.comauthorizes all URLs under this domain. To authorize multiple domains, click Add Redirect Domain again as many times as you need.
