Vendor Admin Panel

The Vendor Admin Panel is where you retrieve API credentials and configure the URLs Spayon uses to communicate with your application.

Accessing the Panel

https://admin.spayon.io

The same panel serves both environments. When Spayon enables Sandbox mode for your account, a banner appears, Sessions and Transactions show sandbox data, and the Settings page shows your Sandbox Client ID and Sandbox Client Secret instead of the live ones. See Sandbox Overview.

Required Configuration

Setting	Description
Callback URL	Endpoint that receives POST payment notifications
Return URL	Page the user is redirected to after payment completes
Cancel URL	Page the user is redirected to when clicking back (optional)
Client ID / Client Secret	Your API credentials — retrieve from the Settings page

URL Requirements

• All URLs must be publicly accessible
• Production: HTTPS required for all URLs
• Sandbox: HTTP and HTTPS both accepted
• Callback URL must handle POST requests; Return and Cancel URLs must handle GET requests

Limitations
