Integration Documentation

Step 1: Generate a Report

Connect the refurbished controller and run the Full Diagnostic test. Once completed, a health score and report are generated for the hardware evidence.

Step 2: Copy the Share Link

Use the Copy Share Link button on your report. The entire report is encoded into the link itself (with a checksum), so it opens for any buyer on any device with no login.

Share links look like this:

https://controllertesting.com/verify?d=eyJ2Ijo...&c=8f3a1c0d

Step 3: Embed in Your Listing

Paste the share link into your listing description, or embed it as an iframe:

<iframe 
  src="https://controllertesting.com/verify?d=YOUR_PAYLOAD&c=YOUR_CHECKSUM&embed=1" 
  width="100%" 
  height="600" 
  frameborder="0" 
  title="Controller Diagnostic Report">
</iframe>

The embed=1 parameter strips the site navigation so only the certificate card renders inside the frame.

Frequently Asked Questions

How do I embed a diagnostic report on my eBay listing? +

Generate a report using our Full Diagnostic tool, copy the provided self-verifying share link, and embed it on your listing. The report travels inside the link itself, so any buyer — on any device, in any browser — can open it without an account.

Is the Controller Diagnostic API free for sellers? +

Yes, our diagnostic tools and the report embedding functionality are currently free for both casual users and high-volume refurbishers.

Do buyers need to create an account to view the report? +

No. Reports travel inside the share link itself (a self-verifying payload with a checksum), so they open for any viewer with no login, no server lookup, and no stored database entry.
