4. Debugging your metadata

Using the /validate endpoint

If you're having issues getting your items to show up properly on OpenSea (perhaps they're missing an image or attributes), you can debug your metadata using the following API endpoint.

https://testnets-api.opensea.io/asset/<your_contract_address>/<your_token_id>/validate/ 

or

https://api.opensea.io/asset/<your_contract_address>/<your_token_id>/validate/ 

Simply hit this URL with your contract address and token ID to see if there are any errors with your metadata URL. If you need additional help, feel free to reach out to us on our Discord channel.
