I tried to change token base URL to display the new images of NFTs on opensea.io. But it is not updated immediately.
There is a way to update by specifying force_update=true on Rikeby testnet.
But I don't know how to update it on mainnet. Will it be possible?
Any help will be appreciated.
Try this URL:
https://api.opensea.io/api/v1/asset/<your_contract_address>/<token_id>/?force_update=true
please tell me if this works.
This method may not work on another mainnet example polygon.
Update: There is a manual refresh for metadata on opensea. One can always use that one too.
