The popularity of an NFT is largely driven by the imagery and media content it displays in NFT marketplaces and wallet applications.

As a user of the Ticket Engine you are in control over the image and multimedia content of your NFT tickets and we provide the updateTicket action to allow you to update the URI reference which points to your image asset. At present, hosting of the image assets at this URI would remain the responsibility of the integrator.

Accepted Formats

We support all image and video filetypes commonly used as NFT content and the API will not restrict updates based on filetype:

  • JPG
  • PNG
  • GIF
  • MP4
  • WEBM

Note however that support for display will depend on browser compatibility and content should be checked prior to updating. This is important as most NFT collectors will be using a web browser to explore marketplace collections.

Although we do not set a limit on the filesize as this is hosted within your own storage, be aware that NFT marketplaces may place size restictions on multimedia content due to how they ingest and cache this data. For that reason we do not recommend exceeding 100MB in file size.

On-chain Referencing

The Metadata endpoint is compatible with the OpenSea Metadata Standards. Each NFT has its own unique public JSON metadata endpoint and this can be seen by calling the tokenURI(uint256 _tokenId) for the contract address for each event.
