Introduction

The NFT Collection Activity webhook allows you to track all the IDs in ERC721 and ERC1155 token contracts. This provides your app with real-time state changes when an NFT is transferred between addresses.

Example Response

When an ERC721 or ERC1155 from the NFT contracts that you are tracking gets transferred, you receive a response from the webhook that looks like this:
