Opensea clone Abi invalid

Moralis General
#1

Hey Guys
I’m trying to create the MarketItemCreate plug in for my Opensea clone. I keep getting invalid Abi and I’m confused why. I got the Abi from remix.ethereum.org after I deployed my MarketplaceContract. so I’m not sure why it comes back as invalid. I’ve been reading through the forums and people have mentioned its to do with the square brackets at the top and bottom of my Abi but when I delete and try again I get invalid Abi please verify.
Can someone help please as I want to finish this project today/tonight.
Thanks in advance :slight_smile:

You need to be using the portion of the ABI for the event that you want to sync. So it should be:

{
		"anonymous": false,
		"inputs": [
			{
				"indexed": true,
				"internalType": "uint256",
				"name": "itemId",
				"type": "uint256"
			},
			{
				"indexed": true,
				"internalType": "address",
				"name": "nftContract",
				"type": "address"
			},
			{
				"indexed": true,
				"internalType": "uint256",
				"name": "tokenId",
				"type": "uint256"
			},
			{
				"indexed": false,
				"internalType": "address",
				"name": "seller",
				"type": "address"
			},
			{
				"indexed": false,
				"internalType": "address",
				"name": "owner",
				"type": "address"
			},
			{
				"indexed": false,
				"internalType": "uint256",
				"name": "price",
				"type": "uint256"
			},
			{
				"indexed": false,
				"internalType": "bool",
				"name": "sold",
				"type": "bool"
			}
		],
		"name": "MarketItemCreated",
		"type": "event"
}
