any sample code for fulfillBasicOrder?

[ho92930]

Hi there, i'm trying to buy an NFT through fulfillBasicOrder, but I'm having trouble figuring out 1) what fulfillment data we need, 2) how to get that fulfillment data from OpenSea.

1. Is there any sample code for how to use fulfillBasic Order?

Does this look like it would work?

Order details

route = 'ETH_TO_ERC721' # Basic route to fulfill ERC721 order
order = {
'offer': {
'token': 'ERC721', # Offer item is ERC721
'tokenId': 'YOUR_TOKEN_ID', # ERC721 token ID you want to buy
'amount': 1 # Amount of ERC721 token to buy
},
'buy': {
'type': 'ETH', # Consideration item is Ether
'amount': 'YOUR_CONSIDERATION_AMOUNT' # Amount of Ether to pay for the NFT
},
'seller': '0xSELLER_ADDRESS' # Seller's wallet address
}

2. For this page https://docs.opensea.io/reference/fulfill-a-listing

listing ____
listing to fulfill

fulfiller ____
fulfilling wallet address

But when I try to use the sample payload on the page
"{
"listing": {
"hash": "0x6ba3577b78869b26210550176d7376577a1e2b10d76add5a8d022df9dc2f6429",
"chain": "ethereum",
"protocol_address": "0x00000000000001ad428e4906aE43D8F9852d0dD6"
},
"fulfiller": {
"address": "0xD77F375A33b1109e82f3C46A30537F1E019708eB"
}
}"

the payload gets all mucked up
"payload = {
"listing": ""listing": {
"hash": "0x6ba3577b78869b26210550176d7376577a1e2b10d76add5a8d022df9dc2f6429",
"chain": "ethereum",
"protocol_address": "0x00000000000001ad428e4906aE43D8F9852d0dD6"
",
"fulfiller": " "fulfiller": {
"address": "0xD77F375A33b1109e82f3C46A30537F1E019708eB"
"
}
he"

And the response is
"{
"errors": [
{
"listing": [
"value is not a valid dict"
],
"fulfiller": [
"value is not a valid dict"
]
}
]
}"

Thank you!
