Web3 API GetNFTs latest info

Technical Issue Reporting
#1

Hi all,

I’m using moralis web3 API to get the NFT of a user for a specific collection. I’m really loving working with moralis but there’s just one issue I’m currently facing. I have a collection on rinkeby and I’m having trouble getting the latest information on that collection. For example I have once account that minted 18 NFTs but the web3 api only returns 15. I have another account that minted 3 but moralis returns 0.

Is there a way to make moralis update to the latest info or watch the nft contract? Also, could this just be a testnet issue or is there something I have to always do to ensure moralis fetches the latest information. Thanks!

  • Edit. The three of the second account have been found now, but still having issues finding the 3 missin from the first account. So the question is basically: is there any way I can improve the web3 api for my particular collection?

Can you give examples for those cases where it doesn’t work now?

Moralis code:

const usersNFTs = await Web3Api.account.getNFTs(options);
            if (usersNFTs) {
                /*console.log(usersNFTs.result.sort((a,b) => {
                    let _ba = parseInt(a.block_number)
                    let _bb = parseInt(b.block_number);

                    if (_ba > _bb)
                        return 1
                    else if (_ba < _bb)
                        return -1
                    else
                        return 0
                }))*/
                //console.log(usersNFTs)
                
                let usersAbstractions = usersNFTs.result.filter(r => r.token_address.toLowerCase() === contract.address.toLowerCase())
                //console.log(usersAbstractions)
                console.log(`Your balance: ${_balance} | NFTs found: ${usersAbstractions.length}`)

Can you paste that address?

Contract: 0x76C6A80d876c892791C552810EBcd2B9ec8C2781
My wallet: 0x9Cc3d5291D1dc1C2E3c49f002CC31eeDBB687c0f
Network: Rinkeby

After first 3-5 mints it works fine but the first 3-5 mints of the collection seem to have this problem

#8

You say that it works fine now, but it took 3-4 minutes until the info was available in web3api?

#9

No I’m saying that for this wallet it’s only found 15/18 NFTs. For all subsequent mints / accounts it’s working fine but for this account it’s not retrieving 3 out of 18.

Anyway, is there any way to make moralis update this data or something like that from my side?
Appreciate the help btw!

=>

{total: 26, page: 0, page_size: 500, result: Array(26), status: 'SYNCED'}

what I’m doing wrong?

#11

Thanks for the answer! I was using the getNFTs instead of getNFTsForContract method. This has solved the issue. Thank you very much for the help.

Final question. Is there anything more I can do to ensure the latest data for my contract is synced? Or does moralis take care of that automatically

#12

Moralis should take care of that automatically, but when you see problem you can post here in forum

#13

Alright! Any resource I can read to understand how you guys are syncing so much contract data? Really curious about that

#14

Moralis is doing that processing on scale and saving the processed data in an intermediate database
