How to verify NFT holder eligibility in the campaign

When you create a campaign on a platform like TaskOn, you often need to set the eligibility requirements for the campaign, such as users needing to own a Bored Ape Yacht Club (BAYC) NFT.

Step 1: Get specified NFT owned by address

Here you'll need four parameters: chain, collection_contract_address, wallet_address and nft_token_id.

Once you have obtained all parameters, you can copy the following code:

curl --request GET \
     --url 'https://api.footprint.network/api/v2/nft/balance?chain=Ethereum&collection_contract_address=0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d&wallet_address=0x46efbaedc92067e6d60e84ed6395099723252496&nft_token_id=1' \
     --header 'API-KEY: your-api-key' \
     --header 'accept: application/json'

Step 2: Run the script

In your terminal, you should see the following JSON response:

{
  "message": "success",
  "code": 0,
  "data": {
    "balance": "1",
    "nft_token_id": "1"
  }
}

Step 3: Deploy your validation API

After successfully testing the previous two steps, you can now embed it into your API server and deploy a public API to start using it.
