Create Your Contract

Import ChainlinkClient.sol into your contract so you can inherit the Chainlink behavior.

pragma solidity ^0.4.24;

import "@chainlink/contracts/v0.4/ChainlinkClient.sol";

contract FinageChainlink is ChainlinkClient {

  uint256 oraclePayment;

  constructor(uint256 _oraclePayment) public {
    setPublicChainlinkToken();
    oraclePayment = _oraclePayment;
  }
  // Additional functions here:

}

pragma solidity ^0.5.0;

import "@chainlink/contracts/v0.5/ChainlinkClient.sol";

contract FinageChainlink is ChainlinkClient {

  uint256 oraclePayment;

  constructor(uint256 _oraclePayment) public {
    setPublicChainlinkToken();
    oraclePayment = _oraclePayment;
  }
  // Additional functions here:

}

pragma solidity ^0.6.0;

import "@chainlink/contracts/v0.6/ChainlinkClient.sol";

contract FinageChainlink is ChainlinkClient {

  uint256 oraclePayment;

  constructor(uint256 _oraclePayment) public {
    setPublicChainlinkToken();
    oraclePayment = _oraclePayment;
  }
  // Additional functions here:
