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:

{
  Chainlink.Request memory req = buildChainlinkRequest(_jobId, this, this.fulfill.selector);
  req.add("symbol", _symbol);
  sendChainlinkRequestTo(_oracle, req, oraclePayment);
}

fulfill function

int256 public data;

function fulfill(bytes32 _requestId, int256 _data)
  public
  recordChainlinkFulfillment(_requestId)
{
  data = _data;
