I’m trying to get data from an off-chain API to use it in my smart contract. For this, I’m using Chainlink oracle.

I can get data from api like this:
[{“id”:1,”name”:”John Smith”,”email”:”[email protected]”,”values”:[8.03,0.8,1.49,5.71,3.44,7.1,5.74],”quantities”:[1,2,20,11,19,10,20]},
{“id”:2,”name”:”Emily Johnson”,”email”:”[email protected]”,”values”:[1.11,3.62,9.15,6.15,1.5,2.91,9.3],”quantities”:[13,20,17,14,20,10,3]},
{“id”:3,”name”:”Michael Brown”,”email”:”[email protected]”,”values”:[2.71,9.16,8.44,4.25,7.59,8.15,0.26],”quantities”:[11,6,4,19,2,14,20]}]

To get an array from api, I did like that:

    constructor() ConfirmedOwner(msg.sender) {
        _setChainlinkToken(0x779877A7B0D9E8603169DdbD7836e478b4624789);
        _setChainlinkOracle(0x6090149792dAAeE9D1D568c9f9a6F6B46AA29eFD);
        jobId = "53f9755920cd451a8fe46f5087468395";
        fee = (1 * LINK_DIVISIBILITY) / 10; // 0,1 * 10**18 (Varies by network and job)
    }

   function requestFirstId() public returns (bytes32 requestId) {
        Chainlink.Request memory req = _buildChainlinkRequest(
            jobId,
            address(this),
            this.fulfill.selector
        );

        req._add(
            "get",
            url
        );
        req._add("path", "0,values,0");
        req._add("path", "0,values,1");
        int256 timesAmount = 10 ** 18;
        req._addInt("times", timesAmount);

        return _sendChainlinkRequest(req, fee);

    }

    function fulfill(
        bytes32 _requestId,
        uint256 _value0,
        uint256 _value1

    ) public recordChainlinkFulfillment(_requestId) {
        emit RequestFirstId(_requestId, _value0);
        value0 = _value0;
        value1 = _value1;

    }

But it isn’t worked.

And I want to get values and quantities from this api

How can I get the values and quantities using Chainlink Oracle?
