How to test, if my oracle can communicate with plugin and start sharing the data

In your, remix IDE open a new file and name it as PluginClient.sol and copy and paste the code contents.

Override your oracle address & job id in below client contract and deploy it in a remix by overriding the PLI mainnet address like below (Line numbers 21 & 22) in the smart contract to be replaced with your oracle contract address & job-id from the previous steps

        alarmDone = false;
    /* Create a Plugin request to start an alarm and after the time in seconds is up, return throught the fulfillAlarm function */
    function requestAlarmClock(uint256 durationInSeconds) public returns (bytes32 requestId) 
        Plugin.Request memory request = buildPluginRequest(jobId, address(this), this.fulfillAlarm.selector);
        // This will return in 90 seconds
        request.addUint("until", block.timestamp + durationInSeconds);
        return sendPluginRequestTo(oracle, request, fee);
     * Receive the response in the form of uint256
    function fulfillAlarm(bytes32 _requestId, uint256 _volume) public recordPluginFulfillment(_requestId)
        alarmDone = true;
function withdrawPli() public onlyOwner() { 
        PliTokenInterface pliToken = PliTokenInterface(pluginTokenAddress());
        require(pliToken.transfer(msg.sender, pliToken.balanceOf(address(this))), "Unable to transfer");

After deployment, you will receive a contract address- In this case here it is -> xdc3017a414bf657a42fc183143e90d378f05ff0004

Fund your contract address with PLI ( let’s say 1 PLI) before you trigger the sleep task like below

Once you submit the “requestAlarm”, a job will be triggered in your PLUGIN Node like below.

After a couple of seconds, you should see the job is getting completed successfully
