@execc excellent :) I see the contract has received the callback correctly here @ https://etherscan.io/tx/0x4d5745c2790d044c1378f5fcc7400d7815b90dac3668e6ed29284af55bc73293
do you have any specific question re that query?
@oraclize-support Any clues about my issue? I've tried it again, same result, query id: f2f2fb69ba2a8af545151c76ff0e51e8962a17bca7bb0edf843f5488f2c92a66
txn hash:
0xf569dab90f01908e0facd57b8e0e81085505ec4831dcaab8d249d61d142b8d72
It says that a transaction from your address to my contract failed with an out of gas error :/

@oraclize-support Hello, How would I do a post request inside the callback function after I've got a result? Here is an example.
function callback(bytes32 myid, string result) public {
if (msg.sender != provable_cbAddress()) revert();
statusFromDatabase = result;
provable_query("URL",
"http://mywebsite/api/pending-orders",
'{"address":"0x5b38da6a701c568545dcfcb03fcb875f56beddc4", "status":"1"}'
);
}Everything I try seems to not work. Thanks in advance
@oraclize-support i have set up oraclize on my ethereum based private network with the help of ethereum bridge module.
Now in docs it is mentioned that some account will be deducted from my contract to pay for the fees.
The fee consist of two parts, as mentioned in the docs-
a) The amount of Wei which corresponds, using a recent exchange rate, to the USD price for the data source and the authenticity proof requested
b) The amount of Wei which Provable will spend in gas for sending the callback transaction
But on my private network , amount is being deducted from my contract and also my account is being used to send the callback transaction.
i run the bridge with this command
node bridge.js -H https://myRpcUrl -a 7 --oar 0x519039A70733C152344d4517020C2362c580Ef20and this account 7 is actually paying the callback transaction fees, gasLimit 200000, gasPrice 20GWei
Am i paying extra or is this how it works on ethereum based private networks ?
@oraclize-support i don't think the same happens on ethereum mainnet or testnets, on private network i have funded the above mentioned account from which the callback transactions are being made.
I don't think on ethereum networks people fund accounts for the callback transactions.
callback address(es) are controlled by the Provable service. So on those networks you won't see their balances changes unless you're specifically looking to.

@phyermax - what network are you on?
@kallolborah - we are not integrated on Quorom at the moment but we integrate wherever there is demand and so we will log your demand.
@habdelra - thank you for your info and your helping that other user - much appreciated!
@poa010101 - the oracle is not integrated on Binance yet either but we'll note your demand.
I still can't seem to get this working. Trying to make a post request inside a callback function programmatically (without clicking a button to trigger it). It's working fine if I put it as a public function and click it, but still, nothing gets sent to my DB if I want to do it straight after the callback function has been called.
What I'm trying to do is a get request and when the callback is fired then do the post request
Thanks again
