ChainLink general API get request Example not working - get

Question

I'm developing a project with using a smartcontract that have to make an API call.
I'm tring to follow the ChainLink guide at this link. I'd like to call the requestRiskData() from another function an than use the output (risk variable updated) to do some stuff. But since it takes like 30 seconds to update the risk value after the oracle call how i can wait to the risk variable to be updated?
Can someone send help?
Thx
I will attach the code here:

"Unable to transfer"
);
}
function myStuff() public payable{
requestRiskData();
if(risk>2){
//DO MY STUFF

}
}
I tried to write the myStuff() function but i don't know how to handle this.

Can you please clarify what you mean by "I'd like to call the requestRiskData() from another function an than use the output (risk variable updated) to do some stuff"
When you say "use the output to do some stuff" do you mean outside the contract (front end) or from inside the smart contract?
If you want to use the value of _risk returned by the oracle, you should just add that logic (or call a helper function that implements that logic) after the value of _risk is set in your fulfill() callback.
so in your case, the following lines should be moved into the end of the fulfill() callback:
if(risk>2){
//DO MY STUFF
}
If you're using the value of _risk from the front end, then use ethersjs or web3js to listen for the RequestRisk event in your front end.
On a side note, you may want to consider renaming that event as its not in the request function but in the callback, so its really should be a RiskReceived or event of that sort of name.
hope this helps!
