I am having a problem with http Request

My code works perfectly with printing but what i am looking for is to return the value returned from the php code to another function which i couldnt approach

here is my code

FString AHttpActor::MyHttpCall(FString Url)
{
	TSharedRef<IHttpRequest> Request = Http->CreateRequest();
	Request->OnProcessRequestComplete().BindUObject(this, &AHttpActor::OnResponseReceived);
	Request->SetURL(Url);
	Request->SetVerb("GET");
	Request->SetHeader(TEXT("User-Agent"), "X-UnrealEngine-Agent");
	Request->SetHeader("Content-Type", TEXT("application/json"));
	Request->ProcessRequest();
	GEngine->AddOnScreenDebugMessage(1, 2.0f, FColor::Green, value);//prints nothing
	return value;
}


/*Response*/
void AHttpActor::OnResponseReceived(FHttpRequestPtr Request, FHttpResponsePtr Response, bool bWasSuccessful)
{

	TSharedPtr<FJsonObject> JsonObject;

	TSharedRef<TJsonReader<>> Reader = TJsonReaderFactory<>::Create(Response->GetContentAsString());
	if (FJsonSerializer::Deserialize(Reader, JsonObject))
	{
		FString recieved = JsonObject->GetStringField("Brain");
		GEngine->AddOnScreenDebugMessage(1, 2.0f, FColor::Green, value);//prints the value
		value = recieved;
	}
}
