I'm trying to create a campaign with MAXIMIZE_CONVERSIONS Bid strategy Type.
$budgetService = $adWordsServices->get($session, BudgetService::class);
// Create a budget, which can be shared by multiple campaigns.
$sharedBudget = new Budget();
$sharedBudget->setName($budgetName . uniqid());
$money = new Money();
$money->setMicroAmount($budgetMicroAmount);
$sharedBudget->setAmount($money);
$sharedBudget->setDeliveryMethod($budgetDeliveryMethod);
// Create a budget operation.
$operation = new BudgetOperation();
$operation->setOperand($sharedBudget);
$operation->setOperator(Operator::ADD);
// Create the budget on the server.
$result = $budgetService->mutate([$operation]);
$sharedBudget = $result->getValue()[0];
return $sharedBudget;
