I created the coupon in function its works perfectly now I want to apply sales rules (apply on specific product) my code is

 public function setCoupon()

 // $this->_state->setAreaCode('adminhtml'); 
 // $this->_state->setAreaCode('frontend'); 


 // $coupon['name'] = 'Offer_asad17';
 $coupon['name'] = 'Sheikh';
 $coupon['desc'] = 'Discount for vip signup coupon.';
 $coupon['start'] = date('Y-m-d');
 $coupon['end'] = '';
 $coupon['max_redemptions'] = 1;
 $coupon['discount_type'] ='by_fixed';
 $coupon['discount_amount'] = 15;
 $coupon['flag_is_free_shipping'] = 'no';
 $coupon['redemptions'] = 1;
 // $coupon['code'] ='NL017-1234'; //this code will normally be autogenerated but i am hard coding for testing purposes 
 $coupon['code'] ='Sheikh-1234'; //this code will normally be autogenerated but i am hard coding for testing purposes 

 $this->_rule->setName($coupon['name'])
 ->setDescription($coupon['desc'])
 ->setFromDate($coupon['start'])
 ->setToDate($coupon['end'])
 ->setUsesPerCustomer($coupon['max_redemptions'])
 ->setCustomerGroupIds(array('0','1','2','3',))
 ->setIsActive(1)
 ->setSimpleAction($coupon['discount_type'])
 ->setDiscountAmount($coupon['discount_amount'])
 ->setDiscountQty(1)
 ->setApplyToShipping($coupon['flag_is_free_shipping'])
 ->setTimesUsed($coupon['redemptions'])
 ->setWebsiteIds(array('1'))
 ->setCouponType(2)
 // ->setProductIds(array('1','2','3'))
 // ->setProductIds([1,2,3])
 // ->setProductIds(array(1,2,3))
 //->setProductIds([1,2,3])
 // ->setProductIds('1')
 ->setProductIds(1)
 ->setCouponCode($coupon['code'])
 ->setUsesPerCoupon(NULL);
 $this->_rule->save();

try this my friend, this code to add rules before create coupon

use MagentoSalesRuleModelRuleFactory;

protected $_ruleFactory;

public function __construct(
 Context $context,
 RuleFactory $ruleFactory
 )
 
 $this->_ruleRepostitory = $ruleRepostitory;
 parent::__construct($context);
 


public function execute()
 
$ruleModel = $this->_ruleFactory->create();
$ruleModel->setName($getRule->getName())
 ->setDescription($getRule->getDescription())
 ->setCouponCode($getCoupon['code'])
 ->setFromDate($getRule->getFromDate())
 ->setToDate($getRule->getFromDate())
 ->setUsesPerCustomer($getRule->getUsesPerCustomer())
 ->setCustomerGroupIds($getRule->getCustomerGroupIds())
 ->setIsActive($getRule->getIsActive())
 ->setStopRulesProcessing($getRule->getStopRulesProcessing())
 ->setIsAdvanced($getRule->getIsAdvanced())
 ->setProductIds($getRule->getProductIds())
 ->setSortOrder($getRule->getSortOrder())
 ->setSimpleAction($getRule->getSimpleAction())
 ->setDiscountAmount($getRule->getDiscountAmount())
 ->setDiscountQty($getRule->getDiscountQty())
 ->setDiscountStep($getRule->getDiscountStep())
 ->setSimpleFreeShipping($getRule->getSimpleFreeShipping())
 ->setApplyToShipping($getRule->getApplyToShipping())
 ->setTimesUsed($getRule->getTimesUsed())
 ->setIsRss($getRule->getIsRss())
 ->setWebsiteIds($getRule->getWebsiteIds())
 ->setCouponType(2)
 ->setUsesPerCoupon($getRule->getUsesPerCoupon());
 $ruleModel->save();

Remember, change " $getRule->... " = your data, good luck
