Magento2 programmatically create coupon

In this article, i have explaining how to we can create coupon programmatically.

At Magento 2, if you wish to create a coupon problematically .

1.Create Cart Price rules

For a create rules, i have used repository interface classes:

Magento\SalesRule\Api\RuleRepositoryInterface
Magento\SalesRule\Api\CouponRepositoryInterface

For set the data for rules repository class, we have use the interface

Magento\SalesRule\Api\Data\RuleInterface

This interface some setter methods using this setter method, using those method you can set discount percent/amount ,rules starting & ending date ,conditions of a rules.

Here an example code of Create Cart price rule

<?php

namespace DevAmitbera\CustomModule\Model;

use Magento\SalesRule\Api\Data\RuleInterface;
use Magento\SalesRule\Api\RuleRepositoryInterface;
use Magento\SalesRule\Model\CouponFactory;
use Magento\SalesRule\Model\RuleFactory;


class Test 
{

    /**
     * @var RuleInterface
     */
    private $rule;

    /**
     * @var RuleFactory
     */
    private $ruleFactory;

    /**
     * @var RuleRepositoryInterface
     */
    private $RuleRepository;

    public function __construct(
            RuleRepositoryInterface $RuleRepository,
            RuleFactory $ruleFactory,
            RuleInterface $rule
    ) {
        $this->RuleRepository = $RuleRepository;
        $this->ruleFactory = $ruleFactory;
        $this->rule = $rule;
    }


    public function createCartRules() {

        $rule =$this->rule;
        $rule->setName('5% discount') // Rules name
                ->setDescription('5% discount on all')
                ->setIsAdvanced(true)
                ->setStopRulesProcessing(false)
                ->setDiscountQty(5)
                ->setCustomerGroupIds([0, 1])
                ->setWebsiteIds([1])
                ->setUseAutoGeneration(0)    // If want to auto generate
                ->setCouponType(RuleInterface::COUPON_TYPE_SPECIFIC_COUPON)
                ->setSimpleAction(RuleInterface::DISCOUNT_ACTION_FIXED_AMOUNT_FOR_CART)
                ->setUsesPerCoupon(100)
                ->setUsesPerCustomer(2)
                ->setDiscountAmount(10)
                ->setFromDate('2019-04-01') //Format YYYY-MM-DD
                ->setToDate('2039-04-14') //Format YYYY-MM-DD
                ->setIsActive(true);

        try {
            $resultRules = $this->RuleRepository->save($rule);
        } catch (\Magento\Framework\Exception\LocalizedException $ex) {
            var_dump($ex->getMessage());
        }
    }

}

Create Coupon of the rule

After creating Cart Price rules, you may be want to the coupon code

Use below Class

Magento\SalesRule\Api\CouponRepositoryInterface:save

Data Provider interface : Magento\SalesRule\Api\Data\CouponInterface

/*

* @coupon \Magento\SalesRule\Api\Data\CouponInterface
*/
$coupon = $this->couponFactory->create();

$coupon->setCode($couponCode)
        ->setIsPrimary(true)
        ->setRuleId($rulesId());
$this->couponRepository->save($coupon);

Here note that setIsPrimary() parameters should be true /false means boolean

If you want to Coupon Code at Rule Information  Section

Code Sample for Create Single Coupon for a rule

<?php


namespace Stackexchange\Magento\Observer;

use Magento\SalesRule\Api\CouponRepositoryInterface;
use Magento\SalesRule\Api\Data\CouponInterface;
use Magento\SalesRule\Api\Data\RuleInterface;
use Magento\SalesRule\Api\RuleRepositoryInterface;
use Magento\SalesRule\Model\CouponFactory;
use Magento\SalesRule\Model\RuleFactory;
use Magento\Framework\Math\Random;
use Magento\SalesRule\Api\Data\CouponGenerationSpecInterfaceFactory;
use Magento\SalesRule\Model\Service\CouponManagementService;

class CreateCouponCustomer {

    /**
     * @var CouponGenerationSpecInterfaceFactory
     */
    private $generationSpecFactory;

    /**
     * @var CouponManagementService
     */
    private $couponManagementService;

    /**
     * @var Random
     */
    private $random;

    /**
     * @var CouponFactory
     */
    private $couponFactory;

    /**
     * @var RuleFactory
     */
    private $ruleFactory;

    /**
     * @var CouponRepositoryInterface
     */
    private $couponRepository;

    /**
     * @var RuleRepositoryInterface
     */
    private $RuleRepository;

    public function __construct(
      CouponRepositoryInterface $couponRepository,
      RuleRepositoryInterface $RuleRepository,
      CouponFactory $couponFactory,   
      RuleFactory $ruleFactory,
      Random $random,
     CouponGenerationSpecInterfaceFactory $generationSpecFactory,
     CouponManagementService $couponManagementService       
    ) {
        
        $this->RuleRepository = $RuleRepository;
        $this->couponRepository = $couponRepository;
        $this->ruleFactory = $ruleFactory;
        $this->couponFactory = $couponFactory;
        $this->random = $random;
        $this->couponManagementService = $couponManagementService;
        $this->generationSpecFactory = $generationSpecFactory;
    }
    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $customer = $observer->getEvent()->getCustomer();
        $rule =  $this->ruleFactory->create();
        $rule->setName('5% discount')
            ->setIsAdvanced(true)
            ->setStopRulesProcessing(false)
            ->setDiscountQty(10)
            ->setCustomerGroupIds([$customer->getGroupId()])
            ->setWebsiteIds([1])
            ->setCouponType(RuleInterface::COUPON_TYPE_SPECIFIC_COUPON)
            ->setSimpleAction(RuleInterface::DISCOUNT_ACTION_FIXED_AMOUNT_FOR_CART)
            ->setDiscountAmount(10)
            ->setIsActive(true);
        
        try{
            $resultRules = $this->RuleRepository->save($rule);
            $this->createCouponCode($resultRules);
        } catch (\Magento\Framework\Exception\LocalizedException $ex) {

        }
        
    }
    private function createCouponCode(RuleInterface $rule)
    {
        $couponCode = $this->random->getRandomString(8);
        $coupon = $this->couponFactory->create();
        $coupon->setCode($couponCode)
                ->setIsPrimary(1)
                ->setRuleId($rule->getRuleId());
        $this->couponRepository->save($coupon);
    }
}
 At the example, I have created a random coupon code by creating 8 lengths using Magento\Framework\Math\Random::getRandomString(8)

Create Auto generate multiple Coupon for a single rule

Want auto generate multiple Coupon codes, that you donot need to use below class

Magento\SalesRule\Api\CouponRepositoryInterface;
Magento\SalesRule\Api\Data\CouponInterface;

Used the classes:

  • Magento\SalesRule\Api\Data\CouponGenerationSpecInterfaceFactory;
  • Magento\SalesRule\Model\Service\CouponManagementService;

This is coupon does not show at Rule Information  

Auto generate Coupon

Section and it will show at Manage Coupon Codes section.

        $couponSpecData = [
            'rule_id' => $ruleId(),
            'qty' => 5, // How many coupon you want to create 
            'length' => 12, // Coupon length
            'format' => 'alphanum', // Alphanumeric = alphanum, Alphabetical = alpha ,
            'prefix' => 'A', // Can use Null 'prefix' =>  null,
            'suffix' => 'Z', // Can use Null 'prefix' =>  null,
            'dash' => 0, // Can use Null 'prefix' =>  null,
            'quantity' => 5 // How coupon you want to create 
        ];
        /**
         * @var $this->generationSpecFactory \Magento\SalesRule\Api\Data\CouponGenerationSpecInterfaceFactory
         * @var $this->couponManagementService \Magento\SalesRule\Model\Service\CouponManagementService
         */
        $couponSpec = $this->generationSpecFactory->create(['data' => $couponSpecData]);
        $this->couponManagementService->generate($couponSpec);

Here rule_id,Coupon Qty : qty,Code Length:length & quantity,Code Format: format are required fields

Simple Code for Auto generate coupon code

<?php

namespace StackExchange\Magento\Model;

use Magento\SalesRule\Api\CouponRepositoryInterface;
