Answer 1

Since code generator is also become part of consumer queue after 2.3.x , you can manually run this command to start generating the coupon codes,

php bin/magento queue:consumers:start codegeneratorProcessor

thanks.

Answer 2

Because this is a bug on Magento 2.1. There is a difference about the type of coupon which auto-generate To fix it. Go to file vendor/magento/module-sales-rule/Model/ResourceModel/Rule/Collection.php

 
$orWhereConditions = [
    $connection->quoteInto(
        '(main_table.coupon_type = ? AND rule_coupons.type = 0)',
        \Magento\SalesRule\Model\Rule::COUPON_TYPE_AUTO
    ),
    ....
];

Then change rule_coupons.type = 0 to rule_coupons.type = 1 Hope that this will help everyone

1. I just given "from date" only for the price rule.
2. In the cart price rules form page, we can see that either Stop Rules Processing or Discard Subsequent Rules.

• Just set "Yes" for Stop Rules Processing/Discard Subsequent Rules.
• Some existing coupon may affect your current coupon.I removed that coupon.

4. Make sure in the manage coupon codes tab, confirm either coupon is used or unused.

I've created the auto generated coupon using the below api.

$accessToken = 'ymuo1rkbggrh467tmtlk502hw9fd2v8z'
$response = Http::withHeaders([
            'Content-Type' => 'application/json',
            'Authorization' => 'Bearer ' . $accessToken,
        ])->post(
            'https://example.com/rest/default/V1/salesRules',
            [
                'rule' => [
                    "name" => "TESTCOUPON",
                    "website_ids" => [1],
                    "customer_group_ids" => [0, 1, 2, 3],
                    "uses_per_customer" => 1,
                    "is_active" => true,
                    "stop_rules_processing" => true,
                    "is_advanced" => true,
                    "sort_order" => 0,
                    "discount_amount" => 10,
                    "discount_step" => 0,
                    "apply_to_shipping" => false,
                    "times_used" => 0,
                    "is_rss" => true,
                    "coupon_type" => "SPECIFIC_COUPON",
                    "use_auto_generation" => true, // Setting auto-generation to false
                    "uses_per_coupon" => 1,
                    "from_date" => Carbon::now()->toDateString(),
                    "simple_action" => "by_fixed"
                ]
            ]
        );
        $actionRule = $response->json();

        // Make POST request to create autogenerate coupon by using rule_id
        $response = Http::withHeaders([
            'Authorization' => 'Bearer ' . $accessToken,
            'Content-Type' => 'application/json',
        ])->post('https://example.com/rest/default/V1/coupons/generate', [
            'couponSpec' => [
                'rule_id' => $actionRule['rule_id'],
                'quantity' => 5,
                'length' => 12,
            ]
        ]);

Finally, The coupon is working.Here, I attached the screenshot for your reference.
