Wrapper for Kakaopay REST API. Kakaopay provides convenient way to do internet transaction in Korea because it doesn't need a separate Payment Gateway (PG). The transaction is done only with the user's Kakaotalk account.
Official Kakaopay REST API documentation: here.
Example Implementation: here.
Demo: here.
Via Composer:
composer require se468/kakaopay-php
Used for requesting the user for the transaction. User will receive a message to confirm the transaction.
API Endpoint:
POST /v1/payment/ready HTTP/1.1
Usage Example:
$payment = new \se468\Kakaopay\Payment();
\se468\Kakaopay\Kakaopay::setAdminKey(env('KAKAOPAY_ADMIN_KEY'));
$result = $payment->ready([
'cid' => 'TC0ONETIME',
'partner_order_id' => 'partner_order_id',
'partner_user_id' => 'partner_user_id',
'item_name' => '초코파이',
'quantity' => '1',
'total_amount' => '2200',
'vat_amount' => '200',
'tax_free_amount' => '0',
'approval_url' => 'http://package-development.valet/kakaopay/success',
'cancel_url' => 'http://package-development.valet/kakaopay/fail',
'fail_url' => 'http://package-development.valet/kakaopay/cancel'
]);Here's the explanation of the process:
-
Result from
payment/readywill have transation ID, ortid($result->tid), which you can safely store in your session. -
Store the
tidin session and redirect to$result->next_redirect_pc_url. Customer will be prompted to enter their Kakaopay phone number and password. -
After the customer fills in the form, they will receive a message in their Kakaotalk to approve the transaction. The screen will then redirect to the
approval_urlthat you've provided. -
You can then call
payment/approveusing thetidstored in the session and it will process the payments.
With the given tid from payment ready, approve the transaction to finalize.
POST /v1/payment/approve HTTP/1.1
Example:
$payment = new \se468\Kakaopay\Payment();
\se468\Kakaopay\Kakaopay::setAdminKey(env('KAKAOPAY_ADMIN_KEY'));
$result = $payment->approve([
'cid' => 'TC0ONETIME',
'tid' => 'T1234567890123456789', //tid received from result from 'ready'
'partner_order_id' => 'partner_order_id',
'partner_user_id' => 'partner_user_id',
'pg_token' => $input['pg_token']
]);- You can delete the
tidafter you get the result from here, and store the$resultin your DB, which contains the information about the transaction and show it back to the customer.
Example Payment Ready for subscription
$payment = new \se468\Kakaopay\Payment();
\se468\Kakaopay\Kakaopay::setAdminKey(env('KAKAOPAY_ADMIN_KEY'));
$result = $payment->ready([
'cid' => 'TCSUBSCRIP',
'partner_order_id' => 'partner_order_id',
'partner_user_id' => 'partner_user_id',
'item_name' => '음악정기결제',
'quantity' => '1',
'total_amount' => '9900',
'vat_amount' => '900',
'tax_free_amount' => '0',
'approval_url' => 'http://package-development.valet/kakaopay/subscription/success',
'cancel_url' => 'http://package-development.valet/kakaopay/subscription/fail',
'fail_url' => 'http://package-development.valet/kakaopay/subscription/cancel'

cidparameter.
Check the documentation for single payment. It is exactly same process.
