Flow checkout and payment of Komoju

This flow is for checkout event

Flow checkout

Checkout by

Redirect user to Komoju page:

Currently we don’t split between credit and convenience store

Prepare payment data before redirect

Payment type : * credit * combini

The info below should be set

EventCheckoutController@postCreateOrder

// Redirect when success
transaction[return_url] =>                           route('showEventCheckoutPaymentReturn', ['event_id'              => $event_id, 'is_payment_successful' => 1]),

//Redirect when error or user cancel payment
transaction[cancel_url] =>                           route('showEventCheckoutPaymentReturn', ['event_id'              => $event_id, 'is_payment_successful' => 1]),

-> for example :

• if payment is ok, the link below will be accessed http://event.vietpro.jp/e/{event_id}/checkout/success?is_payment_successful=1

• if payment is failed the link below will be accessed http://event.vietpro.jp/e/{event_id}/checkout/success?is_payment_cancelled=1

According to Komoju, both of the route above will call this method: EventCheckoutController@showEventCheckoutPaymentReturn

Capture the redirect from Komoju:

Komoju will redirect to the url above with the data below (Remember to verified the http referrer to ensure that the request is from Komoju - or do double checking with Komoju API) As the request will be redirected to checkout/success we only check for the transaction[status]: {status} data

status: captured -> user has paid for the ticket
status: authorized -> user hasn't paid for the ticket
status: cancelled -> user cancelled

Status = captured (User has paid for the ticket)

1. A Ticket will be generated and sent via email to user
2. An order with status 1 (will be created)
3. Total Sales, events vacancies will be updated

Status = canceled (User don’t paid for the ticket)

1. Redirect user to homepage

Status = authorized (User issued a convenience store payment request)

1. An order with status 5 (on hold) will be created
   1. order.status = 5
   2. order.transaction_id = callbackのexternal_order_num (for identified the order when a payment.captured hook is invoked)

Confine payment web hook

Should be configured on Komoju side and call back to VPJ like this

Refer the screenshot below

• Webhook Url will subscribe to these events
  • captured: user completed the payment,
  • expired: the payment is expired , we should clear up the hanging order
  • cancelled: user cancelled when going to the convenience store
• Secret: the secret key should be set to authenticated the request come from Komoju not from hackers. (VPJ’s web hook should validate these secret before any processing)

checkout/webhook

This API is similar with this method EventCheckoutContrller@showEventCheckoutPaymentReturn it should contains these process: * complete the order * update from status 5 -> 1 * send email to user to inform they have completed the payment
