In addition to their shopping mall business, Akulaku has been enabling E-commerce to sell their merchandise in installment. It allows their customers to pay in installment without a payment card as long as they are registered to Akulaku.

The steps to integrate with Akulaku PayLater Cardless Credit are given below.

Send the charge API request to Midtrans with the selected acquirer.
Redirect the customer to the provider's website.
Redirect your customer back to your page by configuring Finish URL in Midtrans's Dashboard > Settings > Payments.
Handle notifications.

Send a Charge API request with the details of the transaction such as payment_type, transaction_details, item_details, and customer_details. Successful request returns a URL to Akulaku's website.

By default, Akulaku's transaction expiry is 2 hours (min 20s, max 180 days).
