Payment

The user is provided with wallet details to which payment must be made.
The user makes a payment in their wallet app and receives a unique transaction number.
Next, the user enters a unique transaction number in the payment window, after which the transaction is activated.
Paykassma sends a postback to the merchant's side.
Funds are credited to the user’s balance on the merchant platform.

Payment window integration (plugin)

Example of a link to open a Bank Transfer Manual payment window:

`https://plugin.{URL_сервера}/? label=label &currency_code=LKR &lang=lang &wallet_type=banktransfer_manual &custom_transaction_id=custom_transaction_id &fixed_amount=fixed_amount &payment_url_success_id=2 &payment_url_pending_id=3 &payment_url_fail_id=1 &success_url=hash &fail_url=hash &pending_url=hash`

Code Block
wallet_type=banktransfer_manual currency_code=LKR Available languages (lang): en, si

Info

Pay attention to the description of the parameters payment_url_success_id / payment_url_fail_id/ payment_url_pending_id and success_url / fail_url / pending_url.
To use payment_url_success_id / payment_url_fail_id / payment_url_pending_id you need to send the URLs to Paykassma support and use the received IDs in the parameters.
To use success_url / fail_url / pending_url you must use hashing URLs ( For more details on hashing click here ).
