Payment window integration (plugin)
Example of a link to open a Ipay Manual payment window:
https://plugin.{URL_сервера}/?label=label¤cy_code=LKR&lang=en&wallet_type=ipay_manual&custom_transaction_id=custom_transaction_id&fixed_amount=fixed_amount&payment_url_fail_id=1 |
|---|
wallet_type=ipay_manual currency_code=PKR Available languages (lang): en, si
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 ).
