}

No a nakonec si vytvoříš nějaké krásné šablony na error stránku Paypal/error.latte a success stránku Paypal/success.latte.

That's all.

stripe jsem ještě nedělal Sorry

@Polki dakujem

mame ale este 2 otazky k tomu PayPalu:

1. Ako kontrolujes stav objednavky?

Ja pouzivam /v2/checkout/orders/{order_id} – to funguje dobre pokial je objednavka dokoncena.
Ak dokonecna nie je tak dostanem hlasku ""issue":„INVALID_RESOURCE_ID“,„description“:„Specified resource ID does not exist.“ – ako keby sa ani nikdy nevytvorila. Tym padom mam v systeme bud COMPLETED alebo INVALID_RESOURCE_ID.

Mas to aj ty tak?

2. Ako trigerujes opatovany pokus o zaplatenie?

Priklad: GoPay to ma spravene tak ze pri vytovreni objednavky sa mu zada url ktoru ma zavolat ak sa stav objednavky zmeni. Na danej url sa tym padom viem rozhodnut ci zakaznikovi poslat mail s moznostou opatovneho zaplatenia.
V PayPale ale hladam a nic take nevidim

Dakujem
