We at ONE store provide Android Software development kits (SDK) and resources (API) which Android developers can use.\
We continue our efforts to expand the scope of support for the developers.

### **ONE store 3rd party payment guide** <a href="#tools-onestore3rdpartypaymentguide" id="tools-onestore3rdpartypaymentguide"></a>

In addition to ONE store IAP, ONE store support 3rd party payment method too.\
The 3rd party payment is an enabler for payment service provided by the seller through 3rd party Payment Gateway (PG),\
such as PayPal, without ONE store’s in-app payment module (in-app SDK).
