Javascript API

Most of methods returns a Promise.

open()

Important: Opens the service channel to RNCustomBilling. Must be called (once!) before any other billing methods can be called.

import RNCustomBilling from 'react-native-custom-billing'

...

RNCustomBilling.open()
.then(() => RNCustomBilling.purchase('YOUR_SKU','DEVELOPER_PAYLOAD',RC_REQUEST))
.catch(err => console.log('Vendor err:', err))

close()

Important: Must be called to close the service channel to RNCustomBilling, when you are done doing billing related work. Failure to close the service channel may degrade the performance of your app.

RNCustomBilling.open()
.then(() => RNCustomBilling.purchase('YOUR_SKU','DEVELOPER_PAYLOAD',RC_REQUEST))
.then((details) => {
  console.log(details)
  return RNCustomBilling.close()
})
.catch(err => console.log('Vendor err:', err))

purchase('YOUR_SKU','DEVELOPER_PAYLOAD',RC_REQUEST)

Parameter(s)
  • productSKU (required): String
  • developerPayload: String
  • rcRequest: Integer
Returns:
  • Details: JSONObject:
    • mDeveloperPayload:
    • mItemType:
    • mOrderId:
    • mOriginalJson:
    • mPackageName:
    • mPurchaseState:
    • mPurchaseTime:
    • mSignature:
    • mSku:
    • mToken:
RNCustomBilling.purchase('YOUR_SKU','DEVELOPER_PAYLOAD',RC_REQUEST)
.then((details) => {
  console.log(details)
})
.catch(err => console.log('RNCustomBilling err:', err))

consume('YOUR_SKU')

Parameter(s)
  • productSKU (required): String
Returns:
  • Details: JSONObject:
    • mDeveloperPayload:
    • mItemType:
    • mOrderId:
    • mOriginalJson:
    • mPackageName:
    • mPurchaseState:
    • mPurchaseTime:
    • mSignature:
    • mSku:
    • mToken:
RNCustomBilling.consume('YOUR_SKU')
.then(...)
.catch(err => console.log('Vendor err:', err))

loadOwnedItems()

Returns:
  • items: JSONArray:
RNCustomBilling.loadOwnedItems()
.then((details) => {
  console.log(details)
})
.catch(err => console.log('Vendor err:', err))

loadInventory([item1_SKU,item2_SKU,...])

Parameter(s)
  • productSKUs (required): Array
Returns:
  • mPurchaseMap: JSONObject
  • mSkuMap: JSONObject
RNCustomBilling.loadInventory([])
.then(...)
.catch(err => console.log('Vendor err:', err))

Use event listener

Below function dispatch Event instead of Promise and return value is same.

purchaseWithEvent('YOUR_SKU','DEVELOPER_PAYLOAD',RC_REQUEST)

consumeWithEvent('YOUR_SKU')

loadOwnedItemsWithEvent()

import {DeviceEventEmitter} from 'react-native';
...
  componentDidMount(){
    DeviceEventEmitter.addListener('Vendor', function(e: Event) {
      // handle event.
      console.log(e);
    });
  }
