Possible to use a single function from react-native-IAP?

[mj-schmitz]

Hello, I have implemented expo-IAP in my app and can purchase the subscription. However, there is no way to check subscription status using EXPO. I am hoping to use this react-native-IAP package so I can simply call subscriptionStatus using storekit2 and check the status. That is the only thing I wish to implement.

Is it possible to simply call this so I can get a true/false?

Here is the current implementation I have, and I get undefined when trying to read it.:

import { useIAP, endConnection,initConnection,IapIosSk2, setup} from "react-native-iap"

async nativeTest() : Promise<any>{
        setup({storekitMode:'STOREKIT2_MODE'})
        await initConnection()
        const status = await (IapIosSk2).subscriptionStatus('sku')

        console.log((JSON.stringify(status) + 'status'))
        await endConnection();

        return status

    }

and if I don't stringify, I get the following :

{"_1":0,"_2":0,"_3":null,"_4":null}status
or
undefinedstatus

Is there a way to do this without implementing an entire workflow for IAP?

try getting products/subscriptions before subscriptionStatus

I'm able to successfully get both and have implemented the logic for purchasing the subscription via the source code in the subscription screen example.

Here's what I'm trying now :

`

const isSubbed = () => {

      console.log('awaiting subbed')

      IapIosSk2.subscriptionStatus('subscriotion sku').then((res)=>{

        res.map((result) => {
          console.log('status Success: ',result)
        })
      }).catch( ()=>{
        console.log('failed to get status')
      })
}

`

and then I render a button to call onpress={isSubbed}

I am now getting returned with failed to get subscription status via the rejected promise.

Am I using the wrong 'sku'? Should it be the subscription sku that is in the app store, or the app sku?

[mj-schmitz]

I have fixed what I thought was the problem with my handling of the promise. Here is the code I would assume to work:

const isSubbed = () => {
        console.log('awaiting subbed')
        return IapIosSk2.subscriptionStatus('subscription sku').then(res=>{
          console.log('returned: ', res)
          return res
        }).catch( ()=>{
          console.log('failed to get status')
        })
    }
   
    isSubbed().then(res=>{
      console.log(res + 'res')
    })

However, this also gives undefined. What is the sku I should be putting into the function, this should return the value correct?

Not sure if you saw my earlier comment but, have you called getProducts/getSubscriptions before calling subscriptionStatus ?

[mj-schmitz]

Yes I saw it, I am able to succesfully get, display, and purchase my subscriptions (essentially the same as the subscription example in the source code) But when I put the above function before the return statement and after the getProducts/getsubscription functions, I get undefined.

[andresesfm]

It all comes down to this line: https://github.com/dooboolab/react-native-iap/blob/main/ios/RNIapIosSk2.swift#L762 The reasons I can see status being nil are that a) sku in products[sku]doesn't match the one you used forgetsubscriptions. b) you didn't call getSubscriptions hence products is nil c) The sku you are querying is not a subscription. Let us know, I home that this helps

[mj-schmitz]

Thank you for the response. I'm confused however as to why in b) getSubscriptions would fill products? I thought this would fill subscriptions. I do not have any products but I do have the subscription field and am mapping the results to the screen.

Is having a product necessary? I am under the assumption that for renewable subscriptions, I only need the getSubscriptions that grabs it from the app store. I was able to create a test product in app store and get the product details just to make sure, and the status is still coming undefined.

I can't seem to find any example code of subscriptionStatus, but it seems like what I have should surely work, as I am using the same SKU for getSubscriptions as i am for subscriptionStatus.

[andresesfm]

products is just the variable name that holds both products and subscriptions on the native module.

Sorry, there's no example of this method as it's new for sk2. It's a good chance for a contribution
