How get information about an already signed subscription? (Android)

[yuriydrobniy]

Hey guys!
Could someone help me with question.
How can I get information about an already signed subscription?
My goal is to get the price of this subscription. And the problem is that we only have the productId to determine which subscription is purchased. But in Google Play Billing Library V5 we have multiple offers with unique offerTokens under the same productId.

Im using react-native-iap: 9.0.0

@yuriydrobniy Do you mean that you want to know what offerToken you used to purchase a given productId? If so, have you considered using developerPayload?

@andresesfm any other ways in your mind?

Since developerPayload is not pretty accurate, of course it's better than storing it in DB, but anyway.

As far as I see it doesn't exist in BillingLibrary itself, correct me if I'm wrong.

@professorkolik can you please elaborate on developerPayload not being accurate? It's a string whatever you set is what you get back. I'm curious, let me know

@andresesfm First of all as far I can see developPayload is deprecated from BillingClient v3 according to this reference
Second I feel it's not related to developer (responsibility vice) to pass offerToken, which I would expect should come in Purchase data. It's actually strange that Google doesn't provide it out of the box (as far as I can see the docs)

And the 3d even when we pass developerPayload in finishTransaction it doesn't exist then in availablePurchase (we acknowledge purchase on BE with help of Real-time developer notifications)

I can't think of a better option than storing it in your backend. even developerPayload was more of a hack
