Is your product id employs_5 or 5_employs ??

LaunchPurchaseFlow opens the billing pop-up . Can you check the response code if it is failed to launch the purchase flow ?


I just copy it from google play console and past it in text block


Do you mean in campanion or after downloading from google play?

Hello, I have a question, I made a project where I can sell and release the product, without any problem, but I can’t make it load the user’s purchases, so as soon as the user leaves the screen or closes the app, he has to do the buy again. Could someone help me, I’ve already downloaded the available aia and it’s the same way.

always check the purchased products before doing anything in your app
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.



Extension is updated to version 2.

Changes :

  1. New method AutoAcknowledge & Test is added. They are available in designer property as well.

    If AutoAcknowledge is enabled then After you sucessfully got purchase, you no need to handle purchase manually. It will automatically handle purchase as Non-Consumable ie same product cant be bought again.
    If test is enabled then productId android.test.purchased is used everytime.

  2. Added skuType in LaunchPurchaseFlow method that will open a door to buy subscription too.


  3. Added more parameters in GotPurchasesHistory event block. Now you can get lists of productIds, orderIds & original Jsons.


Documentation has been updated in community aswell as in getaix. You can find changes in source code from Github commits.


Just One Word Awesome And Second Most Usefull Extension For Me

My In App Purchase Working Excellent


Can Anyone Tell Me

How Much Percent % Does Google Play Deduct On Selling Each Products ?

For Me Its 30% But Somewhere I Have Read That Its 15% But Why 30% For Me

Can you check with first version of this extension ?
Here is the download link from github : https://github.com/oseamiya/InAppBilling/releases/download/1.0.0/com.oseamiya.inappbilling.aix

actually i followed the in app billing guide from one post.
But i could not generate apk, so i deleted the extension. and then i was able to generate the apk.

So now i do not any blocks for the extension for now.
I just tried including the extension in app and generating the apk without blocks and could not generate the apk.
I tried this 3-4 times.
Everytime after deleting the extension the apk generates without any errors

Did you tested with this version of the extension ?
