Is there any way to validate google play transaction with REST?

General

I want to make transactions and validate them through backendless. How can I do that?

I found this article but it only works with Java SDK

Hi Timur,

I am still checking if there is REST API. Out of curiosity, could you please describe why the implementation in our SDK for Android would not work for you?

Hi Timur,

Sure there is a REST API.

Here are the routes for v4:

Validate Purchase: GET /<app_id>/&lt;rest_api_key&gt;/commerce/googleplay/validate/&lt;package_name&gt;/inapp/&lt;product_id&gt;/purchases/&lt;token&gt;
Get Subscription Status: GET /<app_id>/&lt;rest_api_key&gt;/commerce/googleplay/&lt;package_name&gt;/subscription/&lt;subscription_id&gt;/purchases/&lt;token&gt;
Cancel Subscription: POST /<app_id>/&lt;rest_api_key&gt;/commerce/googleplay/&lt;package_name&gt;/subscription/&lt;subscription_id&gt;/purchases/&lt;token&gt;/cancel

And for v3:

Validate Purchase: GET /&lt;version_name&gt;/commerce/googleplay/validate/&lt;package_name&gt;/inapp/&lt;product_id&gt;/purchases/&lt;token&gt;
Get Subscription Status: GET /&lt;version_name&gt;/commerce/googleplay/&lt;package_name&gt;/subscription/&lt;subscription_id&gt;/purchases/&lt;token&gt;
Cancel Subscription: POST /&lt;version_name&gt;/commerce/googleplay/&lt;package_name&gt;/subscription/&lt;subscription_id&gt;/purchases/&lt;token&gt;/cancel

Hello! I don’t want to implement any additional sdks in my project. They makes app bigger and slower in some way

Thanks! But where can I find the explanation of mechanism “under the hood”? For example, I want to check any in-app purchases though Backenless. After payment I want to increase some value in table. What should I do?
