Using MPL (PayPal) and in-app Google play - get payment confirmation from server

diego77

I have an Android app that processes payments through Google Play (in-app billing) and the MPL from PayPal.

After I get an positive result in the activity I call a php script on the server to process the order.

I want the script to check if the payment is verified.

I found some information on the PayPal developers site, but since PHP is pretty new for me, I don't know how to 'translate' all that into PHP. So if there is some snippet somewhere, that would be great.

For google play in-app I should be able to check this POST:

www.googleapis.com/androidpublisher/v1.1/applications/{packageName}/inapp/{productId}/purchases/{token}

I couldn't find what the productId is, but I'm guessing it's the SKU I'm sending, and where to I get the token?

For PayPal, I found:

GET https://api.paypal.com/v1/payments/sale/{id}

curl -s --insecure
-H "X-PAYPAL-SECURITY-USERID: api_username"
-H "X-PAYPAL-SECURITY-PASSWORD: api_password"
-H "X-PAYPAL-SECURITY-SIGNATURE: api_signature"
-H "X-PAYPAL-REQUEST-DATA-FORMAT: NV"
-H "X-PAYPAL-RESPONSE-DATA-FORMAT: NV"
-H "X-PAYPAL-APPLICATION-ID: app_id"
https://svcs.sandbox.paypal.com/AdaptivePayments/PaymentDetails -d
"payKey=AP-3TY011106S4428730
&requestEnvelope.errorLanguage=en_US"

I'm not sure how to use this in PHP and how to deal with the certificate when using this form my server. It also seems like depending on the use of a PayPal account or a credit card you should use different verifications, how do I know which method the user used?

Some example code would help me a lot, I'm using PHP.

For starters, you should probably be more specific about how you "call a php script on the server." I'm guessing that your mobile app is accessing some PHP script's url on your server.

Surely you realize how broad and vague your request is.

What do you mean "for google play in-app?" Do you mean that your application needs to access that url? And what do you mean "I couldn't find what the productId is?" I find it puzzling that you have an app that is performing a purchase but has no idea what it is buying.

You really need to clarify exactly what it is you are trying to do. You've posted a bunch of urls and given vague hints about trying to purchase something with some kind of product or sale id but there's really no question here that can be answered.
