PHP Postback URL

[Smart]

should my postback php file look like this?

this is to buy a pizza for $0.50

my concern is that this seems to only cater for one item I also would
like to sell hotdogs for $0.20


<?php
$payload = array(
"iss" => $sellerIdentifier,
"aud" => "Google",
"typ" => "google/payments/inapp/item/v1",
"exp" => time() + 3600,
"iat" => time(),
"request" => array (
"name" => "pizza1",
"description" => "yum yum"
"price" => "0.50",
"currencyCode" => "USD",
"sellerData" => "",
)
);
$pizzaToken = JWT::encode($payload, $sellerSecret);
?>

Hi,

Please keep in mind that the In-App Payments API is only for digital goods.

If you sell virtual hotdogs and pizza inside a game you are fine :-)

You can bundle as many virtual items as you want in one JWT. 

Thanks,

Mihai

Also as an FYI with the JWT PHP library:

In JWT.php change 

$json = json_encode($input);

to

$json = json_encode($input, JSON_UNESCAPED_SLASHES);

otherwise you get some \/ s

I think you miss understand me... I need people to choose between more
than one item, not to buy multiple items in the same transaction.

In any case; the docs do not say how to do this!

postback.php
require_once 'JWT.php';

JWT.php
$json = json_encode($input, JSON_UNESCAPED_SLASHES);

Uh oh. There was a problem.

Something else is probably wrong.  Try decoding your jwt with atob in a chrome developer tools.

[Smart]

I used your tool to create the jwt:

In-App Payments demo
https://checkout.google.com/customer/gadget/inapp/demo.html?hl=en_US

what the hell is atob?

You're probably purchasing from yourself then, create a separate buyer account

Follow the dev guide instead of copying and pasting for instructions on defining dynamic items

https://developers.google.com/in-app-payments/docs/tutorial#2

Atob is a tool for base64 encoding/decoding:

I'm not buying from myself, I have a separate account. you should know
that google wallet stops you from completing the transaction when
attempting to buy from yourself.

I have 'only' studied this page:
https://developers.google.com/in-app-payments/docs/tutorial#2

I will try atob now that I know where/what it is. thanks

window.atob: produces [Object Object]


I tried encoding my jwt using window.btoa like this:

google.load('payments','1.0',{'packages':['production_config']});
function purchase(){
var encodedData = window.btoa({"iss":"02------
secret------94","aud":"Google","typ":"google/payments/inapp/item/
v1","iat":1329362137,"exp":1329448537,"request":
{"currencyCode":"USD","price":"0.01","name":"penny","sellerData":"","description":"none"}});
goog.payments.inapp.buy({
    jwt: encodedData,
    success: function() { window.alert('success')},
    failure: function() { window.alert('failure')}
  })
}

and I get this wallet error:

Uh oh. There was a problem.

We couldn't start your purchase because of a technical issue.

Details of the problem below:

Looks like there is an error in the setup for your purchase. Please
contact the merchant with this error message: Expected 3 components in
jwt: W29iamVjdCBPYmplY3Rd



!?

Thanks
