Note: It has been posed already in the post: Quantities of items are not tracked in google analytics transactions but not answered.
When using Google Tag Manager ([edit] Release Version 3.06) for iOS (Objective-C) and sending a purchase event like described in the example the event gets send and I can read it back in the Google Analytics backend, however the value for quantity is always 0 (zero). The price is 0 (zero) as well, but I'm not sure if this is caused by the quantity being 0. Every other parameter seems to be sent just fine.
Note that I implemented the android SDK with no problems.
The code as it is now is (altered for readability):
int quantity = 1;
float price = 0.89f;
float shipping = 0.0f;
float tax = 0.0f;
TAGDataLayer *dataLayer = [TAGManager instance].dataLayer;
NSMutableArray *purchasedItems = [NSMutableArray array];
[purchasedItems addObject:@{@"name": GetStringParam(name),
@"sku": GetStringParam(SKU),
@"category": GetStringParam(category),
@"price": [NSNumber numberWithFloat:price],
@"currency": @"EUR",
@"quantity": [NSNumber numberWithInt:quantity]
}];
[dataLayer push:@{@"event": @"Transaction",
@"transactionId": GetStringParam(transactionID),
@"transactionTotal": [NSNumber numberWithInt:quantity],
@"transactionAffiliation": GetStringParam(affiliation),
@"transactionTax": [NSNumber numberWithFloat:tax],
@"transactionShipping": [NSNumber numberWithFloat:shipping],
@"transactionCurrency": @"EUR",
@"transactionProducts": purchasedItems
}];
[dataLayer push:@{@"transactionId": [NSNull null],
@"transactionTotal": [NSNull null],
@"transactionAffiliation": [NSNull null],
@"transactionTax": [NSNull null],
@"transactionShipping": [NSNull null],
@"transactionCurrency": [NSNull null],
@"transactionProducts": [NSNull null]
}];
Am I doing something wrong or is the a known issue for the GTM SDK for iOS? I would really love to get some help on this.
UPDATE: Just wanted to add the log that GTM generates:
Saved hit: {

If any additional info is needed, please let me know.
