Meta App Events

App Events for Collaborative Ads - iOS

Collaborative Ads allows producers, such as consumer-packaged goods advertisers to run ad campaigns to drive people to seller platforms. Such platforms include online retailer websites or apps and those that can measure, retarget, and optimize towards people who have interacted with the producers' products on the seller platforms. Access to the Collaborative Ads features is provided on a limited basis only. Please contact your Facebook Representative.

To use Collaborative Ads features, the sellers need to implement the following required standard events with their respective parameters. If you're not familiar with app events and parameters, or you need to set up Facebook SDK for iOS, see Getting Started with App Events for iOS.

Examples

ViewContent Event

[FBSDKAppEvents logEvent:FBSDKAppEventNameViewedContent
    valueToSum:54.23
    parameters:@{ FBSDKAppEventParameterNameCurrency    : @"USD",
                  FBSDKAppEventParameterNameContentType : @"product",
                  FBSDKAppEventParameterNameContent     : @"[{\"id\": \"1234\", \"quantity\": 1}]";

Or, with minimal parameters:

[FBSDKAppEvents logEvent:FBSDKAppEventNameViewedContent
    valueToSum:54.23
    parameters:@{ FBSDKAppEventParameterNameCurrency    : @"USD",
                  FBSDKAppEventParameterNameContentType : @"product",
                  FBSDKAppEventParameterNameContentID   : @"1234";

Note: The minimal parameter setup is valid for ViewContent only and not valid for AddToCart and Purchase.

AddToCart Event

[FBSDKAppEvents logEvent:FBSDKAppEventNameAddedToCart
    valueToSum:54.23
    parameters:@{ FBSDKAppEventParameterNameCurrency    : @"USD",
                  FBSDKAppEventParameterNameContentType : @"product",
                  FBSDKAppEventParameterNameContent     : @"[{\"id\": \"1234\", \"quantity\": 2}, {\"id\": \"5678\", \"quantity\": 1}]" } ];

Purchase Event

[FBSDKAppEvents 
    logPurchase:54.23
    currency: @"USD"
    parameters:@{ FBSDKAppEventParameterNameContentType : @"product",
                  FBSDKAppEventParameterNameContent     : @"[{\"id\": \"1234\", \"quantity\": 2}, {\"id\": \"5678\", \"quantity\": 1}]" } ];

Common Mistakes

  • Content: "[\"id\": \"SKU-123\"}, {\"id\": \"SKU-456\"}]" - Missing quantity key.
  • ContentID: "SKU-123,SKU-456,SKU-789" - Missing an array symbol.
  • ContentID: [] - Missing SKU IDs in an array.
  • ContentType: "soap" - The value is not "product".
  • Currency: "$" - Cannot use a currency symbol format.
  • valueToSum: "5000,00" - Wrong format (should not be a string with comma).
