Hi all,

we integrated meta pixel (server side) on our storefront, the connection is established correctly, but seems like meta is not accepting (understanding) the passed parameters of each callout.

I managed to set up code integration with meta, I'm receiving the events, but not sure why I don't see the sent parameters inside the meta configurator. I've set all the matching and also added all the fields I'm sending, getting no error, but Meta still doesn't see the params. For example, the View content is empty, I can only see something for the addToCart call. What is more strange is for testing events everything looks good. When I add the test Code for the callout, the test events are displayed correctly, with all the data.

Sample code, I'm using

https://graph.facebook.com/v19.0/pixelCode/events?access_token=TOKEN

        Map<String, Object> event = new Map<String, Object>();
        event.put('event_name', type);
        event.put('action_source', 'website');
        event.put('event_time', unixTimestamp);
        event.put('user_data', new Map<String, Object>{
            'em' => new List<String>{ hashedEmail }
        });
        event.put('event_source_url', 'myurl.com');

        if (type == 'ViewContent' || type == 'AddToCart') {
            event.put('custom_data', new Map<String, Object>{
                'content_category' => product.Family,
                'content_name' => product.Name,
                'content_ids' => new List<String>{ product.Id },
                'content_type' => 'product'
            });

        } else if (type == 'CompleteRegistration') {
            event.put('custom_data', new Map<String, Object>{
                'content_category' => product.Family,
                'content_name' => product.Name,
                'content_ids' => new List<String>{ product.Id },
                'content_type' => 'product'
            });

        } else if (type == 'Purchase') {
            event.put('custom_data', new Map<String, Object>{
                'currency' => 'EUR',
                'value' => orderTotal
            });

        }

            //Prepare the request body

            List<Map<String, Object>> events = new List<Map<String, Object>>();
            events.add(event);

            Map<String, Object> requestBody = new Map<String, Object>();
            requestBody.put('data', events);

            // Convert the request body to JSON
            String requestBodyJson = JSON.serialize(requestBody);

            httpRequest.setBody(requestBodyJson);
            Http http = new Http();
            HttpResponse httpResponse = http.send(httpRequest);

I also posted a screenshot, where it's visible that the connection is working fine, but even from the event match quality, you can see that my parameters are not matched correctly. What am I doing wrong? I guess it must be somehow related to the meta configuration.
