[Question] sendBranchEvent add contentItems

[tienne]

From the document, there seems to be no way to add contentMetadata in sendBranchEvent, is there any other way?

[adrianyg7]

Hi @tienne please refer to track events section
BranchDeepLinks.sendBranchEvent({ eventName, metaData })

[tienne]

Please refer to this PR #39
I added contentMetadata in metaData because it was not being handed over to the event.

When i use contentMetadata the numeric values are converted into string. Because of that a 400 is raised.

Sample content_item from JS to branch:

{
    "$content_schema": "COMMERCE_PRODUCT",
    "$sku": "8753548787967",
    "$product_name": "Girls Alphabet Printed T-Shirt With Flower Printed Pants Set",
    "$price": 629,
    "$quantity": 1,
    "$currency": "INR",
    "$product_brand": "Foshan Chancheng District",
    "$product_category": "Sets",
    "$product_variant": "45759769575679",
    "$og_title": "Girls Alphabet Printed T-Shirt With Flower Printed Pants Set",
    "$og_image_url": "https://cdn.shopify.com/s/files/1/0646/0211/2255/files/15000617-4196-4092-ab5c-cc41190490adO1CN01hLYMIo1Jm6jwWEyfe__21_212214886431070-0-cib.jpg?v=1743069482",
    "$canonical_identifier": "girls-alphabet-printed-t-shirt-with-flower-printed-pants-set-474807"
}

Posted content_item from logcat:

{
      "$product_category": "Sets",

      "$product_variant": "45759769575679",
