Hi,
The ootb tracking function has fixed usage afaik:
The function's purpose is to make an http get request to the tracking module, with 3 values in the url:
- broadLog id
- delivery id
- 'tag id' - weird name for action taken, e.g. '2' is click.
You can overload tagId with arbitrary data, e.g. json payload, after changing the tracking col type from number to varchar.
Probably better off making a separate service outside tracking to handle custom data though.
Thanks,
