JSON HTTP Request tag
JSON HTTP Request tag sends a POST request to your URL with a JSON body with all event data that came to the GTM client. There is also an ability to add your custom request headers and data.
Also, tag changes “-” symbol in keys to “_”. That is done because many systems do not work with nested objects and our tag tries to work with all systems out of the box. These transformations apply only to event data that comes from the client. If you use the “Additional Options” setting of the tag, the keys that you fill in will be used without any modification.
