Sending transactional mail from third party site

So do we simply need to create an email with a Product card block, add tokens there to get the image URL/price/description/etc, and send the info to Mautic through API?

And tokens must be specified here:

 "dynamicContent":[  
      {  
        "tokenName":null,
        "content":null,
        "filters":[  
          {  
            "content":null,
            "filters":[  
              {  
                "glue":null,
                "field":null,
                "object":null,
                "type":null,
                "operator":null,
                "display":null,
                "filter":null
              }
            ]

Just need it clarified as you answered in another discussion that for the native dynamic content we can’t use a structured source, like a JSON. I’m new with Mautic :face_with_peeking_eye:
