Direct Line API - Bot Framework / Hero Cards and Attachments

Question

I just started using the Direct Line API (1.1) and I saw that it doesn't let you know if a conversation was showed inside a Hero Card or a Button for example.

 {
      "id": "fBPDq9JSeL|000000000000000004",
      "conversationId": "fBPDq9JSeL",
      "created": "2016-11-28T20:22:20.6035604Z",
      "from": "portosegurobot",
      "text": "Health For Pets\n\nNossa missão é proporcionar a cães e gatos uma vida mais saudável e feliz.\n\nAcesse e saiba mais\n\n(Acesse) https://health4pet.com.br/",
      "images": [],
      "attachments": [],
      "eTag": "W/\"datetime'2016-11-28T20%3A22%3A21.3990939Z'\""
    }

The code above was showed (in the emulator) in a hero Card with a Button (card action). The Direct Line API doens't flag that? Is there a way?

Answer 1

Hero cards / attachments are not supported in DirectLine v1.1; you won't receive anything in the attachments collection.

If you want to support Cards, you might have to do something custom as shown in the DirectLine sample. There, the bot is sending the hero card through the ChannelData field and the client is parsing that accordingly.

I haven't used DirectLine v3.0, but based on the documentation it seems that now attachments might be supported so you might want to take a look to that.
