Support for adaptive cards
The following table lists the rich cards that are supported across different channels when you're using bots. The support categories are intentionally broad because many possible combinations of cards, features, and channels are applicable. We recommend that you use the information in the table as a base reference, and test each of your cards in the required channels.
| Channel | Hero card | Thumbnail card | Audio card | Card carousel |
|---|---|---|---|---|
| Microsoft Teams | ✔ | ✔ | ✖ | ✔ |
| LINE | ✔ | ✔ | 🌐 | ✔ |
| Custom (Direct Line) | ✔ | ✔ | ✔* | ✔* |
✔: Supported; card is supported fully with the exception that some channels support a subset of the card actions. The number of actions allowed on each card might be limited that varies by channel.
✔*: Card elements are supported in the Webchat version of custom channel that uses Direct Line, but not in the Android version.
🌐: Card is converted to unformatted text, links might not be active, images might not be displayed, or media might not work. The behavior might vary by channel.
✖: No support
The markdown element for adaptive cards is partially supported across all chat channels. For example, the markdown element isn't supported in live chat, whereas, it's supported in LINE.
Media or audio card and date input elements for adaptive cards are only supported in Live chat channels. Adaptive card elements like text block and images are also supported across channels.
The Apple Messages for Business, SMS, and WhatsApp social channels don't support any cards listed in the preceding table.

Note
- For Microsoft Teams, when a customer sends an emoji from the Teams client, the agent receives a PNG image. When an agent sends a GIF image (outbound), the customer will receive a PNG image.
- The custom channels that use Direct Line support different types of file attachments, but it's up to the client to implement them.
- For LINE inbound and outbound messages, when a GIF image is sent, the recipient will receive a JPG image.
- For WhatsApp messages, when a customer sends an attachment in document format (for example, a DOCX, XLSX, or TXT file), the agent will receive the attachment name as message text. We recommend converting documents to PDF format before sending them as attachments.
- For newly created Twilio accounts, you must disable a security setting that blocks the ability to send media files. More information: Extended notice and update on security changes: HTTP Authentication for Voice and Messaging Media enabled by default
