WhatsApp environment have some limitations that you need to keep in mind when building the bot:

  • GIF and SVG image files are not supported. They won’t be displayed.

  • Buttons content can’t be longer than 20 characters. If the content is longer, it will be truncated.

  • WhatsApp only allows to display 3 buttons at a time. So we work around that by adding ”…” messages to display more buttons.

  • Incompatible blocks, if present, they will be skipped:

    • Payment input block
    • Chatwoot block
    • Script block
    • Google Analytics block
    • Meta Pixel blocks
    • block

Contact information

You can automatically assign contact name and phone number to a variable in your bot using a Set variable block with the dedicated system values:

Start bot condition: A condition that will be evaluated when a user starts a conversation with your bot. If the condition is not met, the bot will not be triggered.
