Character limits

When building your bot, there are a few character limits to consider.

Text parts

A text message part can consist of up to 640 characters of text. Remember, the text should not be too dense – break it up into small chunks of a few sentences with a short delay in between. We recommend for long chunks of text to add a delay of 500ms per line of text.

Quick replies and buttons

You can also add up to three buttons or 13 quick replies to a text part. There is a limit of 20 characters per button and quick reply.

Carousels

Carousels can contain up to three kinds of text - the title, the subtitle and the button. The subtitle and button are optional. The title and subtitle have a limit of 80 characters each, whilst the button has a limit of 20 characters.
