Message size limit for Facebook messenger bot

Question

I am trying to implement a Facebook messenger bot. I have trouble with the bot replying with a response that contains large amount of words. Is there a limit to the number of words that can be used in a response?

P.S : It works fine otherwise

Curagh

Answer 1

As described in the doc, text message must be UTF-8 and has a 2000 character limit.

There are other restrictions in template for field title, subtitle & call-to-actions button.
