Buttons
buttons and suggestions are a great way to transition through your flow. They are rendered differently depending on the integration.
Suggestions are suggested responses that you can output to the user. When the user selects a suggestion, it comes in as if the user typed the text.
Buttons are a more advanced way to transition through the flow, link to a webpage or start a new flow.

Suggestion
When clicked, it's as if the user typed the text. See the button support matrix for the integrations that support suggestions. Suggestions are rendered on Messenger as quick replies.
suggestions:
- African Elephant
- Asian Elephant
- Woolly MammothButtons
There are 3 main types buttons: transition buttons, link buttons and start buttons. Transitions move you through the flow, links are links to webpages and start buttons start new flows.
There are 4 more buttons available only on Facebook Messenger: account_link, account_unlink, share and location (rendered as a quick_reply).
