This specification offers a way for XMPP entities to list the accepted responses to a message, so that entities that receive such a list can offer convenient UI to quickly respond with one of the allowed responses. Additionally, this specification provides a way for entities to provide generic actions in similar fashion to quick responses.</p>

|

<p>All message bodies SHOULD always list the (internationalized) allowed responses too, so that users of clients that don't support &xepname; can still know what the allowed responses are.</p>
|
||||
<p>Bots or other entities that indicate allowed responses are free to accept variations of the response values for convenience, for example ignoring the casing or accepting abbreviations of response values.</p>
|
||||
<p>Actions SHOULD only be a quicker way to access a feature that could also be accessed using information in the message body. For example, a bot that notifies about a new merge request includes in its notification message body a link to the web interface where manual merging is possible. An action could offer a more convenient way to merge, without taking the route via the web interface. In summary, users of clients that don't support &xepname; SHOULD still have a way to manually trigger the action.</p>
|
||||
<p>Clients MUST only provide quick responses for the most recently received message that contains text content.</p>
|
||||
<p>Clients MUST only provide action selection for the most recently received message that contains actions. This is slightly different than the rule for quick responses, in that the message defining the action does not have to be the most recent message with text content, but only the most recent message that contains actions.</p>
|
||||
<p>Clients MAY decide to not offer action selection if the message containing the action is not the most recent message with text content.</p>
|
||||
<p>It is up to the client and its specific UI requirements to decide what to do if both quick responses and actions are available, potentionally coming from different messages.</p>
