# Method: messages.setBotCallbackAnswer

Back to methods index

Set the callback answer to a user button press (bots only)

# Parameters:

Name Type Description Required
alert Bool Whether to show the message as a popup instead of a toast notification Optional
query_id long Query ID Yes
message string Popup to show Optional
url string URL to open Optional
cache_time int Cache validity Yes

# Return type: Bool

# Can bots use this method: YES

# MadelineProto Example (now async for huge speed and parallelism!):

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$Bool = $MadelineProto->messages->setBotCallbackAnswer(['alert' => Bool, 'query_id' => long, 'message' => 'string', 'url' => 'string', 'cache_time' => int, ]);

Or, if you’re into Lua:

Bool = messages.setBotCallbackAnswer({alert=Bool, query_id=long, message='string', url='string', cache_time=int, })

# Return value

If the length of the provided message is bigger than 4096, the message will be split in chunks and the method will be called multiple times, with the same parameters (except for the message), and an array of Bool will be returned instead.

# Errors
