InlineQueryHandler

class telegram.ext.InlineQueryHandler(callback, pattern=None, block=True, chat_types=None)

Bases: telegram.ext.BaseHandler

BaseHandler class to handle Telegram updates that contain a telegram.Update.inline_query. Optionally based on a regex. Read the documentation of the re module for more information.

Warning

• When setting block to False, you cannot rely on adding custom attributes to telegram.ext.CallbackContext. See its docs for more info.

• telegram.InlineQuery.chat_type will not be set for inline queries from secret chats and may not be set for inline queries coming from third-party clients. These updates won’t be handled, if chat_types is passed.

Examples

Inline Bot

Available In

telegram.ext.Application.handlers

Parameters:

• callback (coroutine function) –

  The callback function for this handler. Will be called when check_update() has determined that an update should be processed by this handler. Callback signature:

  async def callback(update: Update, context: CallbackContext)
  

  The return value of the callback is usually ignored except for the special case of telegram.ext.ConversationHandler.

• pattern (str | re.Pattern, optional) – Regex pattern. If not None, re.match() is used on telegram.InlineQuery.query to determine if an update should be handled by this handler.

• block (bool, optional) –

  Determines whether the return value of the callback should be awaited before processing the next handler in telegram.ext.Application.process_update(). Defaults to True.

• chat_types (list[str], optional) –
