messages.getCustomEmojiDocuments#d9ab0f54 document_id:Vector<long> = Vector<Document>;Custom emojis are a special kind of entity », containing just a document_id, which can be passed to messages.getCustomEmojiDocuments to fetch the static, animated or video sticker emoji that should be displayed to the user as described in the stickers documentation.
Custom emoji documents will contain documentAttributeCustomEmoji attribute instead of a documentAttributeSticker, containing information on the associated emoji (alt), whether the emoji can be used by non-premium users (free) and the associated stickerset.
If the documentAttributeCustomEmoji.text_color flag is set, the color of this TGS custom emoji should be changed to the text color when used in messages, the accent color if used as emoji status, white on chat photos, or another appropriate color based on context.
Note that when sending messages with attached custom emojis, the messageEntityCustomEmoji entity » must wrap exactly one regular emoji (the one contained in documentAttributeCustomEmoji.alt) in the related text, otherwise the server will ignore it.
Like stickers, custom emojis are organized in stickersets: see the stickers documentation » for more info on how to work with them.
To send a message with one or more custom emojis, create and attach messageEntityCustomEmoji entities » to a message.
Note that you can attach a maximum of message_animated_emoji_max custom emojis, as specified by the appConfig field ».
The custom emoji selection UI should offer a list of categories to quickly filter results by a (list of) emojis, or by some other criteria, see here » for more info.
