Tips & Gotchas

• Forum mode must be enabled on the supergroup. The chat must have topics turned on in group settings — the method fails silently otherwise.
• icon_color accepts only 6 specific integer values. Valid options: 7322096 (blue 0x6FB9F0), 16766590 (yellow 0xFFD67E), 13338331 (purple 0xCB86DB), 9367192 (green 0x8EEE98), 16749490 (pink 0xFF93B2), 16478047 (red 0xFB6F5F).
• Get valid icon_custom_emoji_id values from getForumTopicIconStickers. Not all custom emoji work as topic icons — only those returned by that method are permitted.
• Save message_thread_id from the returned ForumTopic. You need it to send messages into the topic, close it, or delete it later.
• In private chats, bots can always create topics without admin rights. This is useful for organizing per-user conversations.
• The can_manage_topics right is required in supergroups — even if the bot has other admin rights, this specific permission must be granted.
