GramIO Usage

// Context shorthand — reopens the General topic in the current chat
// (chat_id is injected automatically from the context)
bot.on("general_forum_topic_hidden", async (ctx) => {
  await ctx.reopenGeneralTopic();
});

// Direct API call with explicit chat_id
await bot.api.reopenGeneralForumTopic({ chat_id: -1001234567890 });

// Reopen the General topic in the current chat via command
bot.command("opengeneraltopic", async (ctx) => {
  await bot.api.reopenGeneralForumTopic({ chat_id: ctx.chat.id });
  await ctx.reply("General topic has been reopened.");
});

// Reopen General topic by supergroup username
await bot.api.reopenGeneralForumTopic({ chat_id: "@mysupergroup" });

Errors

Code	Error	Cause
400	`Bad Request: chat not found`	`chat_id` is invalid or the bot is not a member of the chat
400	`Bad Request: TOPIC_NOT_MODIFIED`	The General topic is already open — no state change needed
400	`Bad Request: method is available only for supergroups`	The target chat is not a supergroup with forum mode enabled
403	`Forbidden: not enough rights`	Bot lacks the `can_manage_topics` admin right — required without exception for the General topic
429	`Too Many Requests: retry after N`	Rate limit hit — check `retry_after` and use the auto-retry plugin

Tips & Gotchas

Automatically unhides the topic. Unlike reopenForumTopic, calling reopenGeneralForumTopic also unhides the General topic if it was previously hidden with hideGeneralForumTopic. You do not need to call unhideGeneralForumTopic separately.
can_manage_topics is always required. Unlike regular forum topics where the bot can manage topics it created, the General topic always requires the can_manage_topics admin right — there is no creator exemption.
Forum mode must be enabled. This method only works in supergroups where the "Topics" (forum) feature is turned on. Calling it on a regular group or channel returns an error.
Context shorthand ctx.reopenGeneralTopic() automatically fills chat_id from the current message context — use it inside message/update handlers for cleaner code.
The General topic is special. Unlike other topics it cannot be created or deleted — only opened, closed, hidden, and unhidden. Manage it with the dedicated *GeneralForumTopic methods.
