editForumTopic — Botlify Cloud Docs

Use this method to edit name and icon of a topic in a forum supergroup chat or a private chat with a user. In the case of a supergroup chat the bot must be an administrator in the chat for this to work and must have the can_manage_topics administrator rights, unless it is the creator of the topic. Returns True on success.

PHP — Call editForumTopic on Botlify Cloud

<?php
// ── Botlify Cloud .env — auto-injected, never hardcode secrets ──
$BOT_TOKEN     = getenv('BOT_TOKEN');     // Telegram bot token from @BotFather
$ADMIN_CHAT_ID = getenv('ADMIN_CHAT_ID'); // Your numeric admin Telegram user ID
$BOT_USERNAME  = getenv('BOT_USERNAME');  // Bot username without @

$resp = bot('editForumTopic', [
    'chat_id' => $chatId,
    'message_thread_id' => 'value',
]);

if ($resp['ok'] ?? false) {
    $result = $resp['result']; // handle the response
}

Botlify Cloud Runtime
Credentials are auto-injected in .env — always load them with getenv(): BOT_TOKEN, ADMIN_CHAT_ID, BOT_USERNAME. Main database: database.db (SQLite, WAL mode). Runtime errors: error.log. Quick test: send to $ADMIN_CHAT_ID. Full details: Runtime Reference.
