Cross-posting by Telegram forum topics
Pinpoint cross-posting — from or to the forum topic you need.
The problem
A Telegram forum has dozens of topics, but you only need to cross-post one — for example, 'Announcements'. Without filtering by topic, the whole chat flies to the channels: chatter, discussions, off-topic.
How Crosslybot solves it
Crosslybot can work with forum topics in a pinpoint way. You can listen to a specific topic as a source and publish to a specific topic as a target — the rest of the forum is untouched.
Crosslybot can work with Telegram forum topics in a pinpoint way. You can specify a particular topic as a source — only it goes into cross-posting, while chatter and off-topic from other topics stay in the forum.
If the target is also a forum, publishing goes into the specified topic, not the general feed. Additionally, the admin filter and skipping replies work. Cross-posting runs pinpoint between the topics you need, and only relevant content goes to the channels.
How to set up
Add the bot to the forum
Add @Crosslybot to the Telegram forum and grant it admin rights.
Specify the source topic
In the source settings, specify the ID of the forum topic you need — only it goes into cross-posting.
Specify the target topic
If the target is also a forum, specify the ID of the topic to publish into.
Done
Cross-posting runs pinpoint between the topics you need, without touching the rest of the forum.
What's inside
A topic as a source
Only the specified forum topic is listened to — chatter and off-topic from other topics don't get into cross-posting.
A topic as a target
Publishing goes into a specific topic of the target forum, not the general feed.
Topic filters
Additionally, the admin filter and skipping replies work — only the right content goes into cross-posting.
Result
Cross-posting runs pinpoint between the topics you need. The forum stays a forum, and only relevant content goes to the channels.
FAQ
How do I find a forum topic's ID?
The topic ID is visible in a link to a message in the topic — the last number in a URL like t.me/group/42.
Can I listen to several topics?
Each source listens to one topic. For several topics, set up several sources or projects.
Does the admin filter work in a forum?
Yes. In a forum you can take only admins' messages and skip replies — together with the topic filter.
