A Telegram channel that publishes through a shared system physically shares the same bot with hundreds of other channels on the platform. While there are only a few publications, this is not noticeable: messages are sent on time, media loads without delays, everything works as it should. However, the Telegram Bot API has strict limits on the number of requests from a single bot in a given time frame β and these limits are shared among all who publish through this bot, rather than being personal for each channel.
We encountered this in practice not because we were looking for a problem in advance, but because several active channels simultaneously published posts with media files at roughly the same time β and some publications were delayed, which could only be explained by the shared queue of requests on the system bot's side. An investigation revealed a logical fact: the activity of others during peak load times directly affects the speed of publication for your channel, even if you publish rarely and carefully. Worse still β if some channel on the platform triggers Telegram's suspicion of spam (for example, by sending too many identical messages), the entire bot could theoretically be subjected to temporary restrictions, including channels that are completely unrelated.
The solution to this problem is a custom Telegram bot: your own bot, tied only to your channel, which does not share limits and reputation with anyone else.
How the System Bot Differs from the Custom Bot
The system bot in Telematic is a ready-made "out of the box" solution: there is no need to create or configure anything, publication works immediately after connecting the channel. This is a great option for starting out and for channels with a low frequency of publications, where the risk of hitting shared limits is minimal.
A custom bot is a separate Telegram bot created specifically for your channel through BotFather, with a token that is entered into the channel settings within Telematic. From this moment on, all publications, comments, and any other actions on behalf of the channel go through this separate bot, rather than the shared one. The rate-limit becomes a personal resource for the channel, rather than a common pool that is distributed among all users of the platform.
When the System Bot is No Longer Sufficient
There are several clear signals that it is time to switch to your own bot.
High Frequency of Publications. If the channel publishes several posts a day, especially with media files (videos, images), the likelihood of encountering the shared queue increases proportionally to the load of all other channels on the system bot at that same moment.
Critical Timing of Publication. If it is important for the channel that a post is published at a specific minute β for example, synchronously with publication on other platforms β any delay from the shared queue becomes a problem, rather than just an inconvenience.
Commercial Significance of the Channel. For a channel that generates primary traffic or income, the risk of temporary bot blocking due to others' activity is a risk that should be completely eliminated, rather than considered an acceptable side effect of free infrastructure.
Extended Publication Rights. For certain scenarios β for example, publishing in specific types of groups or with extended moderation settings β a bot with individually configured rights may be required, which is inconvenient or impossible to grant to the shared system bot.
How to Set Up a Custom Bot
The connection process does not require programming. A new bot is created through BotFather in Telegram using the /newbot command, the bot is assigned a name and username, after which BotFather issues a unique access token. This token needs to be entered into the configuration of the specific channel in Telematic settings β from this moment on, publication for this channel automatically switches to the custom bot, without any additional actions for each individual publication.
An important nuance that is easy to overlook: if the channel uses the auto-publishing feature for the first comment in a linked discussion group, the bot must be added there as a participant β this applies to the custom bot just as it did to the system bot. Changing to your own bot does not negate this requirement, but rather transfers it: now the new bot must be a member of the required group, otherwise the first comment will not be able to be sent.
Another detail worth keeping in mind for security reasons: the token of your own bot is sensitive data, essentially equivalent to a password for the bot. In the Telematic interface, it is masked after saving and will not be displayed in plain view again β this is standard protection, not an interface error, if you cannot "view" the already saved token once more.
What Does Not Change When Switching to Your Own Bot
Changing the bot is purely an infrastructural solution; it does not affect the logic of content generation, scenarios, or publication schedules. Everything that is set up for the channel β platform text, language, CTA funnel, autopilot β continues to work unchanged. Only the technical pipeline through which messages are physically sent to Telegram changes, and with whom the channel shares API limits.
It is also important to understand that the first comment and all regular publications continue to come from your channel's name visually just as before β subscribers will not notice a difference in how the bot appears in the Telegram interface, provided the name and avatar are set up correctly.
Should You Switch Immediately for All Channels
Not necessarily. For a small channel with infrequent publications, the system bot is a working and sufficient solution, and creating a separate bot for a channel with a couple of posts a week is excessive. But as soon as the frequency of publications increases, and the channel becomes a significant source of traffic or income, a custom bot ceases to be a "future" option and becomes insurance against others' mistakes on the shared infrastructure β those very mistakes that you cannot control, but which can cost you a delayed or failed publication at the most inconvenient moment.
