Synchronize Telegram and CRM contacts

Telegram restrictions do not allow you to write more than 15 new contacts per day. If contacts have already been added to the mobile device and are accordingly displayed in Telegram, then this restriction ceases to apply.
Set up synchronization with your CRM system to quickly export contacts to your mobile device.

• When synchronizing contacts, keep in mind that a contact may have a hidden phone number in the Telegram Privacy Settings.
• In this case, you will not be able to add this contact by Phone Number through synchronization with the Phone Book of the mobile device.
• You can still add such a contact using his @username.
