Next, you need to add a bot if you have not yet added it. Then click on the "Load Client List" button.

                                          ![](/files/EajDZLjHTDOO8wWTBhVx)                         

Then, in the opened form, either insert the client list into the form, or download the file in csv format

Important, when loading a file, you must specify the correct encoding and separator in the file. The default values are those required to download files saved in Excel. 

Details of the data format are shown on the form, and features specific to each messenger are shown. 

### Addition to the list 

You can add downloadable clients to one or more lists at once, for segmentation.

!!!!!

### Variable transfer 

The first column contains the identifier in the messenger, in the second name of the client. The rest of the columns will be written into client variables. The variable name is taken from the column name. The column names are placed in the first row. Loading of variables will happen automatically.

## Features of Client Download 

Clients become attached to the messenger, meaning that subscribers from one cable bot cannot be uploaded to another. 

### Telegram 

In the telegram platform\_id is a number. 

### Viber 

In viber platform\_id is a string consisting of letters and numbers, ending with two characters equals.

### Whatsapp 

This is the only messenger where clients are not tied to a bot and you can download them simply by a list of numbers. The format of the phone number is free. It will be automatically activated when downloading. 

**Important!!!** If you plan to send messages to the number database, you need to preload the numbers into the client list and then create a mailing list.
