# Chats
## Chat interface
## The blacklist:
For connection chats:
* WhatsApp Business
* WhatsApp Business API
* Telegram Personal
* Telegram Bot, except for group chats\
\
It is possible to add a chat to the blacklist with the "Block" button:
{% hint style="info" %}
❗️The action is displayed only in the chats of the connections that are included in the subscription, and the subscription itself is paid for. However, the "Initial" tariff is not suitable for this action.
❗️ The "Block" action is only available to employees who have the right to "Chats - Add to Emergency".
{% endhint %}
When you click on "Lock", the window with the choice of action closes, and instead a confirmation pop-up window appears.:
If you click the "Block" button, the chat will be added to the blacklist of connections, and a pop-up message will appear indicating that the chat has been successfully added to the blacklist.:
If you click on "Cancel" or on the cross, the confirmation window closes.
Blocked chats in the list are displayed in a lighter color so that there is an understanding of the "chat freeze" and with a lock icon.:
When adding a chat to the blacklist, the message input field in the blocked chat is blocked. The add template and submit buttons are inactive.
## How to unblock a chat:
To unblock the chat, use the "Unblock" button. This action is displayed instead of the “Block” action in already blocked chats.:
{% hint style="warning" %}
**Attention!**\
The "Unblock" action is displayed only in the chats of connections for which a paid subscription has been issued, and the tariff is not "Initial".
**Please note!**\
The "Unblock" action is available only to employees with the right to "Add to emergency" in the "Chats" section.
{% endhint %}
When you click on the "Unlock" button, the action list window closes, the chat is removed from the connection blacklist, and a pop-up message appears. In the chat actions section, the "Unblock" status automatically changes to "Block".
## Counter of unanswered messages
Chats are arranged depending on which chat the last incoming message came to. Opposite the chat, where there are unanswered messages (not to be confused with "not read"), the counter is lit in green, indicating how many incoming messages came from the client.
There are two ways to reset the unanswered message counter:
1 - send a response message to the client
2 - click the "No reply is required" button
## Message statuses
There are 4 types of message statuses:
1. Sent (1 gray check mark)
2\. Delivered (2 gray check marks)
3\. Read (2 green check marks)
4\. Delivery error:
In cases where the message cannot be sent for some reason, the message background will be red with a red exclamation mark icon. When you hover over the red exclamation mark icon, the reason for the error will be displayed.
Errors in RadistWeb chats may be of the following nature:
* “The messenger account was not found” (if there is no account on the contact's phone number)
* “Subscription not paid”
* “There are no paid WABA dialogues”
* "Unknown error. Contact technical support.” (for all other errors). \
In case of such an error, the help of our technical support is already required
* "The limit on outgoing conversations on the subscription plan has been reached"
This error means that the limit of outgoing conversations on your subscription plan has been reached. The [tariff](https://docs.radist.online/docs/our-services/subscription-tariffs) needs to be improved.
## Voice messages
Voice message recording starts by clicking on the "microphone" icon in the chat window:
By clicking on the "cross", you can cancel sending, by clicking on the "checkmark" - send a record of a voice message.
Voice messages are available on “**Standard**” and “**Advanced**” tariffs.
In the “**Initial**” tariff, when sending a voice message, the message “Voice messages are available only on Advanced tariffs” will be displayed
