Welcome to the Talkus Developer Documentation.

Talkus is very customizable and open. You’ll find on this page all the API and integration you can do with Talkus.



An agent is an user of your company that is inside your Slack team and handle support requests.


A visitor is one of your users that is not in Slack and contact you by a Talkus channel (email, live chat, sms, twitter…).

Visitor Channel

A Visitor Channel is a Slack channel where you interact with a specific visitor. It’s not the #talkus-support. Visitor Channel names always start with #z-.



curl -X POST \
  --user '1234562a44147d1b3b3bad556784beae:' \

When you call Talkus endpoints, you need to add the Authorization header using the Basic authentication type. The login will be the API Key you’ll find in the integration page and the password will be empty.

Send Message

Send a message from a new visitor (the visitorId will be created):

curl -X POST \
  --user '1234562a44147d1b3b3bad556784beae:' \
  -H 'Content-Type: application/json' \
  -d '{ "text": "hello there!" }' \

The above command returns JSON structured like this:

  "ok": "true",
  "visitorId": "5rTdrc986vWm12"

Send a message from an existing visitor:

curl -X POST \
  --user '1234562a44147d1b3b3bad556784beae:' \
  -H 'Content-Type: application/json' \
  -d '{ "visitorId": "5rTdrc986vWm12", "text": "I need your help!" }' \

The above command returns JSON structured like this:

  "ok": "true",
  "visitorId": "5rTdrc986vWm12"

If there’s an error, it’ll be like this:

  "ok": "false",
  "error": "No text"


Post a new visitor message to an exiting visitor (if you set the visitorId) or to a new visitor (in this case, the result will contains the visitorId).

This entrypoint is useful if you want to add a new channel (another SMS provider for example). When your external provider sends you a message coming from a visitor’s phone for example, call this entrypoint to create or update a ticket into Talkus (and so in Slack) with the visitor’s message.

If it’s a new visitor (you don’t have visitorId), call the entrypoint without visitorId so we’ll create a new one for you and return it. Then you store in your database the visitorId and phone number (or any other id you want) so next time this visitor sends you a message, you can provide the visitorId and Talkus will add the message to this existing visitor.


Parameter Options Description
text mandatory The visitor’s message.
visitorId optional The id of the visitor. If not set, it’ll create a new visitor and returns the new id.
type optional The name or emoji (using long emoji format like :poop:) that will be displayed on the ticket.
identity optional A JSON object that containing information of the visitor. More information…


On Command page, you can create dot commands. A dot command always starts with a dot (.) and are executed only when typed inside a visitor channel (where you answer to your visitor). When you type a dot command, the visitor doesn’t see it but he’ll see the result of the command, except if the result starts with a double dot (..), in this case, the result will be only be visible to the agent.

Post a message

Most basic form of a dot command, when the agent execute the command, it displays the message entered in Value.

Useful to create canned responses.

Execute a Server command

Call a webhook on your server when the dot command is executed by the agent. It’s a POST requests on your server containing a JSON with all the information you need, agent who executed the command, on which visitor, the discussion.

You can reply to this POST either with:

"I am a test message"
    "text": "I am a test message",
    "attachments": "[{ \"text\": \"And here's an attachment!\" }]"

For example, you can create a command .ban that will call your server and your server will ban the visitor on your product.

Another example, for an e-commerce website, can be .status that will find the status of the latest visitor order and returns it to the agent and / or visitor.

Execute a Client command

Execute the javascript code you entered in Value input in the browser of the visitor.

window.location.href = '';

If you use this code in a command called .google, when executed, it’ll redirect the visitor to google homepage.

Alias to another command

Alias a command with another one. For example by default, you have alias of end with e so instead of typing .end to close a discussion, you can just type .e.

On the Integration page, you’ll have a webhook input.

Fill this input with an entry point on your server.

We’ll HTTP POST it with a JSON in the body containing information about the visitor, the agent and the whole conversation.

We call this webhook in these cases:

Name Description
start when a new conversation is starting.
open when a conversation is opened (an agent entered the channel).
end when a conversation is closed (.end called by the agent).
email when the visitor entered its email.
messageVisitor when a visitor sent a new message (message contains the visitor’s message).
messageAgent when an agent sent a new message (message contains the agent’s message).

Javascript functions


On the client side of the live chat plugin, you can add more javascript code after the Talkus snippet to interact with the plugin.


Anonymous initialization:

talkus('init', 'yourappid');

This function must be the first one to call to initialize Talkus.

You can call it multiple times if you want to update the identity of the visitor. Useful for Single Page Application (SPA).

Initialization with identification of the visitor:

talkus('init', 'yourappid', {
  id: '1234'
  name: 'John Doe',
  email: '',

If your visitor is logged, you often want to provide extra info to Talkus so your agents will be able to know who the visitor is.

To do that, you have to add a third parameter to the talkus('init') function that contains a javascript object.

This object can contains any keys/values you want but the following keys are used by Talkus to enhance the visitor:

Key Value  Description
id optional, must be unique An unique string that is linked to this visitor. We’ll use it to identify the visitor in our database. So even if the visitor is on another computer or in incognito mode, you’ll have all the information about him. The id must be uniq per visitor.
name optional, String Name of the visitor. We’ll use it to name the visitor Slack channel.
email optional, ‘’ Email address of the visitor. If you provide the email, Talkus will not ask the visitor for his email. If Talkus has the email but not the name, it’ll use the email to name the Slack channel. An email will be sent if the visitor leave a live chat.
phone optional, ’+33123456789’ Phone number of the visitor. Talkus will use it to send SMS.
picture optional, '’ The url to the picture of the visitor avatar. It’ll be displayed in your Slack channel.
tag optional, 'pro’ You can programmatically tag ticket in the html code. Tagging is useful to separate different type of visitors or subdomains. For example, you can create a pro tag for pro visitors that needs instant support. All tickets will go to #zz-pro Slack channel instead of the default #talkus-support where you can set Slack notification to a higher level to never miss them.

You can add any other fields you want, they’ll be displayed in Slack visitor information. It can be useful for example to display if the visitor uses a free or paying plan, display a link to your backoffice for this visitor, …

External channels

Talkus has channels like live chat, email, sms, phone, twitter, facebook but you can add your own channel.

To do that, you need to implement 2 things:
