Send messages to API channel

To send messages to API channel, you need have a basic understanding of the models and nomenclature used in Chatwoot. Let us try to understand these first.

  1. Channel: Channel defines the type of the source of conversations. Eg: Facebook, Twitter, API etc.

  2. Inbox: You can create multiple sources of conversations which is of the same channel type. For eg: You can have more than one Facebook page connected to a Chatwoot account. Each page is called as the inbox in Chatwoot.

  3. Conversation: A Conversation is a collection of messages.

  4. Contact: Each conversation has a real life person associated with it, this person is called a contact.

  5. Contact Inboxes: This is the session for each contact on a inbox. A contact can have multiple sessions and multiple conversations in the same inbox.

How to send a message in an API Channel?#

To send a message in an API channel, you have to create a contact, then create a conversation and then send a message.

APIs require api_access_token in the request header. You can get this token by visiting your Profile settings > Access Token

1. Create a contact#

API documentation: (https://www.chatwoot.com/developers/api/#operation/contactCreate)

Pass the inbox id of the API channel along with other params specified. This would create a session for you automatically. A sample response would look like the one below.

{  "email": "string",  "name": "string",  "phone_number": "string",  "thumbnail": "string",  "additional_attributes": {},  "contact_inboxes": [    {      "source_id": "string",      "inbox": {        "id": 0,        "name": "string",        "website_url": "string",        "channel_type": "string",        "avatar_url": "string",        "widget_color": "string",        "website_token": "string",        "enable_auto_assignment": true,        "web_widget_script": "string",        "welcome_title": "string",        "welcome_tagline": "string",        "greeting_enabled": true,        "greeting_message": "string"      }    }  ],  "id": 0,  "availability_status": "string"}

As you can see in the payload, you will be able to see the contact_inboxes and each contact_inbox will have a source_id. Source Id can be seen as the session identifier. You will use this source_id to create a new conversation as defined below.

2. Create a conversation#

API documentation: (https://www.chatwoot.com/developers/api/#operation/newConversation)

Use the source_id received in the previous API call.

You will receive a conversation id which can be used to create a message.

{  "id": 0}

3. Create a new message#

API documentation: (https://www.chatwoot.com/developers/api/develop/#operation/create-a-new-message-in-a-conversation)

There are 2 types of messages.

  1. Incoming: Messages sent by the end user is classified as an incoming message.

  2. Outgoing: Messages sent by the agent is classified as an outgoing message.

If you call the API with the correct content, you will receive a payload similar to the one below.

{    "id": 0,    "content": "This is a incoming message from API Channel",    "inbox_id": 0,    "conversation_id": 0,    "message_type": 0,    "content_type": null,    "content_attributes": {},    "created_at": 0,    "private": false,    "sender": {        "id": 0,        "name": "Pranav",        "type": "contact"    }}

If everything is sucessful you will see the conversation on the dashboard as follows.
