A Conversation is a distinct omni-channel messaging thread (i.e. a place where users from multiple channels can exchange messages), in which Participants from any channel Conversations supports (e.g. SDK, SMS, WhatsApp) can communicate with each other.
You can create and manage new Conversations using either the Conversations REST API or the client-side Conversations SDK (what we’re covering here). Let’s start to dive in!
You’ll create a new Conversation using the Conversation creation (JS, iOS) or Conversation Builder methods on your new initialized Client object. Optionally, you can pass in the following parameters:
After creating the Conversation, you’ll need to join it to participate. Joining will create a Participant object in the Conversation that is associated with your User. This also subscribes you to events from the Conversation.
If you’d like to stop receiving events from this Conversation and remove your Participant, you can call the appropriate method to leave the Conversation.
There are two types of Participants:
- Chat (SDK-based) Participants, or
- Non-chat (e.g. SMS, WhatsApp) Participant
SDK-based (chat) Participant objects have a many-to-1 relationship with User objects. In other words, a User represents a human using the SDK and has a unique Participant object in each Conversation they are participating in. Non-chat Participants (i.e. SMS, WhatsApp, etc.) are not linked by a User object even when they are the same human participating in multiple Conversations.
Users are uniquely identified by the
identity property in the Access Token they initialized their Client with. You can create a Chat Participant belonging to that User in the Conversation by specifying their User’s identity in the corresponding creation method.
To add a non-chat Participant to the Conversation, you’ll have to pass the proxyAddress and address parameters to the specific creation method on the Conversation object. Make sure to replace the proxyAddress parameter with a Twilio address (i.e. phone number, WhatsApp sender) and the address parameter with the real-world phone number or address that the Participant is using.
You can get the list of all Participants within the Conversation by invoking the corresponding method on the Conversation object.
To list the latest messages of a Conversation, call the appropriate method on the Conversation object and optionally specify the index of a specific Message to start from.
There are a few options, you can review the auto-generated documentation to familiarize yourself with the parameters you can use to modify this behavior.
Because all Conversations are private, listing Conversations will only return Conversations that you are participating in. Call the appropriate method to retrieve them.
