Each Participant in a Conversation represents one real (probably human) participant in a Conversation.
Creating a Participant joins them with the conversation, and the connected person will receive all subsequent messages.
Deleting a participant removes them from the conversation. They will receive no new messages after that point, but their previous messages will remain in the conversation.
All URLs in the reference documentation use the following base URL:
https://conversations.twilio.com/v1
Using the REST API, you can interact with Conversation Participant resources in the default Conversation Service instance via a "shortened" URL that does not include the Conversation Service instance SID ("ISXXX..."). If you are only using one Conversation Service (the default), you do not need to include the Conversation Service SID in your URL, e.g.
1GET /v1/Conversations/CHxx/Participants2
For Conversations applications that build on more than one Conversation Service instance, you will need to specify the Conversation Service SID in the REST API call:
GET /v1/Services/ISxx/Conversations/CHxx/Participants
The unique ID of the Account responsible for this participant.
^AC[0-9a-fA-F]{32}$Min length: 34Max length: 34The unique ID of the Conversation for this participant.
^CH[0-9a-fA-F]{32}$Min length: 34Max length: 34A 34 character string that uniquely identifies this resource.
^MB[0-9a-fA-F]{32}$Min length: 34Max length: 34A unique string identifier for the conversation participant as Conversation User. This parameter is non-null if (and only if) the participant is using the Conversations SDK to communicate. Limited to 256 characters.
An optional string metadata field you can use to store any data you wish. The string value must contain structurally valid JSON if specified. Note that if the attributes are not set "{}" will be returned.
Information about how this participant exchanges messages with the conversation. A JSON parameter consisting of type and address fields of the participant.
The SID of a conversation-level Role to assign to the participant.
^RL[0-9a-fA-F]{32}$Min length: 34Max length: 34Index of last “read” message in the Conversation for the Participant.
Timestamp of last “read” message in the Conversation for the Participant.
POST https://conversations.twilio.com/v1/Conversations/{ConversationSid}/ParticipantsAdding a new participant to an ongoing conversation immediately allows them to see all subsequent communications. The same person (i.e., a single personal phone number) can be part of any number of conversations concurrently, as long as the address they are in contact with (the ProxyAddress) is unique.
To create a Conversation Participant by SMS, you must enter:
messagingbinding.addressmessagingbinding.proxyaddress.To create a Conversation Participant by Chat, you must enter the Chat User Identity as the identity parameter.
We recommend following the standard URI specification and avoid the following reserved characters ! * ' ( ) ; : @ & = + $ , / ? % # [ ] for values such as identity and friendly name.
The X-Twilio-Webhook-Enabled HTTP request header
truefalseThe unique ID of the Conversation for this participant.
application/x-www-form-urlencodedA unique string identifier for the conversation participant as Conversation User. This parameter is non-null if (and only if) the participant is using the Conversations SDK to communicate. Limited to 256 characters.
The address of the participant's device, e.g. a phone or WhatsApp number. Together with the Proxy address, this determines a participant uniquely. This field (with proxy_address) is only null when the participant is interacting from an SDK endpoint (see the 'identity' field).
The address of the Twilio phone number (or WhatsApp number) that the participant is in contact with. This field, together with participant address, is only null when the participant is interacting from an SDK endpoint (see the 'identity' field).
An optional string metadata field you can use to store any data you wish. The string value must contain structurally valid JSON if specified. Note that if the attributes are not set "{}" will be returned.
The address of the Twilio phone number that is used in Group MMS. Communication mask for the Conversation participant with Identity.
