# Conversation Participant Resource

Each **Participant** in a Conversation represents one real (probably human) participant in a [Conversation](/docs/conversations/api/conversation-resource).

[Creating a Participant](#add-a-conversation-participant-sms) joins them with the conversation, and the connected person will receive all subsequent [messages](/docs/conversations/api/conversation-message-resource).

[Deleting a participant](#delete-a-conversationparticipant-resource) removes them from the conversation. They will receive no new messages after that point, but their previous messages will remain in the conversation.

## API Base URL

All URLs in the reference documentation use the following base URL:

```bash
https://conversations.twilio.com/v1
```

### Using the shortened base URL

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.

```bash
GET /v1/Conversations/CHxx/Participants

```

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:

```bash
GET /v1/Services/ISxx/Conversations/CHxx/Participants
```

## Add a Conversation Participant (SMS)

`POST https://conversations.twilio.com/v1/Conversations/{ConversationSid}/Participants`

Adding 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:

1. Their phone number as the `messagingbinding.address`
2. Your Twilio number as the `messagingbinding.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.*
