# Service-Scoped Delivery Receipt Resource

**Service-Scoped Delivery Receipts** in Conversations provide visibility into the status of Service-Scoped [Conversation Messages](/docs/conversations/api/service-conversation-message-resource) sent across different Conversations within a **non-default** Conversation Service.

Using Service-Scoped Delivery Receipts, you can verify that Messages have been sent, delivered, or even read (for OTT) by Conversations Participants within a **non-default, service-scoped** Conversation Service.

## API Base URL

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

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

```

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/Messages

```
