## Properties

| Field | Description |
|-------|-------------|
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `account_sid` | The SID of the [Account](https://www.twilio.com/docs/iam/api/account) that created the Service resource. |
| `callback_url` | The URL we call when the interaction status changes.. Format: uri |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `chat_instance_sid` | The SID of the Chat Service Instance managed by Proxy Service. The Chat Service enables Proxy to forward SMS and channel messages to this chat instance. This is a one-to-one relationship. |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `date_created` | The [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) date and time in GMT when the resource was created.. Format: date-time |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `date_updated` | The [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) date and time in GMT when the resource was last updated.. Format: date-time |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `default_ttl` | The default `ttl` value for Sessions created in the Service. The TTL (time to live) is measured in seconds after the Session's last create or last Interaction. The default value of `0` indicates an unlimited Session length. You can override a Session's default TTL value by setting its `ttl` value. |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `geo_match_level` | Where a proxy number must be located relative to the participant identifier. Can be: `country`, `area-code`, or `extended-area-code`. The default value is `country` and more specific areas than `country` are only available in North America.. Values: `area-code`, `overlay`, `radius`, `country` |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `intercept_callback_url` | The URL we call on each interaction. If we receive a 403 status, we block the interaction; otherwise the interaction continues.. Format: uri |
| `links` | The URLs of resources related to the Service.. Format: uri-map |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `number_selection_behavior` | The preference for Proxy Number selection in the Service instance. Can be: `prefer-sticky` or `avoid-sticky`. `prefer-sticky` means that we will try and select the same Proxy Number for a given participant if they have previous [Sessions](https://www.twilio.com/docs/proxy/api/session), but we will not fail if that Proxy Number cannot be used.  `avoid-sticky` means that we will try to use different Proxy Numbers as long as that is possible within a given pool rather than try and use a previously assigned number.. Values: `avoid-sticky`, `prefer-sticky` |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `out_of_session_callback_url` | The URL we call when an inbound call or SMS action occurs on a closed or non-existent Session. If your server (or a Twilio [function](https://www.twilio.com/en-us/serverless/functions)) responds with valid [TwiML](https://www.twilio.com/docs/voice/twiml), we will process it. This means it is possible, for example, to play a message for a call, send an automated text message response, or redirect a call to another Phone Number. See [Out-of-Session Callback Response Guide](https://www.twilio.com/docs/proxy/out-session-callback-response-guide) for more information.. Format: uri |
| `sid` | The unique string that we created to identify the Service resource. |
# credo:disable-for-next-line Credo.Check.Readability.MaxLineLength
| `unique_name` | An application-defined string that uniquely identifies the resource. This value must be 191 characters or fewer in length and be unique. Supports UTF-8 characters. **This value should not have PII.** |
| `url` | The absolute URL of the Service resource.. Format: uri |

# `t`
