# Get daily outbound SMS statistics

`GET /v1/sms/stats/daily`

## Request

- Base URL: `https://us1.platform.bird.com`
- URL: `https://us1.platform.bird.com/v1/sms/stats/daily`
- Auth: one of:
  - HTTP bearer
  - API key in cookie `bird_session`

Returns one row of SMS lifecycle counts per calendar day. Rows use send-time attribution, so a delivery confirmation is counted on the day when its message was accepted. Recent rows can under-report `delivered` while delivery reports arrive. Days without activity contain zero counts.

Rates and latency are whole-window aggregates available from the summary endpoint. Use the message detail endpoints for individual message status.

A request may span up to 365 days; a longer window returns `422`. Set `timezone` for local calendar days instead of UTC.

## Query parameters

- `from` string, date
- `to` string, date
- `timezone` string
- `originator` string
- `country` string
- `category` string
- `carrier` string

## Headers

- `X-Workspace-Id` string
- `X-Organization-Id` string

## Response `200`

Daily aggregate stats for the requested period.

- SMSStatsResponse: Time-series stats payload. `period` echoes the range and bucket grain the server computed against; `data` is one row per bucket in chronological order.
  - `period` SMSStatsSeriesPeriod, required: The window and bucket grain the response covers, echoed from the request, plus the freshness boundary the data is current to.
    - `from` string, required: Inclusive start of the window. A calendar day (YYYY-MM-DD) on the day grain, an RFC 3339 instant rounded to the hour on the hour grain.
    - `to` string, required: Inclusive end of the window. A calendar day (YYYY-MM-DD) on the day grain, an RFC 3339 instant rounded to the hour on the hour grain.
    - `grain` 'day' | 'hour', required: The bucket grain of the series, either `day` or `hour`.
    - `data_as_of` string, date-time, nullable: Latest time reflected in the statistics. More recent events might not be included yet. Null when the freshness boundary is unavailable.
  - `data` SMSStatsPoint[], required: One row per day or hour in chronological order. Buckets with no activity contain zero counts.
    - `bucket` string, required: The day (YYYY-MM-DD) or hour (RFC 3339, on the hour) this point covers, matching the period's grain.
    - `delivery` SMSDeliveryCounts, required: SMS lifecycle counts for a time bucket. Counts use the message send time, so a message accepted on Monday and delivered on Tuesday counts in Monday's bucket. Rates are available only for whole periods and breakdowns.
      - `accepted` integer, required: Distinct messages accepted for sending after admission checks.
      - `sent` integer, required: Distinct messages handed off to the carrier for delivery.
      - `delivered` integer, required: Distinct messages the carrier confirmed as delivered to the handset.
      - `undelivered` integer, required: Distinct messages the carrier reported as not delivered.
      - `failed` integer, required: Distinct messages that failed during sending.
      - `rejected` integer, required: Distinct messages rejected before any send attempt, for example by sending policy or a message-generation failure.
      - `expired` integer, required: Distinct messages that could not be delivered within their validity window and expired.

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Insufficient permissions
- `404`: Resource not found
- `422`: The request has invalid field values, violates a business rule, or carries a query parameter the endpoint does not declare. Field validation errors use `type: validation_error` and include the affected fields in `details`. Business-rule errors identify the failed rule in `type`.
- `429`: Rate limit exceeded
- `500`: Internal server error
- `503`: The service is temporarily unavailable. If `Retry-After` is present, wait for that delay before retrying; otherwise, retry with exponential backoff. Reuse the same idempotency key and request when retrying a mutation.
