# Get daily inbound SMS statistics

`GET /v1/sms/stats/inbound/daily`

## Request

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

Returns the number of messages your numbers received, one row per calendar day. Rows use the time the carrier received each message, and days with no messages contain a zero count.

Each row contains only a count because a received message has one state. Use the outbound statistics endpoints for lifecycle and delivery-latency data about messages you send.

The maximum window is 365 days; a longer range returns 422. Set `timezone` to bucket rows by your local calendar day instead of UTC.

## Query parameters

- `from` string, date
- `to` string, date
- `timezone` string

## Headers

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

## Response `200`

Received-message counts per day for the requested period.

- SMSInboundStatsResponse: Received-message time series. `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` SMSInboundStatsPoint[], required: One row per bucket (day or hour, per the grain) in the period, in chronological order. Buckets with no activity are included with a count of zero, so the series charts continuously without client-side gap handling.
    - `bucket` string, required: Start of the bucket this row covers, as a calendar day (YYYY-MM-DD) for the daily series or an hour boundary (RFC 3339) for the hourly one.
    - `received` integer, required: Distinct messages received in this bucket, counted by the time the carrier received them.

## 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.
