Hourly received-message counts

GET
/v1/sms/stats/inbound/hourly
const stats = await bird.sms.stats.inbound.hourly({
  from: "2026-05-30T00:00:00Z",
  to: "2026-05-31T00:00:00Z",
});
for (const point of stats.data ?? []) {
  console.log(point.bucket, point.received);
}
Returns the number of messages your numbers received, one row per hour.
Rows are bucketed by the time the carrier received the message. Hours with no messages are still included, with a count of zero, so a chart has no gaps.
A row carries a count and nothing else. A received message has one state, so there is no lifecycle to break down and no delivery latency to report; the send statistics endpoints cover those for messages you send.
The maximum window is 720 hours; a longer range returns 422. Set timezone to bucket rows by your local hour instead of UTC.
Abfrageparameter
from
string
Start of the window (inclusive), an RFC 3339 instant truncated to the hour. Defaults to 7 days (168 hours) before to when omitted.
to
string
End of the window (inclusive), an RFC 3339 instant truncated to the hour. Defaults to the current hour when omitted. Window may not exceed 720 hours. A numeric UTC offset (for example +05:45) is rejected when timezone is set; pass a calendar day or a Z instant instead.
timezone
string
IANA timezone identifier (for example Asia/Kathmandu) to report in; defaults to UTC. Day and hour boundaries and the default window when from and to are omitted both follow it, so a calendar-day from or to names a local day. A from or to carrying its own UTC offset is rejected while this is set: pass a calendar day or a Z instant.
Antwort-Payload
period
object
erforderlich
The window and bucket grain the response covers, echoed from the request, plus the freshness boundary the data is current to.
Untergeordnete Attribute anzeigen
period.from
string
erforderlich
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.
period.to
string
erforderlich
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.
period.grain
string
erforderlich
The bucket grain of the series, either day or hour.
Possible values: day, hour
period.data_as_of
nullable string
The instant the statistics in this response are current to: events recorded up to roughly this time are reflected, while more recent events may not be yet. Statistics are served from a rolling aggregation that refreshes every few seconds, so a response is near-real-time but not live; use this field to label data freshness rather than assuming the numbers are to-the-second. Null when the freshness boundary is not being reported.
data
array of object
erforderlich
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.
Untergeordnete Attribute anzeigen
data.bucket
string
erforderlich
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.
data.received
integer
erforderlich
Distinct messages received in this bucket, counted by the time the carrier received them.
