Returns delivery counts, read engagement and latency grouped by the recipient's destination country. Rows use send-time attribution, rank by accepted volume, and are capped by limit (default 50, maximum 200). A recent period under-reports delivered while delivery reports are still arriving. The maximum window is 365 days; a longer range returns 422.

A country row covers messages addressed to a single recipient. A recipient whose country cannot be resolved (a number shaped like a phone number that belongs to no country, or a non-geographic range such as freephone) is counted under ZZ rather than dropped, matching the SMS country breakdown. Group sends are omitted entirely: one spans up to eight recipients in as many countries, so no single destination country describes it. These rows therefore sum to the summary less that group volume. A window reaching before this breakdown shipped falls short by more than that: history was seeded only where the recipient's country could be recovered from stored data, so a phone-addressed send accepted before the cutover has no accepted leg here. Two cases follow, and they read differently. Acceptance days more than 14 days before the cutover are a plain shortfall and never change. In the 14 days immediately before it, a delivered, read or failed callback arriving after the cutover does carry a country and is attributed to its original acceptance day, so a row there can report deliveries with accepted at zero. Its delivery_rate and failure_rate are then null for want of a denominator while read_rate still computes and looks healthy. The 14 days are the status recording window, after which a callback is dropped. All of this is confined to pre-cutover acceptance days and gone once the requested window starts after the cutover date.

Latency reports the same three families as the summary: processing, delivery and total. The delivery family depends on a best-effort handoff timestamp that a fast delivery callback can beat, so it can be absent for a country whose other two families are present.

A breakdown is already a single-dimension view and takes no dimension filter; to restrict statistics to a single template, category, phone number or tag, use the summary, daily or hourly statistics instead.

Query Parameters

fromstring

Inclusive start of the window, a calendar day (YYYY-MM-DD). Interpreted in timezone, or UTC when omitted. Must not be after to. Max window 365 days. Defaults to 30 days before to when omitted.

tostring

Inclusive end of the window, a calendar day (YYYY-MM-DD). Interpreted in timezone, or UTC when omitted. Max window 365 days. Defaults to today in that timezone when omitted.

timezonestring

IANA timezone identifier used to group statistics, for example Asia/Kathmandu. The default is UTC. Day and hour boundaries, including the default window when from and to are omitted, follow this timezone. When this parameter is set, pass from and to as calendar days or Z instants instead of timestamps with explicit UTC offsets.

limitinteger

Maximum number of country rows to return, ranked by accepted volume descending.

Response Payload

period
object
required

The window the response covers (echoed back), plus data_as_of.

Show child attributes
data
array of object
required

Country rows ranked by accepted volume descending. Empty when no eligible activity occurred in the period; rows sum to the summary less group-send volume, and less any pre-cutover phone-addressed sends still inside the window.

Show child attributes
data.country
string
required

The destination country this row aggregates, as an ISO 3166-1 alpha-2 code. ZZ collects recipients whose country could not be resolved.

data.delivery
object
required

WhatsApp lifecycle counts and rates for the requested period, attributed by send time, so a later delivery stays attributed to the period in which its message was accepted, and a recent period under-reports delivered while delivery reports are still arriving. The sibling engagement block reports read counts and rates. Rates are null when their denominator is zero. Very large counts are close estimates rather than exact tallies.

Show child attributes
data.engagement
object
required

WhatsApp engagement counts and the derived read rate for the scope of the containing row (the whole requested period or a breakdown dimension). The read field is the number of distinct messages confirmed read by the recipient. Send time determines attribution; the instant the read receipt arrived does not. A read is counted in the period its message was accepted in, alongside that message's own delivery when one arrived. The read rate divides reads by messages delivered in the same scope and is null when its denominator is zero. Very large counts are close estimates rather than exact tallies.

Show child attributes
data.latency
object
required

Latency percentiles in milliseconds for the requested scope:

  • processing: From acceptance to WhatsApp handoff.
  • delivery: From WhatsApp handoff to delivery confirmation.
  • total: From acceptance to delivery confirmation.

Each family is omitted when no qualifying message contributes a measurement. Individual percentiles can also be null. delivery is measured on a best-effort basis, so it can be absent for a scope whose processing and total are present.

Show child attributes
data.latency.processing
object

Approximate p50, p95, and p99 latency percentiles in milliseconds for one latency family. All three are null when no qualifying event contributed a measurement.

Show child attributes
data.latency.delivery
object

Approximate p50, p95, and p99 latency percentiles in milliseconds for one latency family. All three are null when no qualifying event contributed a measurement.

Show child attributes
data.latency.total
object

Approximate p50, p95, and p99 latency percentiles in milliseconds for one latency family. All three are null when no qualifying event contributed a measurement.

Show child attributes
data.latency.total.p50_ms
nullable integer
required

Median (50th percentile) latency in milliseconds. Null when no qualifying event contributed a measurement.

data.latency.total.p95_ms
nullable integer
required

95th percentile latency in milliseconds. Null when no qualifying event contributed a measurement.

data.latency.total.p99_ms
nullable integer
required

99th percentile latency in milliseconds. Null when no qualifying event contributed a measurement.

total
integer
required

Total distinct countries with activity in the period, regardless of limit.
