SMS statistics and reports through the API: totals by status, credits spent and days

The short answer: GET /v1/sms/stats gives you, for a period, how many messages and parts went out, the credits spent, totals by status and one line for each day with messages. Without dates it covers the last 30 days; the longest period is 366. That is enough for a monthly report without adding up message by message.

The request and the answer

curl "https://api.mozout.co.mz/v1/sms/stats?from=2026-10-01&to=2026-10-31" \
-H "Authorization: Bearer prod_..."

Field	What it tells you
from, to	The period counted, YYYY-MM-DD to YYYY-MM-DD.
messages	How many messages there were in the period.
parts	How many parts they added up to.
credits_spent	Credits spent. Failed, cancelled and simulated messages do not count, nor do scheduled ones not yet charged.
by_status	Totals by status: scheduled, queued, sending, sent, simulated, failed, cancelled.
by_day	One line per day with messages: date, messages, sent, failed and credits.

What the numbers tell you

Sign	What it means	What to do
Far more parts than messages	Long texts, or accents that switch them to Unicode.	Shorten the texts: see writing transactional SMS.
Failures going up	Wrong numbers in your database, or a send that went wrong.	Check the failure reasons and clean the numbers: cleaning the numbers.
A day at twice the usual volume	A repeated notice, or a campaign.	Make sure your system is not sending the same event twice.
Credits spent rising month after month	The business grew, or there are too many notices.	Review your purchase tiers: credits and price tiers.

An automatic monthly report

1	Create a read-only key, with the sms:read permission and nothing else.

2	On the first day of each month, a scheduled job calls GET /v1/sms/stats with the previous month in from and to.

3	It adds GET /v1/sms/balance, which gives the balance in credits, the daily limit, what has gone out today and the scheduled credits not yet charged.

4	It e-mails the summary to whoever decides on credit purchases.
