Last modified:2026-07-17 08:29:24

Returns SMS encoding metadata for a message body: character count, whether it is GSM-7 or Unicode, and the number of segments (parts) it will be split into. No campaign is created - use it to show a live "N parts" hint while composing.

Authentication: Authorization: Bearer <JWT>.

Body fields

message (string, required) - the message text to analyze.

convertTo7Bit (boolean, default false) - when true, convert/transliterate the text to GSM 7-bit before counting (usually fewer parts, but may replace non-GSM characters).
