MTS Link data API: sessions, roster and transcripts

VEBINAR TEKHNOLOGII, OOO · Communication

MTS Link is the Android client from VEBINAR TEKHNOLOGII, OOO for MTS Link — the webinar.ru meetings and webinar platform after its rebrand under Russian telecom MTS. Users sign in with email and password or company SSO, then work from a calendar of event sessions: join as a guest with a nickname, register for a paid event, start or stop a live room, and open a recording with a transcript. Hosts see lectors, translators and access gates (password, registration or moderation); participants sit on a roster with role and payment status. The app serves Russian enterprises, universities and training teams that already buy MTS Link webinars, sitting next to Zoom Workplace, Microsoft Teams and TrueConf in the same meetings slot.

Signed-in cabinet cards mint a sessionId cookie plus an authentication pair of accessToken and refreshToken. The user record carries id, type, name, secondName, nickname, email, phone, organization, position and organizationId. Feature flags add isMeeting, hasPersonalCabinet and showMobileAppMigrationBanner; SSO choosers list name and redirectUrl.

Timetable payloads are ISO date strings. Schedule rows expose cost, isEventRegAllowed, startsAt, estimatedAt, endsAt, duration, isEndless, timezone, eventLink, eventId and nested eventSessions. A session detail adds accessSettings (isPasswordRequired, isRegistrationRequired, isModerationRequired), lectors, languages and hasTranslators.

Guest join returns guestLoginId and isAccepted. Registration posts additionalFields and acceptedAgreementIds, then mints a new sessionId. The roster lists role, isTranslator, languageCode, registerStatus and paymentStatus. Recording status reports isRecording, isControlAllowed and sessionStatus. Transcript pages carry transcriptName, line dateTime/text/userId and nextPageCursor, with a nested summary. Paid checkout returns paymentUrl for a participationId.

LMS calendars can hydrate session dates, attendance desks can reconcile the roster against paymentStatus, and compliance archives can store transcripts next to recording flags — and openData Studio turns that webinar ledger into callable open data.

Where teams use this data

LMS calendar hydration
Training desks pull timetable ISO date strings and schedule rows (startsAt, eventLink, cost) so a campus LMS lists the same webinars the mobile calendar paints.
Attendance and payment desk
Ops consoles read the session roster (role, registerStatus, paymentStatus) and paid-ticket checkout (paymentUrl) to reconcile who is admitted versus who still owes.
Recording and transcript archive
Compliance bots poll capture status (isRecording, sessionStatus) then page transcript lines (dateTime, text, userId) and the nested summary.
Guest-join kiosk
Lobby tablets send walk-in nickname join (nickname, isAccepted) or event enrollment so walk-in attendees mint a session without a cabinet password.

Frequently asked questions

How does MTS Link authenticate mobile API calls?

Cabinet email-password sign-in accepts email, password and deviceId and returns sessionId plus authentication.accessToken and authentication.refreshToken. Later calls send Cookie: sessionId=. A refresh call exchanges refreshToken for a new JWT pair. SSO choosers list name and redirectUrl before that handoff.

Which fields expose the webinar calendar?

Marked-day payloads are ISO date strings. Schedule rows carry startsAt, cost, eventLink and nested eventSessions. A session detail hydrates accessSettings, lectors and eventLink for the room-join screen.

How do guests and paid attendees join?

Walk-in join sends nickname and device metadata and returns guestLoginId and isAccepted. Event enrollment registers email, name and secondName. The roster lists role, registerStatus and paymentStatus. Checkout returns paymentUrl for type=card.

Where are recordings and transcripts?

Capture status returns isRecording, isControlAllowed and sessionStatus. Transcript pages return transcriptName and items (dateTime, text, userId, nickname) plus nextPageCursor. A digest call returns data.summary.
