Integrating secure video conferencing into your application can significantly enhance user engagement and collaboration. A video conferencing API lets developers create, schedule, and manage video meetings from their own systems without building media infrastructure. This guide covers what these APIs do, how a real integration works against documented endpoints, the security controls you should require, and the limits that catch teams out in production.
Quick Answer
A video conferencing API is a set of HTTP endpoints that let your application create, schedule, join, and end video meetings programmatically. You do not build signalling, media routing, or recording infrastructure. Most return a join URL that your users open. A working integration usually takes days rather than weeks, because the provider handles all media infrastructure.

What is a Video Conferencing API?
A video conferencing API is a set of HTTP endpoints that let your application create, join, schedule, and end video meetings programmatically. It removes the need to build media servers, network traversal for users behind firewalls, or recording infrastructure.
Two Categories, One Name
Two different products share this label, and the distinction decides your architecture before you write any code.
- A meeting-lifecycle API manages the session and returns a join URL. Your users enter the vendor’s meeting interface. Integration takes days. Zoom’s Meeting API, Microsoft Graph, and Convay work this way.
- A media SDK hands you raw audio and video streams and you build the call interface yourself. Integration takes weeks or months, and you own that interface permanently. Twilio Video, Agora, and Daily sit here.
Pick the first if meetings support a workflow you already own, such as a booking, a class, or a consultation. Pick the second if video is the experience your customers pay for. Our guide to build versus buy for video call SDKs works through the trade in detail.
Architecture
A meeting-lifecycle integration has three moving parts.
Your Backend --> Video API --> returns meetingId + join URLs
|
v
Your Users --> open join URL --> vendor meeting interfaceYour backend authenticates and creates meetings. The API returns identifiers and join URLs. Your users open those links. Nothing sensitive touches the browser, which is the property that makes this pattern safe by default.
Key Features and Benefits
Sort features into two piles. The first pile touches your data model or compliance posture and is painful to retrofit. The second is cosmetic and every serious vendor either has it or can add it.
Structural, and worth evaluating:
- Access control: per-user join links rather than one shared URL, password protection, and an option to require authenticated users.
- Role separation: host and participant privileges enforced at the link level, not just hidden in the interface.
- Recording governance: a documented storage location, retention period, and deletion path.
- Scale ceiling: the maximum participant count, and whether exceeding it needs a different code path.
- Deployment options: whether self-hosting exists at all, which matters enormously in regulated sectors.
Cosmetic, and not a deciding factor: virtual backgrounds, emoji reactions, and layout presets.
Implementation: A Real Integration
The examples below use Convay’s Meeting API, documented at version 6.2, so the endpoints and payloads are real rather than placeholders. The base URL is https://convay.com and meetings open at https://app.convay.com.
Step 1: Authenticate
Exchange credentials for a token pair. This happens on your server, never in browser code.
POST /services/vcmeetingsettings/user/authenticate
Content-Type: application/json
{ "username": "client_user", "password": "secure_password" }A successful response returns an accessToken and a refreshToken. Your system is responsible for handling expiry and re-authentication, so build that in from the start rather than bolting it on later.
Step 2: Create the Meeting
Send a meeting type, a title, and a config object that governs participant behaviour.
POST /services/vcmeetingsettings/api-user/start-meeting
Authorization: Bearer <accessToken>
Content-Type: application/json
{
"meetingType": "instant",
"title": "Quarterly Review",
"preDefineHostEnabled": true,
"uniqueParticipantJoin": true,
"config": { "PASSWORD": true, "AUTH_USER": false }
}The response returns a meetingId, a meetingUrl for participants, a separate hostUrl that grants host privileges, and a password if you enabled one. Host and participant URLs are distinct, which is what stops an attendee from claiming host controls.
In Node.js, note that axios.post takes the request body as the second argument and configuration such as headers as the third. Passing headers inside the body is a common mistake and results in an unauthenticated request.
const axios = require('axios');
async function createMeeting(accessToken) {
const url = 'https://convay.com/services/vcmeetingsettings/api-user/start-meeting';
const body = {
meetingType: 'instant',
title: 'Quarterly Review',
preDefineHostEnabled: true,
uniqueParticipantJoin: true,
config: { PASSWORD: true, AUTH_USER: false }
};
const config = {
headers: {
Authorization: `Bearer ${accessToken}`,
'Content-Type': 'application/json'
}
};
const response = await axios.post(url, body, config);
return response.data;
}Step 3: Generate Per-User Join Links
If you set uniqueParticipantJoin to true, you can issue a separate link per person in one call.
POST /services/vcmeetingsettings/meeting/calender/generate-join-urls
Authorization: Bearer <accessToken>
{
"meeting_id": "0000019c-f0ee-b60c-0000-000000086688",
"hosts": [ { "userId": "1Awe2345", "name": "Moinul Islam" } ],
"participants": [ { "userId": "1ALe2349", "name": "Shahinuzzaman Shawon" } ]
}This matters more than it looks. One shared link for forty people gives you no attendance record and no way to revoke access for a single person. Per-user links give you both, and they slot cleanly into your own invitation emails or calendar integration.
Step 4: Schedule and End
For future sessions, the schedule endpoint takes epoch millisecond timestamps and an explicit timezone. Getting this wrong is the most common integration bug, and it appears as meetings that exist at the wrong hour for one party.
POST /services/vcmeetingsettings/api-user/schedule-meeting
Authorization: Bearer <accessToken>
{
"meeting_title": "Cardiology follow-up",
"start_time": "1701060600000",
"end_time": "1701064200000",
"timezone": "Asia/Dhaka",
"meeting_description": "Post-operative review"
}When the session finishes, close it with GET /services/vcmeetingsettings/api-user/end-meeting-by-unique-id?uniqueId=UNIQUE_ID. This is the step teams most often skip. Sessions left open remain joinable and continue to count toward concurrency limits, so drive it from a scheduled job rather than relying on someone remembering.
Note that Convay’s documented v6.2 API does not include webhooks. Meeting state is driven by your own scheduler and by the endpoints above, so design your system to own the timeline rather than waiting for callbacks. If event callbacks are a hard requirement for you, confirm availability with the vendor before committing.
Security Considerations
At minimum, require token-based authentication with expiry, password-protected sessions, an option to require authenticated users, and per-user join links. For regulated environments, add geographic access restriction, host and participant role separation, and a documented data residency position.
Configuration Flags That Matter
Convay exposes these as explicit flags in the config object. The same concepts appear across vendors under different names.
PASSWORDrequires a password to join, so a leaked link alone is not enough.AUTH_USERblocks guests entirely and permits only logged-in accounts.ALLOW_COUNTRYrestricts joining to approved countries, which is rare across vendors and matters for regulated sectors.PRTCPNTS_LISTset tohosthides the attendee list from participants.HOST_RECORD_STARTUPbegins recording the moment the host joins, removing reliance on someone remembering.PRTCPNTS_AUD_ENABLEDandPRTCPNTS_VDO_ENABLEDdisable participant microphones or cameras outright, useful for broadcast-style sessions.
Treat Join URLs as Credentials
Meeting join links frequently carry an access token in the query string. That is convenient, and it is also why these links deserve the same handling as a password. General JWT security guidance advises against putting tokens in URL parameters, because URLs get logged by proxies, stored in browser history, and pasted into chat threads. Bearer tokens work for whoever presents them, with no further identity check.
The practical rules are short. Generate links per user rather than sharing one. Deliver them over authenticated channels, not public pages. Keep validity windows short. Validate any redirect target before sending a user to it, which Convay’s own documentation calls out as an open redirect risk. Combine link distribution with PASSWORD or AUTH_USER so a forwarded URL alone does not grant entry.
Residency Is Not Sovereignty
Data residency is where data physically sits. Data sovereignty is whose law can reach it. These are different questions, and only the first appears on most vendor datasheets. A US-headquartered provider storing data in Frankfurt remains reachable under the CLOUD Act.
The compliance picture has sharpened. The EU AI Act reaches full enforcement in August 2026, with penalties reaching 35 million euro or 7 percent of global annual revenue, stacking on existing GDPR exposure. For organisations where this is binding, on-premise deployment is the only answer that fully closes the question, which is the basis of Convay’s digital sovereignty position. Encryption in transit, including end-to-end encryption, protects data on the wire but does not decide who gets into the room. That is what role-based access control is for.
Limits and Quotas
Every provider limits you, and the limits differ in kind rather than just size. The kind determines how you design your scheduler.
Zoom applies request-rate limits. Its documentation confirms that requests exceeding a threshold fail with HTTP 429, and developers on Zoom’s own forum report a daily ceiling around 100 create or update calls, with higher allowances on some plans.
Convay applies a concurrency limit instead. Its documentation states each user may host up to 10 active meetings simultaneously. Nothing constrains how many meetings you create across a day. What is capped is how many run at once, per user.
These two models fail in opposite ways, and both fail quietly until they do not. Under a request-rate cap, a nightly batch job dies partway through and half your users have no meeting in the morning. Under a concurrency cap, batch creation is fine, but a busy hour where eleven sessions overlap on one account gets rejected. Rate limits push you toward queuing and backoff. Concurrency limits push you toward distributing meetings across multiple host accounts.
Participant ceilings are a separate axis. Convay separates standard sessions from large-scale sessions that reach up to 10,000 participants, requested through a distinct bigMeeting flag with its own response shape. If you expect large sessions, confirm which code path serves them, because it is often not the default one.
Common Use Cases
- Telehealth: a booking system creates the consultation and emails a personal link to the patient and the clinician.
- Online education: a learning platform schedules class sessions and issues per-student links that double as an attendance record.
- Government and regulated meetings: committee sessions where geographic access restriction and on-premise deployment are procurement requirements rather than preferences.
- Client portals: a professional services firm attaches a meeting to each engagement, visible only inside the logged-in account area.
Evaluation Checklist
Take these into vendor calls. The answers separate serious options from demos.
- Is this a meeting-lifecycle API or a media SDK, and where does video render?
- How long are access tokens valid, and how does refresh work?
- Can we issue per-user join links, or is there one shared URL?
- Can we require authenticated users and restrict joining by country?
- Are host and participant privileges separated at the URL level?
- Is the quota per request, per day, or concurrent, and is it per user or per account?
- What is the participant ceiling, and does a large session use a different code path?
- Where is meeting data stored, and under whose jurisdiction does the company operate?
- Is self-hosted deployment available?
- What is retained after a meeting ends, including recordings, transcripts, and logs?
Frequently Asked Questions
What is a video conferencing API?
A video conferencing API is a set of HTTP endpoints that let your application create, schedule, join, and end video meetings programmatically. It removes the need to build media servers, network traversal, or recording infrastructure. Most return a join URL that your users open in a browser or app.
How long does it take to integrate a video conferencing API?
A working meeting-lifecycle integration typically takes a few days. The sequence is authenticate, create a meeting, distribute join URLs, and end the session. Media SDK integrations take substantially longer because you build and maintain the entire call interface yourself.
How do I ensure a secure video conferencing integration?
Keep credentials on your backend and never authenticate from browser code. Issue one join link per participant rather than sharing a single URL, deliver links through authenticated channels, and combine them with a password or an authenticated-users-only setting so a forwarded link alone does not grant entry.
Are video meeting join links secure?
Join links often carry an access token in the URL, so treat them as credentials. Security guidance advises against exposing tokens in URL parameters because URLs are logged and forwarded easily. Generate one link per participant, keep validity windows short, and validate any redirect target to avoid open redirect risks.
What limits should I check before choosing a video API?
Ask whether the limit is per request, per day, or concurrent, and whether it applies per user or per account. Request-rate caps and concurrency caps fail in opposite ways and require different scheduler designs. Also confirm the participant ceiling and whether large sessions use a different code path.
Can a video conferencing API be self-hosted for data sovereignty?
Some can. Self-hosted or on-premise deployment is the only option that fully removes foreign jurisdiction exposure, because data never leaves infrastructure you control. Region pinning inside a vendor cloud limits where data sits but does not change which government can compel access from the vendor’s home country.
What does Convay offer for video conferencing?
Convay is a meeting-lifecycle API with a documented REST interface covering authentication, meeting creation, per-user join link generation, scheduling, and ending sessions. It includes end-to-end encryption, role-based access control, geographic access restriction, AI transcription and meeting minutes, multilingual subtitles, large sessions up to 10,000 participants, and on-premise deployment for organisations with data sovereignty requirements.
Conclusion
Three things decide whether a video API integration goes well. Name the category before you compare vendors, because a meeting-lifecycle API and a media SDK solve different problems and no feature table rescues a wrong choice. Check the quota model before you design your scheduler, since request-rate caps and concurrency caps fail in opposite ways. And separate residency from sovereignty, because only one of those appears on most datasheets.
If you are evaluating a video conferencing API for a regulated environment, the fastest way to test these answers is against a real integration rather than a datasheet. Book a demo and we will walk through the endpoints, the config flags, and the deployment options against your actual requirements.
