12 APIs for Virtual Events (2026)

In 2021, virtual event platforms were among the hottest software categories.

Hopin, the breakout name of the pandemic era, raised at a $7.75 billion valuation in August 2021. Two years later, it sold its core Events and Session platforms to RingCentral for $15 million, a collapse of well over 99% from peak valuation.

Why do we share this? It's an important reminder that the market has matured and consolidated hard since the pandemic-era boom, and a lot of the platforms and APIs from that period didn't survive. The API(s) you pick are a bet on a vendor's durability, and you want to ensure you're evaluating that alongside the feature list.

Below are 12 APIs that pass that quality test today, grouped by how you'd actually integrate them.

How to Evaluate a Virtual Event API

Before picking any API on this list for your virtual event app, it's helpful to know what to look for.

Consider:

Data portability: If a vendor folds, gets acquired, or sunsets a product line, can you actually export your attendee, registration, and engagement data? This matters more in this space than in most, given how many event platforms have been acquired or shut down since 2021.
Point solution vs. full platform: Some APIs let you integrate one specific capability into an existing build. Others effectively require you to run your event on their platform. Neither is wrong, but they're different commitments. Know which one you're making.
Real-time delivery model: Live events generate bursts of time-sensitive data, like a poll closing, an attendee checking in, or a session ending. APIs that push this via webhooks (Zoom, MeetingPulse) let your app react instantly; APIs that only support polling put the latency and infrastructure burden on you.
Traffic spike handling: Registration and engagement APIs both see extreme, predictable spikes. For example, everyone logs in five minutes before a keynote, or everyone votes in the same 30-second poll window. Check a vendor's published rate limits against your actual concurrent-attendee numbers.
Accessibility as a requirement: Multilingual support and live captioning used to be nice-to-haves; for many organizations, they're now compliance requirements. If your events serve a global or public-sector audience, evaluate translation/captioning support (see Interprefy below) at the same stage as registration and engagement.

With that framework in place, let's look at where each API lands.

Registration & Ticketing

Simplify the complicated business of registering attendees (and making sure they actually log on to your online event with calendar invites, notifications, and follow-ups) with these APIs.

Eventbrite API

What It Does: The Eventbrite API covers the full lifecycle of an event's data: Events, Orders, Attendees, Venues, Ticket Classes, and Order Questions. Beyond basic read access, it supports embedding a fully customized ticket checkout flow directly in a third-party site or app, rather than redirecting attendees to Eventbrite's own checkout page, and can notify your systems in near real time via webhooks when an order comes in or a ticket is refunded.

Integration Model: REST API returning JSON. Eventbrite itself changed hands recently; the company was taken private by Bending Spoons, with the acquisition completing in March 2026, ending its run as a publicly traded company (NYSE: EB) since 2018.

Best Fit For: Teams that want ticketing and checkout without building payment and order management from scratch, and are comfortable depending on a company now under new private ownership.

Explara API

What It Does: The Explara API provides ticketing and registration management beyond a single sign-up form. It handles per-session RSVPs (so an attendee can register for the keynote but skip a workshop), login/authentication for returning attendees, and profile management across an event's full schedule. It's built for events with multiple concurrent tracks or workshops rather than a single-session webinar.

Integration Model: OAuth 2.0 authentication; client libraries available in jQuery, Python, Ruby, and Go.

Best Fit For: Smaller teams or regional (particularly India-based) events where Explara's existing footprint adds a real benefit.

eZ-Event API

What It Does: The eZ-Event API ties event registration into the surrounding operational stack rather than treating it as a standalone form. Attendee details sync with email marketing campaigns, webinar tooling, CRM records, and a master event calendar, and each registrant is prompted to build out their own event profile and personal schedule as part of signing up.

Integration Model: Built by eZ-Xpo, which has repositioned itself since 2021 around AI-enhanced hybrid event capabilities layered on top of its existing virtual trade show and expo tooling.

Best Fit For: Teams running trade-show-style hybrid events who want registration tied directly into exhibitor and sponsor workflows, not just simple RSVPs.

Engagement & Interactivity

Unlike in-person events, virtual sessions don't have natural ambient engagement. These APIs actively build it back in.

Accelevents API

What It Does: The Accelevents API covers the full operational surface of running an event, including registration, badge/QR-based check-in, session scheduling, speaker and exhibitor profiles, and gamification mechanics (points, leaderboards, challenges) designed to keep attendees engaged across a multi-day conference. It's broad enough that some teams build an entire event platform on top of it rather than treating it as a single-purpose add-on.

Integration Model: REST API; components can be used individually (embed just check-in, for example) or combined to build a full custom platform.

Best Fit For: Teams that want the option to start with one feature and expand into a full custom-built platform over time, rather than committing to an all-or-nothing vendor.

MeetingPulse API

What It Does: The MeetingPulse API drives real-time audience engagement across 12 distinct modules, including live polling, Q&A, voting, surveys, brainstorming boards, sentiment analysis ("Pulse"), scheduling, custom forms, chat, and photo sharing. They're usable together as a full conference companion app or embedded individually where you only need one capability, like a single live poll widget on a slide.

Integration Model: API and SSO support are built in; the platform now also distributes through the Webex App Hub and Google Workspace Marketplace, meaning it can plug directly into meetings your team is already running rather than requiring a standalone embed.

Best Fit For: Teams running frequent internal or hybrid meetings (town halls, SKOs, association meetings) who want engagement tooling that meets people where they already are, in Webex or Google Slides.

Feedback & Surveys

Attendee, exhibitor, and sponsor satisfaction is hard to gauge live. These APIs handle collecting that feedback afterward.

Cvent REST API

What It Does: Cvent's unified REST API includes a Surveys resource for searching surveys tied to a given event and retrieving both the underlying questions and the responses submitted by attendees, exhibitors, or sponsors. It's one part of a single API that also covers registration, attendees, sessions, and more.

Integration Model: OAuth 2.0 client credentials, JSON. This replaces Cvent's older SOAP-based API, which the company's own documentation confirms is being sunset. This is good to know if any existing integration guides you find still reference the SOAP version.

Best Fit For: Teams already running event management, registration, or attendee data through Cvent's platform. Since surveys are just one resource within the same unified API, not a standalone integration, there's little reason to reach for this unless you're already building on Cvent for other reasons.

SurveyMonkey API

What It Does: The SurveyMonkey API offers general-purpose survey infrastructure that goes beyond simple data retrieval: programmatically adding, editing, or deleting individual questions and responses, and machine-translating an entire survey into another language for multilingual audiences. This is useful for a single global event running the same feedback survey across several regions without maintaining separate translated copies by hand.

Integration Model: RESTful API returning JSON responses.

Best Fit For: Teams that need a standalone, well-established survey tool decoupled from a specific event platform. This is great when your event stack is otherwise assembled from multiple point solutions.

Discovery & Distribution

Getting an event in front of people who don't already know about it is a different problem than registering the people who do. These APIs can help.

Ticketmaster Discovery API

What It Does: The Ticketmaster Discovery API lets developers search for events, attractions, and venues across the platforms Ticketmaster powers (Ticketmaster itself, Universe, FrontGate Tickets, and its resale marketplace), and retrieve event details, classifications, and ticket availability. This is nice to have for surfacing relevant public events to an audience rather than just managing registration for one event you're already running.

Integration Model: REST API authenticated via a simple API key query parameter. Self-service sign-up through Ticketmaster's developer portal gets you a working key immediately, with a default quota of 5,000 calls/day and 5 requests/second (higher limits available on request). Note: Ticketmaster's separate "International Discovery API" is being phased out and no longer accepts new key requests; use the main Discovery API instead, which covers global markets going forward.

Best Fit For: Apps or platforms that want to surface a broader calendar of public events (not just their own) to help users discover things to attend. This is a genuinely different use case than the registration-focused APIs elsewhere in this list.

Multilingual & Accessibility

This is a category that barely existed as an API-driven space in 2021, and has grown substantially since as virtual and hybrid events increasingly serve global, multilingual audiences.

Wordly

What It Does: Wordly offers AI-powered live translation and captioning that converts spoken audio into dozens of languages in real time, delivered as live captions, translated audio, or both. It's built specifically for conferences, webinars, and hybrid events rather than as a general-purpose translation tool.

Integration Model: A Captions API pushes live caption segments to a webhook URL as JSON while a session is active; separate REST APIs handle session creation, start/stop control, and glossary management, with live OpenAPI reference docs available to approved developer accounts. Pre-built integrations already exist for Zoom and Cvent.

Best Fit For: Events serving global or multilingual audiences that want translation/captioning either as a standalone service or layered into an existing platform via webhook, rather than committing to a fully managed, non-API vendor relationship.

Platform-Native APIs

These APIs aren't small add-ons you bolt onto something you've already built. Using them means running some or all of your event on that vendor's platform.

RingCentral Webinar API

What It Does: The RingCentral Webinar API is for full lifecycle webinar management, including creating, scheduling, and broadcasting webinars for up to 10,000 attendees, tracking who registered versus who actually attended, and retrieving encrypted recordings afterward.

Integration Model: REST API with SDKs in JavaScript, Python, PHP, and Ruby. Free for ISV partners building integrations for joint customers; otherwise included with a RingCentral Webinars subscription or available standalone starting at $75/host/month.

Best Fit For: Teams running large-scale, high-attendance webinars (product launches, town halls) who want registration, attendance, and recording data available programmatically rather than manually exported after the fact.

Brella

What It Does: Brella is an AI-powered attendee matchmaking and 1:1 networking API. It matches attendees based on stated interests and goals, and lets them schedule meetings directly through the platform, with the goal of driving higher-quality connections (and measurably higher meeting-acceptance rates) than a generic attendee directory would.

Integration Model: A documented Public API for pulling data out of Brella (attendee lists, meeting/networking activity) into your own systems. Note that per Brella's own help center, the API is read/data-access focused, and any custom display or functionality built on top of that data is on your own team to build. Also offers native, no-code integrations with common tools (Salesforce, HubSpot) and webhooks for real-time updates.

Best Fit For: Conferences and trade shows where structured, high-intent networking between attendees is the main draw.

Zoom Webinars Plus & Events API

What It Does: The Zoom Webinars Plus & Events API manages an event through Zoom's own data hierarchy. An Account contains Hubs (an organizer's overall event portfolio, like "Marketing Events"), each Hub contains Events, each Event contains one or more live Sessions, and each Session has Tickets representing individual attendee registrations. On top of that structure, the API supports granular actions like attendee check-in tracking and generating or revoking event access links.

Integration Model: OAuth 2.0 authentication with webhooks for real-time updates (session changes, attendee check-ins) rather than requiring you to poll for status. Requires a Pro-or-higher Zoom account plan and a Webinars Plus / Events license.

Best Fit For: Teams already standardized on Zoom for meetings who want event management built on the same account and infrastructure their organization already runs on, rather than adding a separate vendor.

Choosing Where to Start

These 12 APIs range from a single webhook (Wordly) to running your whole event on someone else's platform (Zoom, RingCentral).

Our recommendation? Treat registration and engagement as separate decisions. Point solutions are more resilient than an all-in-one bet. For example, swap out SurveyMonkey and nothing else breaks; swap out an all-in-one platform and you're rebuilding everything at once.

This list will age, too. We verified every entry against current docs, and still found APIs that had gone dark or changed beyond recognition. Re-check your dependencies the way you'd re-check any other part of your stack.
