BigMarker

API and webhooks

BigMarker has a REST API with documentation. You can list, create, edit and delete conferences, register and unregister users, and let people attend from your own website. API access is listed from the Enterprise tier. Check the API reference for webhook support.

One idea: when someone signs up through your own form, register them for the webinar through the API, so they never see a second registration page.

Native integrations

The vendor describes CRM and marketing automation integrations that capture attendee data and sync it to your CRM. One idea: after a webinar, send attendees who stayed past the halfway mark to a follow-up sequence in HubSpot, and the no-shows to a replay email.

MCP server

I found no official MCP server yet. For agents, the API is the route.
