AttendBeacon for developers

Build on your events

One REST API for registrations, the programme, check-in, sponsors, crew and money; signed webhooks the moment something happens; and an MCP server so your AI assistant can work with your events. Every example here uses Beacon Summit, the demonstration event.

Your first call

Make a key in the workspace under Integrations, API & MCP, then ask who you are:

curl "https://attendbeacon.com/api/v1/me" \
  -H "Authorization: Bearer $ATTENDBEACON_KEY"
