Sync guests with your CRM

Push registrations to HubSpot, Salesforce or your own CRM and pull contact lists back in.

Build your own registration

Use your own forms and app, keep eventpage for tickets, check-in and messaging.

FAQ

Developer questions

What developers ask us before they integrate.

Need a hand with your integration?

Our team helps with architecture, auth and edge cases.

Contact the dev team

Which plans include API access?

API access is part of the Pro and Enterprise plans. Your API keys live in the workspace settings.

Is there a sandbox or test mode?

Yes. Next to your live key you can create a test API key and try every request without affecting real events, guests or payments.

How are rate limits handled?

Every workspace has clear rate limits. Each response includes headers with your remaining quota, and if you hit the limit you get HTTP 429 with a Retry-After header.

Do you offer SDKs?

You do not need one: any HTTP client works. Because the API is fully described in OpenAPI 3, you can generate a typed client for your language in minutes.

How do I authenticate?

Send your API key as a bearer token in the Authorization header of every request. Keys are scoped to a workspace and can be rotated or revoked at any time.

Can I use the API and the MCP connector together?

Yes. The MCP connector runs on the same API, so integrations and AI assistants work with the same events, guests and permissions.
