Integrations

This is a Premium Only Feature

Integrations connect Curling IO with the external services your club already relies on, keeping data synchronized and automating tasks that would otherwise require manual exports or imports.

  • Mailchimp — Sync member contact details and registration tags to your marketing audience so mailing lists stay current.
  • QuickBooks Online — Accounting export automation is coming soon; this section will be updated once the workflow is live.
  • External Calendar — Mirror events from an iCal/WebCal feed (like Google Calendar) so your club calendar stays in step with league or facility schedules.

Finding Integrations​

Within your admin area, click on the Club dropdown menu in the top bar and then click on Integrations.

MailChimp​

Connect your Curling IO member and registration data to a Mailchimp audience so lists stay up to date without manual exports.

What gets synced​

  • Member profile fields map to Mailchimp merge fields when present: ID, EMAIL, FNAME, LNAME, PHONE, GENDER, DOB, PCODE, and mailing address components (addr1, city, state, zip, country).
  • Completed registrations add Mailchimp tags for the product name and, when applicable, the event category (e.g., Bonspiels).

Set up the connection​

  1. Navigate to Admin → Integrations and open the Mailchimp panel.
  2. Enter a Mailchimp API key (create one via Mailchimp’s API key guide).
  3. Provide the target Audience (List) ID (see Mailchimp’s audience ID instructions).
  4. Save. Curling IO verifies the credentials and begins syncing changes automatically.

The integrations page shows the last successful sync time and any recent Mailchimp errors.

Common errors​

  • “Data did not match any of the schemas described in anyOf” — A merge field in Mailchimp rejected the data. Make sure optional fields stay optional or match Curling IO formats (for example, phone numbers formatted like +1 403-555-1234).
  • “Invalid Resource”, “Member is in a compliance state”, “Permanently deleted” — The contact cannot be updated via the API. Ask the member to resubscribe directly through Mailchimp.
  • API key or datacenter errors — Confirm the API key is active and belongs to the same datacenter as the target audience.

QuickBooks Online​

The QuickBooks Online integration is coming soon. We will update this section as soon as the connection workflow is available.

External Calendar​

Import events from an external iCal/WebCal feed and display them alongside your Curling IO events.

Configure the feed​

  1. In Admin → Integrations, open the External Calendar panel.
  2. Provide the subscription URL for the iCal/WebCal feed you want to mirror.
  3. (Optional) Add a notification email to receive sync error alerts.
  4. Enable the integration to start nightly syncs. You can disable or re-run syncs manually from this screen.

Find your Google Calendar public URL​

  1. Open Google Calendar in a browser and click the gear icon → Settings.
  2. Under Settings for my calendars, pick the calendar you want to share.
  3. (Optional) If you want a publicly shareable feed, check Make available to public in the Access permissions for events section.
  4. In Integrate calendar, copy the Public address in iCal format.
  5. If you prefer to keep the feed private, use the Secret address in iCal format instead and keep it confidential.

Sync behavior​

  • Curling IO fetches the feed nightly using conditional requests (ETag/Last-Modified) to reduce traffic, and shows the last sync status and any failure messages in the integration panel.
  • Recurring events are expanded, cancellations are respected, and stale occurrences fall out automatically when they disappear from the feed.
  • Only events within the active sync window are stored; older items are purged after about three months to keep the view concise.
  • Sync failures trigger retries and, when you provide a notification email, send an alert so issues can be resolved quickly.

If the feed includes malformed entries (missing UID, DTSTART, etc.), they are skipped but reported in the integration status so you can follow up with the feed provider.
