Catalyst

The official Eventication API (work in progress)

Use the Catalyst integration to export Eventication data (memberships, jobs, shifts) to an external system.

Setup in Eventication

Go to: Admin → Event → General → Event integrations → + (button) → Catalyst. If you can't find it, ask an Eventication admin to add it for you.

Admin validation required: this integration must be validated by an Eventication admin before it becomes active and before you can use the API key.

In the Catalyst integration screen, if it’s not validated you’ll see an “Action required” note with a link to contact Eventication.

Note that a Catalyst API key is scoped to an event. Each event needs another Catalyst integration.

API key / authentication

Once validated, you’ll see an API key in the Catalyst integration screen. Keep this key secret (treat it like a password):

• Do not commit it to git

• Do not paste it in screenshots / tickets

• Store it in your secret manager or encrypted environment variables

Authenticate every request with the Authorization Bearer header:

Authorization: Bearer YOUR_CATALYST_API_KEY

Base URL

All endpoints are hosted on the API domain:

• https://api.eventication.com

Example:

• https://api.eventication.com/catalyst/memberships

Access control per endpoint

Eventication admins can enable/disable access per endpoint in the Catalyst integration settings. If your API key is valid but an endpoint is not allowed, you will receive:

• HTTP 403 with { "error": "Access denied" }

Pagination

List endpoints are paginated to keep responses fast.

• Query param: page (1-based)

• Fixed page size: 100 objects per request

• The response includes meta:

  • page, per_page, total_pages, total_count, next_page, prev_page

Example:

• GET https://api.eventication.com/catalyst/memberships?page=2

Rate limiting

Requests are rate-limited:

• 10 requests per minute

• On limit: HTTP 429 with { "error": "Rate limit exceeded" }

Endpoints

GET /catalyst/memberships

Returns members (users) for the event.

• URL: https://api.eventication.com/catalyst/memberships?page=1

• Fields per item:

  • id

  • firstname

  • lastname

  • email_address

Response shape:

{
  "data": [
    {
      "id": 123,
      "firstname": "Ada",
      "lastname": "Lovelace",
      "email_address": "[email protected]"
    },
    ...
  ],
  "meta": {
    "page": 1,
    "per_page": 100,
    "total_pages": 42,
    "total_count": 4199,
    "next_page": 2,
    "prev_page": null
  }
}

GET /catalyst/work_jobs

Returns jobs for the event, including station and substation details.

• URL: https://api.eventication.com/catalyst/work_jobs?page=1

• Fields per item:

  • id

  • start_time (ISO8601)

  • end_time (ISO8601)

  • work_station_id

  • work_substation_id

  • Localized names (dynamic):

    • Job name: name_<locale>

    • Work station name: work_station_name_<locale>

    • Work substation name: work_substation_name_<locale>

Locales are included when the corresponding database columns exist (for example name_en, name_fr, name_nl, …). This makes it forward-compatible when adding more languages later.

Example item:

{
  "id": 987,
  "name_en": "Bar",
  "name_fr": "Bar",
  "name_nl": "Bar",
  "start_time": "2026-03-03T10:00:00Z",
  "end_time": "2026-03-03T12:00:00Z",
  "work_station_id": 55,
  "work_station_name_en": "Food & Drinks",
  "work_station_name_fr": "Repas & boissons",
  "work_station_name_nl": "Eten & drinken",
  "work_substation_id": 56,
  "work_substation_name_en": "Main bar",
  "work_substation_name_fr": "Bar principal",
  "work_substation_name_nl": "Hoofdbar"
}

GET /catalyst/work_shifts

Returns shifts for the event. A shift links a member to a job.

• URL: https://api.eventication.com/catalyst/work_shifts?page=1

• Fields per item:

  • id

  • work_job_id

  • membership_id

Example item:

{
  "id": 444,
  "work_job_id": 987,
  "membership_id": 123
}
