GymMaster Gym & Fitness Club Management API

Export members, clubs, class schedules, membership types, bookable services, sales reps, KPIs and standard reports from your own GymMaster site, using your own GymMaster API keys (bring your own key).

Status (2026-10-22): live mode follows GymMaster's public API documentation as of 2026-10-22 (the Member Portal API and the KPI, Reporting and Dashboard API V2). It has not yet been verified against a real GymMaster account. If something does not work with your site, open an issue with the error row and it will be fixed.

How it works

GymMaster has no shared API host. Every club has its own site at https://<site name>.gymmasteronline.com, and the API lives on that host. You give the actor your site name and your keys, and it calls only the documented read endpoints:

API	Docs	Authentication
Member Portal API	gymmaster.com/gymmaster-api	api_key query parameter. Key from Settings > Integrations
KPI, Reporting and Dashboard API V2	gymmaster.com/gymmaster-reporting-api	X-GM-API-KEY header. Key from Settings > Integrations > Report API > API Key

If you do not see these keys under Settings > Integrations, ask GymMaster support to enable API access for your site.

Tasks

Task	Key	GymMaster endpoint	What you get
get_members	Member Portal	GET /portal/api/v1/members	All current members. startDate limits to members updated after that date, siteId to one club
get_sites	Member Portal	GET /portal/api/v1/companies	The clubs set up on your site (id, name, billing provider)
get_classes	Member Portal	GET /portal/api/v1/booking/classes/schedule	The class schedule for 7 days from startDate (default: this week)
get_memberships	Member Portal	GET /portal/api/v1/memberships	Membership types available for purchase, with prices and fees
get_facilities	Member Portal	GET /portal/api/v1/booking/services	Bookable services for one club. Requires siteId
get_staff	Member Portal	GET /portal/api/v2/staff/salesrep	Staff set as sales reps
get_reports	Report API	POST /api/v2/report/kpi/categories	All KPI categories for the period (member statistics, activity, sales, payment methods, bookings, classes). With reportId: that standard report
get_billing	Report API	POST /api/v2/report/kpi/categories	The sales_made and payment_method KPI categories for the period
get_bookings	Report API	POST /api/v2/report/standard_report	Rows of the "All Bookings" standard report for the period (or reportId)
get_door_entries	Report API	POST /api/v2/report/standard_report	Rows of your visits or door report for the period. Set reportId if the actor cannot find one by name

For get_bookings and get_door_entries the actor first lists your standard reports (GET /api/v2/report/standard_report/list) and picks the matching one. If none matches, the error row lists every report id and name on your site so you can set reportId.

Example

{
  "task": "get_members",
  "siteName": "myclub",
  "apiKey": "YOUR_MEMBER_PORTAL_API_KEY",
  "startDate": "2026-09-01",
  "limit": 1000
}

Output

One dataset row per run. Records keep GymMaster's own field names:

{
  "task": "get_members",
  "success": true,
  "demoMode": false,
  "data": {
    "items": [
      { "id": 1234, "firstname": "Alice", "surname": "Smith", "email": "alice@example.com", "joindate": "2025-02-01", "totalvisits": 87, "totalclasses": 12 }
    ],
    "count": 1,
    "totalReturned": 1,
    "source": { "api": "Member Portal API", "host": "myclub.gymmasteronline.com", "endpoint": "/portal/api/v1/members" }
  },
  "timestamp": "2026-10-22T12:00:00.000Z"
}

KPI tasks return data.kpis exactly as GymMaster sends it, plus the categories and date range used. If GymMaster rejects the request, the row has "success": false and an error message that includes GymMaster's response, and the run is marked failed. API keys are never written to the dataset or the log.

Pricing

Pay per event. Prices match the live pricing on Apify:

Event	When it is charged	Price
Actor start	Once when the run starts, one event per GB of memory (minimum one). At the default 1 GB of memory that is $0.10 per run	$0.10 per GB
Member Query	Retrieve member profiles, status, and access levels	$0.01
Door Entry Query	Access control logs with entry/exit times	$0.01
Booking Query	Get class and facility reservations	$0.01
Billing Query	Retrieve membership fees and payment history	$0.01
Membership Plan Query	Access plan pricing and terms	$0.01
Class Query	Get group fitness schedule and attendance	$0.01
Facility Query	Retrieve equipment and room availability	$0.01
Site Query	Access multi-location management data	$0.01
Staff Query	Get employee data and access permissions	$0.01
Report Query	Retrieve usage analytics and financial reports	$0.01
Result	Each item written to the default dataset	$0.00001

No task event is charged for sample runs, for runs that stop with an error (bad key, wrong site name, invalid input), or for live queries that return nothing. Apify still charges the Actor Start event on every run and the Result event for each dataset row.

Troubleshooting

"GymMaster rejected the ... key" or "GymMaster API error: ...": the key is wrong, belongs to another site, or is the wrong kind. Portal tasks need the Member Portal key, report tasks need the Report API key.

"Could not reach ...gymmasteronline.com" or HTTP 404: check siteName. It is only the subdomain, without https:// or .gymmasteronline.com (both are accepted and stripped).

"No standard report matching get_door_entries": copy a report id from the list in the error row into reportId.

---

Running without credentials

Without any API key (or with demoMode on) the run succeeds and returns a small sample dataset marked with "demo": true and a _notice field. It shows the output format only, it is not your data, and it charges no task event.
