How to Integrate the ABC Glofox API (2026)

ABC Glofox is the studio and gym platform in ABC Fitness's product family; ABC's own site lists it next to ABC Ignite, ABC Trainerize and ABC Evo. Glofox publishes an API reference on its API portal, and this guide is written from that reference (version 2.3.0) as it stood on October 17, 2026.

Sourcing note. The reference is a long static page; we read its navigation and its introductory sections (introduction, authentication, errors, branches and the first endpoints). The rest of the portal, including its "Request access" section, is a JavaScript application that returned no readable text to our fetch. How access is granted, and any rate-limit numbers or fees, are therefore not covered here.

What the API covers#

Glofox introduces its API as "a REST API that lets integrations manage members, memberships, credits, classes, bookings, and payments", with JSON responses. The reference groups endpoints like this:

The reference page offers a download of the underlying OpenAPI specification, which is the quickest way to generate a typed client.

Authentication: three headers on every call#

Every request carries three headers:

Glofox's instruction is blunt: "Always proxy API key and token requests through a secure backend. Never expose credentials in client-side applications." So a member-facing app calls your server, and your server calls Glofox.

Requests go to the production server shown throughout the reference, https://gf-api.aws.glofox.com/prod, followed by a versioned path such as /2.0/branches/{id} or /v3.0/locations/retrieve:

curl "https://gf-api.aws.glofox.com/prod/2.0/branches/YOUR_BRANCH_ID" \
  -H "x-glofox-branch-id: YOUR_BRANCH_ID" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "x-glofox-api-token: YOUR_API_TOKEN"

Branches and namespaces#

Two words carry most of the data model:

• Branch. Glofox defines a branch, also called a studio or location, as a physical location with its own set of members and staff.
• Namespace. A group of branches assigned to your integration. POST /v3.0/locations/retrieve returns the branches in your integration's allowed namespaces, all of them if you pass no filter, and Glofox says it filters access by the integrator's configured permissions.

Member search works across a whole namespace: the namespace is taken from the branch in your x-glofox-branch-id header, and the same email or phone can return more than one member when it exists at several locations. Phone search is an exact match on the member's normalized E.164 number and excludes staff. Plan your identity mapping for that before you merge members across locations.

Errors, including the 200 that is really a 400#

The reference lists the status codes to handle: 400 for invalid input, 401 when the request is not authenticated, 403 when the client lacks permission, 404 for a missing resource, 429 when "the API blocks the request when you exceed the rate limit", and 500 for server-side problems. Error bodies carry a human-readable message and a message_code meant for client-side handling.

One quirk to code for: Glofox says older endpoints "sometimes return a 200 status code with a success field set to false", which indicates a bad request, and recommends middleware that maps those responses to 400. In our experience this is the bug that slips through testing, because the happy path never sees it. Check success on every response from the older /2.0 endpoints, not just the status code.

The introductory sections we read do not state the rate limit itself. Treat 429 as the signal and retry with backoff.

Webhooks#

The reference's navigation lists webhook events for access, bookings, course bookings, electronic agreements, events, invoices, members, memberships, services and push notifications. We did not read those sections in full, so check the reference and the portal for how to register an endpoint and what each payload carries. For processing webhooks safely, see ingesting webhooks reliably.

Access and the wider ABC ecosystem#

The portal's navigation has a "Request access" entry, but the process behind it sits in the part of the portal we could not read. If you plan to sell an integration across ABC's product family, ABC Fitness also runs a partner program for app partners and solution providers. Its requirements and tiers are summarized in our gym and studio software API comparison.
