EGYM Pay with Wellpass API
Authorization-and-capture API for booking platforms. A Wellpass member generates a single-use booking code in the Wellpass app for a specific gym; the partner platform validates the code (dryRun true), then redeems it (dryRun false), which creates the booking and charges the member's Wellpass credit wallet, returning a payout amount. A cancel operation returns credits and is explicitly documented as idempotent. Currently available in France and Belgium only. Two operations, documented in prose with a 13-entry typed business-error registry — EGYM publishes no OpenAPI for this surface and the base URL is a {baseUrl} placeholder issued to partners at onboarding, so no public host exists to record.
