aid: growthzone url: https://raw.githubusercontent.com/api-evangelist/growthzone/refs/heads/main/apis.yml name: GrowthZone kind: company description: GrowthZone is association management software (AMS) for chambers of commerce, trade and professional associations, and member-based organizations - covering membership management, member and organization contacts, event registration, invoicing and scheduled billing, member directories, certifications, and communications. The GrowthZone REST API (base https://{subdomain}.growthzoneapp.com/api) exposes this data programmatically for CMS/directory embeds, SSO, and mobile integrations. It is a partner/customer-gated API - access requires an account with API Access enabled and an API Key issued by GrowthZone WebSupport - and is documented publicly at integration.growthzone.com. GrowthZone also operates ChamberMaster and MemberZone, which expose a separate legacy REST API. OAuth 2.0 / OpenID Connect is supported for SSO. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Association Management - AMS - Membership Management - Chambers of Commerce - ChamberMaster - Member Directory - Events - Billing created: '2026-07-05' modified: '2026-07-05' specificationVersion: '0.19' apis: - aid: growthzone:growthzone-contacts-api name: GrowthZone Contacts API tags: - Contacts - Members - Organizations image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://integration.growthzone.com/growthzone-api/ baseURL: https://{subdomain}.growthzoneapp.com/api properties: - url: https://integration.growthzone.com/growthzone-api/ type: Documentation - url: https://documentation.growthzoneapp.com/CuratedApi.html type: APIReference - url: openapi/growthzone-openapi.yml type: OpenAPI - url: collections/growthzone.postman_collection.json type: PostmanCollection - url: collections/growthzone.opencollection.json type: OpenCollection description: Retrieve and page contacts - both individuals (persons) and organizations - with related addresses, emails, websites, categories, notes/custom fields, group memberships, and a delta feed of contacts changed since a given date.
