aid: lexoffice url: https://raw.githubusercontent.com/api-evangelist/lexoffice/refs/heads/main/apis.yml name: lexoffice kind: company description: lexoffice (rebranded to "lexware Office" in 2025) is a German cloud accounting, invoicing, and bookkeeping SaaS from Lexware (Haufe Group). Its public REST API lets developers push and pull business data - contacts, invoices, quotations, order confirmations, delivery notes, credit notes, dunnings, bookkeeping vouchers, files, payments, and profile metadata - and subscribe to webhooks via event subscriptions. Authentication is a self-serve Bearer API key. The API gateway moved from api.lexoffice.io to api.lexware.io on 26 May 2025 as part of the rebrand; the legacy host remained available through December 2025. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Accounting - Invoicing - Bookkeeping - Finance - Germany - Vouchers - Contacts - SaaS - Financial Software created: '2026-07-12' modified: '2026-07-12' specificationVersion: '0.19' apis: - aid: lexoffice:lexoffice-contacts-api name: lexoffice Contacts API tags: - Contacts - Customers - Vendors image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://developers.lexware.io/docs/#contacts-endpoint baseURL: https://api.lexware.io/v1 properties: - url: https://developers.lexware.io/docs/ type: Documentation - url: https://developers.lexware.io/docs/#contacts-endpoint type: APIReference - url: openapi/lexoffice-openapi.yml type: OpenAPI - url: collections/lexoffice.postman_collection.json type: PostmanCollection - url: collections/lexoffice.opencollection.json type: OpenCollection description: Create, retrieve, list, and update contacts - customers and vendors with company or person roles, addresses, contact persons, email/phone, and bank details.
