Returns HTTP 200 if all cars were removed successfully, or HTTP 207 if one or more items failed. The response contains a `failures` list — each entry includes the license number and an error message for cars that could not be removed. Cars not present in `failures` were successfully removed. ## OpenAPI ````yaml delete /api/billing-accounts/{baId}/cars openapi: 3.1.0 info: title: Partner API description: > The Partner API provides a suite of endpoints designed to help partners and customers to manage users, vehicles and billing records seamlessly. Note: These endpoints are currently available in Europe, with expansion to new regions planned for 2026. ## Getting started & onboarding To begin integrating with our endpoints, you will need access to our environments. Please follow these steps: 1. Request access: Contact us at api-developer-portal@arrive.com or reach out to your designated point of contact. 1. Testing & Staging: Once registered, you will be provided with credentials for our Staging environment. This allows you to test your integration end-to-end in a safe, isolated environment. 1. Production: After successful testing in Staging, your point of contact will guide you through the promotion to the Production environment. Requests and responses are in JSON format. ## Request timeout All the endpoints have a default timeout of 60 seconds. ## Errors All errors match the standard response for errors as defined by the Problem Details for HTTP APIs specification RFC 9457: ```json { "type": "https://developer.easyparkgroup.com/openapi/fleet/overview/", "title": "Forbidden", "status": 403, "detail": "Access denied", "instance": "/api/billing-accounts", "timestamp": 1771232045624, "traceId": "55a47f36-cea3-4b01-92b6-8295c02ac302" } ``` version: '2026.01' servers: - url: https://fleet.staging.ezprk.dev description: Staging - url: https://fleet.europe.ezprk.net description: Production security: [] tags: - name: Billing Accounts description: Query Billing Accounts and their Billing Info Records. - name: Login description: Authenticate with the EasyPark API - name: Cars allowlist description: > Cars allowlist allows partners and customers to manage which vehicles are permitted to park under an account. By maintaining an allowlist of approved vehicles, you ensure that only authorized cars can be associated with a fleet. ## Two allowlist modes The API functionality supports two modes, and the right one depends on how your integration is structured: **Global allowlist** — A single allowlist applies across all customers connected to your integration. Any vehicle added to the allowlist is permitted for all customers under that integration. Use this if you manage a unified fleet and want one centralized list of approved vehicles. **Single Billing Account allowlist** — Each customer connected to your integration has their own individual allowlist. Vehicles must be added per customer, and a vehicle permitted for one customer is not automatically permitted for others. Use this if you manage multiple customers with distinct fleets that should remain separated. If you are unsure which mode applies to your integration, check with the team that set up your API access — the mode is defined at the integration level. paths: /api/billing-accounts/{baId}/cars: delete: tags: - Cars allowlist summary: Delete cars from a Billing Account description: > Removes one or more cars from the billing account by license number.
