Avis Budget Group Rental Cars API
REST API (v2) for the Avis, Budget and Payless rental car brands: keyword search of rental locations, vehicle availability and rate shopping (including inclusive rates, coupons, memberships and secondary-currency pricing), reservation create, view, update, partial-modify and cancel (including paperless-voucher processing), and location terms and conditions. OAuth 2.0 client-credentials bearer tokens; every endpoint documented on the portal runs in the staging/pre-prod environment and production credentials are issued after ABG approval.
