Adopets

Adopets is an Adoption Management System (AMS) for animal shelters and rescues that streamlines the entire pet adoption process — online and in-person applications, approval and team collaboration workflows, digital kennel cards with QR codes, secure payment processing for adoption fees, licenses, products and donations, daily reporting and dashboards, and post-adoption communication. Backed by Techstars. Adopets exposes an External API (documented as a public Postman collection) that lets partner systems connect staff users and create, retrieve, change, cancel, and refund adoption payment requests and transactions on behalf of an organization, authenticated with an organization API key plus a per-session JWT bearer token.

Adopets publishes 3 APIs on the APIs.io network: payment-request API, payment-transaction API, and system-auth API. Tagged areas include Pet Adoption, Animal Welfare, Shelters and Rescues, Adoption Management, and Payments.

Adopets’ developer surface includes documentation, API reference, authentication, sandbox, and 17 more developer resources.
