API Development
API development at Spygar treats contracts as products—OpenAPI, auth, webhooks, retries, and partner docs for B2B stacks.
API Development
Custom REST/GraphQL APIs and third-party integrations. Ecommerce-specific work also maps to ecommerce API integration; SaaS partner APIs to SaaS API integration.
