I'm integrating a Switzerland API into my app. API: Swiss Post ~ address, parcel & tracking APIs Provider: Swiss Post (Die Schweizerische Post) Auth: requires OAuth credentials (sign up: https://developer.post.ch/en/api-and-documentation) Pricing: paid Important note: Real, well-documented REST APIs but usage needs a Swiss Post business/billing account. Source: Swiss Post (Die Schweizerische Post) (https://developer.post.ch/en/api-and-documentation) Source type: Provider API or developer docs Endpoint type: Docs-first integration Integration difficulty: Needs OAuth Last checked: 2026-07-05 Production caveat: Keep credentials server-side and confirm current limits, pricing, and webhook/error behaviour in the provider docs.
