I'm integrating a South Korea API into my app.

Provider: PortOne
Auth: requires an access token (sign up: https://developers.portone.io/api/rest-v2)
Pricing: freemium
Base URL: https://api.iamport.kr
Important note: Aggregator: integrate once and switch between Korean PGs (KG INICIS, Toss, KakaoPay, NICE) without re-coding.

Source: PortOne (https://developers.portone.io/api/rest-v2)
Source type: Provider API or developer docs
Endpoint type: Provider API base URL

Last checked: 2026-07-05
Production caveat: Keep credentials server-side and confirm current limits, pricing, and webhook/error behaviour in the provider docs.

Help me set up the correct onboarding/authentication path and make the first valid request ~ explain exactly where credentials go and what must happen before production.
