A developer's experience with an API extends beyond its endpoints. A shipment-tracking API might have clear paths, valid schemas, and reliable servers, yet a retailer could still need several support calls to obtain credentials, struggle to reproduce a delayed shipment in the sandbox, and discover a usage limit only after going live. The endpoints work, but the integration remains difficult to build and operate.
Treating an API as a product means taking responsibility for that complete experience.
This chapter explains how to identify the outcome consumers need, design a useful onboarding path, support production integrations, and measure whether the API delivers value beyond successful HTTP requests.
