WooCommerce & integrations
WordPress’s REST API can expose and modify application data using JSON, but the business integration still needs permissions, validation, ownership and failure handling around the endpoints.
Direct answer
Use the WordPress REST API when another application needs structured access to WordPress data. Keep private resources authenticated, validate and sanitize input, store secrets server-side, and design retries so duplicate requests do not create duplicate business records.
Answer scope
WordPress REST resources can expose public content anonymously while protected data requires authentication and permissions.
Custom endpoints should implement explicit permission callbacks rather than assuming an obscure URL is private.
Custom post types, metadata and business records need a stable schema.
The API contract should specify required fields, allowed values and error responses so client applications do not rely on undocumented behavior.
API keys and client secrets should not be embedded in browser JavaScript or exposed in public logs.
Use environment configuration or another appropriate secret store and rotate compromised credentials.
A client can retry after a timeout even when the first request actually succeeded.
Use stable request identifiers or application-level deduplication where repeated creation would be harmful.
Verify not only HTTP status codes but the resulting record, permissions, notifications and downstream actions.
Include unavailable API, invalid data and expired-authentication cases in acceptance.
Questions
Yes. WordPress provides a JSON REST API for core resources and custom extensions.
Yes with appropriate authentication and permissions. Public and protected resources should be deliberately separated.
Secrets should be kept server-side with appropriate access controls; the exact storage depends on hosting and deployment architecture. Avoid exposing them to browser code or public repositories.
