Summary

Document all eight channel-owned dedicated integration management APIs, including request/response schemas, examples, App Key scopes, channel permissions, private-channel access, masked settings, key rotation, and concurrent-change errors.

Separate public and dedicated integrations in the bilingual API navigation and catalogs. Clarify the existing public integration page titles while preserving their operation IDs and URLs. Keep module specs, consolidated specs, API counts, and redirects synchronized.

Known plugin_type values can be used to create dedicated integrations directly. Type lookup is optional and requires Integrations Read permission.

Validation

• python3 scripts/lint_openapi.py — all 12 spec files passed.
• python3 scripts/api_path_redirects.py --check and git diff --check passed.
• Verified identical new endpoint structures across languages and module/consolidated specs; every new endpoint appears once per language in navigation and catalog.
• Simplification review, uncommitted review, and full-branch review passed.
• Full-site mint validate reports 36 existing syntax warnings in unchanged integration MDX pages. An unmodified main archive reproduces the same 36 warnings.
• Full-site mint broken-links stops at the same unchanged apimetrics.mdx syntax error on both main and this branch.
• mint validate passed in an isolated API-reference preview containing the updated specs, navigation, and catalogs.
