Walkthrough

A new documentation section detailing an OAuth token retry mechanism for protected backends has been added to the endpoint security documentation, covering automatic token renewal and retry flows upon 401 responses from backends, including configuration options and best practices.

Changes

Cohort / File(s)	Summary
OAuth Token Retry Documentation en/docs/manage-apis/design/endpoints/endpoint-security/oauth-2.0.md	Added comprehensive documentation section "Implementing OAuth token retry mechanism for protected backends" with configuration parameters, behavior description, and implementation best practices. Content appears duplicated in the diff.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Verify the OAuth token retry mechanism documentation is factually accurate and aligns with actual implementation
• Confirm the duplication is intentional or should be removed
• Check for consistency with existing OAuth 2.0 documentation style and formatting

Poem

🐰 A token that stumbles, we taught it to try,
When servers say "401," it'll bounce back on high!
With docs clear and bright, the path now is plain,
OAuth flows smoothly—no more failed refrain! 🔐✨

155-167: Well-structured introduction and feature overview.

The introduction clearly explains the feature purpose, and the key features section provides concise, benefit-driven bullets that align well with the existing documentation style and tone.

---

168-185: Configuration section is well-formatted and consistent with existing patterns.

The Format/Example tab structure mirrors the established pattern used elsewhere in the document (e.g., Redis configuration sections), and the example values are practical and realistic.

---

186-211: Comprehensive configuration parameters table.

The table effectively documents both parameters with clear descriptions of their purpose, conditional applicability, default values, and required status. The explanation of how expires_in is only applicable when retry is disabled is particularly helpful.

---

213-223: Clear explanation of parameter behavior and interdependencies.

The configuration behavior section effectively clarifies the relationship between the two parameters, and the info box appropriately emphasizes the critical note about when expires_in is applicable. This helps prevent misconfiguration.

---

224-239: Clear step-by-step workflow with appropriate safety guardrails.

The numbered steps provide a logical flow of the retry mechanism, and the warning box appropriately communicates the single-retry policy to prevent misconfiguration or misunderstanding of the feature's behavior.

---

241-254: Well-considered best practices and performance guidance.

The best practices cover the key implementation concerns (production readiness, backend compatibility, timeouts, and testing), and the performance note appropriately manages expectations about potential latency during token renewal.

---

155-253: No duplication found—review comment is invalid.

The verification confirms that the "Implementing OAuth token retry mechanism" section appears only once in the file (line 155) with no duplicate content. The "Key features" subsection also appears only once (line 161). The file structure is intact with 254 total lines. The original concern about duplication is unfounded.
