Turn API status codes, failure conditions, retry rules, and recovery actions into an error flow diagram for API documentation, incident runbooks, and client integration reviews.

List each status code with the failure condition and expected recovery action, then preview the flow. Keep user-fixable errors, authentication failures, conflicts, rate limits, and server failures in separate paths.
A useful flow includes HTTP status codes, stable application error codes, whether the client can retry, the user-facing action, and the logs, metrics, or alerts that help operators investigate.
Yes. Use the action column to describe retry rules such as retry once, retry with exponential backoff, honor Retry-After, or do not retry because the request is not idempotent.
Yes. Use AI for a first draft, then preview and adjust the result before publishing it in documentation.
Use a table for reference. Use an error flow diagram when reviewers need to understand branches, retry paths, fallback behavior, and where an incident should move from client handling to operational response.
API Error Flow Diagram turns status-code tables into a readable flowchart for API documentation, SDK handoff notes, support runbooks, and incident reviews.
Use it to separate validation errors, authentication failures, conflicts, rate limits, dependency failures, and retryable server errors so client teams know what to do next.
Keep the source rows next to the exported diagram so future API changes can update the flow without losing the original error-handling decisions.
Error handling is easier to review when status codes, client behavior, retry rules, and recovery actions are shown as a flowchart.
400 invalid input -> show field error
401 unauthorized -> refresh token
409 conflict -> reload cart
503 dependency timeout -> retry with backoffAn error flow diagram helps teams decide whether the same status code is being used for too many unrelated problems.
HTTP 409
code: inventory_lock_conflict
client_action: reload inventory and retry onceUse API Error Flow Diagram when you need to inspect source content visually before it becomes documentation, a pull request note, an incident write-up, or a handoff artifact. Turn API status codes, failure conditions, retry rules, and recovery actions into a clear error flow diagram.
Before exporting, check that labels are readable, relationships match the source, generated examples do not contain private data, and the preview still makes sense after you edit the input.
If the preview fails, reduce the input to the smallest complete example, confirm the format syntax, and then add sections back one at a time. Many rendering failures come from partial files, indentation mistakes, missing diagram headers, or copied snippets that depend on hidden context.
Treat the preview as a review surface rather than a source of truth. Generated diagrams, converted files, dashboards, and rule examples should be checked before they are used in production documentation or operations.
This tool extracts useful structure and relationships from developer input. Complex edge cases should still be checked against the source.
The maturity label is not a quality score. It tells visitors whether the tool is best for stable export, deeper debugging, quick parsing, or AI-assisted generation.
