The easiest docs to automate are the ones you can trace back to something true. An API spec can tell you that a field is required. It cannot tell you whether a customer should use that field for their workflow. Generate the first fact. Draft and review the second.
1. Match the source to the output
| Input | Useful output | Keep a human in charge of... |
|---|---|---|
| OpenAPI contract | Endpoint reference, request types, and response schemas | Whether the examples work and the defaults are safe to recommend |
| Pull request or release note | A short change summary and a list of affected guides | What shipped, who can use it, and what changed for existing customers |
| Recurring support tickets | Candidate FAQ or troubleshooting article | Redaction, accuracy, and whether the answer should be public |
Start with one trigger, such as a pull request changing your OpenAPI spec. Automating everything at once makes it harder to tell which source introduced a bad answer.
2. Ask for a change set, not a new site
Give the automation a copy of the previous and current sources. Ask it to return affected URLs, the supporting source for each proposed change, and a draft diff. It should be able to say “no public documentation change needed” when a pull request only touches internal behavior.
For ticket-driven drafts, use sanitized patterns, not raw transcripts. For example, “three workspace owners could not find the retry button” is enough to justify checking the article. The customers' messages and account identifiers do not need to leave the support system.
3. Walk one real change through the pipeline
Suppose a release adds a new way to retry failed webhooks:
- Regenerate the endpoint reference from the updated contract.
- Draft a change to the webhook recovery guide using the merged code and release note. Flag anything the sources do not establish, such as role requirements.
- Run the new request against a test environment. Have the feature owner verify permissions, failure cases, and whether the guidance applies to existing customers.
- Preview the guide and reference together. Publish when the feature is available, then check the canonical pages and links.
You end up with one new reference operation and a small update to an existing guide, not a second article that competes with it. To catch drift after that first publication, use the API docs sync workflow.
4. Track what the process saves, and what it misses
Start with the time between shipping a product change and publishing correct docs. Also count drafts that needed substantial edits and changes the automation failed to flag. If reviews take longer than writing the update yourself, reduce the scope or improve the input before generating more.
If your first source is an API contract, see what an OpenAPI documentation generator can produce and how to generate a TypeScript SDK from the same spec. If your first source is the support queue, start with the customer support automation guide.
