To validate a Jira workflow against an OpenAPI spec, run two separate checks: validate the API contract with OpenAPI-aware tooling, then validate the Jira workflow payload with Jira Cloud’s workflow validation endpoint. These checks cover different things; the Jira references reviewed do not describe a built-in validator that accepts an arbitrary OpenAPI document and proves a workflow conforms to it.
This guide covers Jira Cloud REST API v3. Jira Data Center may expose different APIs and behavior, so check the documentation for your deployment. The cited OpenAPI reference is version 3.1.0; confirm which version your project actually uses.

What each validation checks
OpenAPI describes an HTTP API contract: its operations, request and response formats, and schema constraints. An OpenAPI-aware tool can check that the specification is valid and that requests or responses meet the declared contract. The OpenAPI Specification 3.1.0 defines that contract format.

Jira Cloud REST API v3 documents separate validation operations for creating and updating workflows. This distinction follows from the scope of the two references; it does not mean Atlassian integrates an OpenAPI validator into Jira.
#1 Best Overall
| Check | What it answers | Where to run it |
|---|---|---|
| OpenAPI contract | Is the OpenAPI document valid, and do the relevant HTTP requests or responses match its declared operations and schemas? | In your build or client tooling, using an OpenAPI-aware validator. |
| Jira workflow | Does the workflow payload pass Jira’s workflow-specific validation? | Against the appropriate Jira Cloud workflow validation endpoint. |
| Workflow scheme and publication | Do issue-type mappings and scheme changes validate, and can a draft be published? | Against Jira’s workflow scheme and draft operations, where applicable. |
Validate the OpenAPI contract
Run an OpenAPI-aware tool in your build or client layer to validate the document and, where supported, check requests and responses against its schemas. This only establishes that the API contract passes the checks you run; it does not establish that a Jira workflow is acceptable to Jira.
- Check the OpenAPI version declared by your project rather than assuming it uses 3.1.0.
- Validate the operations and schemas relevant to the Jira integration you are building.
- Keep the tool’s contract result separate from Jira’s workflow validation result so a schema mismatch remains distinguishable from a Jira configuration error.
Validate a Jira Cloud workflow payload
The Jira Cloud REST API v3 reference documents these workflow validation operations:
Rank #2
| Operation | Endpoint | Use |
|---|---|---|
| Create validation | POST /rest/api/3/workflows/create/validation |
Validate a workflow payload for a create operation. |
| Update validation | POST /rest/api/3/workflows/update/validation |
Validate a workflow payload for an update operation. |
Choose the endpoint that matches the intended operation. Before implementing a request, consult the live Jira Cloud REST API v3 Workflows reference for the current request body, permissions, OAuth scopes, and response and error details. Those implementation details are subject to change; do not assume a payload copied from an example will fit your workflow or deployment.

- Send the Jira workflow payload to the matching validation endpoint for creation or update, using the current endpoint contract and the credentials and permissions it requires.
- Record the results separately as an OpenAPI contract pass/fail and a Jira workflow pass/fail. A pass in one layer is not evidence of a pass in the other.
Check workflow schemes when routing changes
A workflow definition and a workflow scheme are related but distinct. Atlassian’s Jira Cloud workflow schemes reference states: “A workflow scheme maps issue types to workflows.” A scheme can be associated with projects, so a change to issue-type routing warrants checking the mapping and project association—not only validating an individual workflow payload.
Rank #3
When the scheme is active
Atlassian’s workflow scheme drafts documentation says: “Editing an active workflow scheme creates a draft copy of the scheme. The draft workflow scheme can then be edited and published (replacing the active scheme).” For an active scheme, make and validate changes through its draft rather than treating workflow payload validation as a scheme-publication check.
Validate before publishing
The draft publish operation supports a validateOnly option. A successful validation-only request returns HTTP 204. Actual publication is asynchronous: follow the task location returned by the publish operation to monitor its progress. Check the current draft endpoint contract for exact request and response details before automating this step.
Rank #4
Make CI failures actionable
Report the validation layers as independent results. That way, a failure identifies whether the OpenAPI contract, Jira workflow payload, or—when the change affects routing—the scheme or publication step needs attention. A successful OpenAPI check does not validate Jira-specific workflow rules, and a successful workflow check does not validate the OpenAPI document.

Quick Recap
- OpenAPI result: whether the document and selected requests or responses satisfy the checks your OpenAPI tooling performs.
- Workflow result: whether Jira accepts the create or update validation request under the current endpoint contract.
- Scheme result: whether the mapping and draft publication checks pass when scheme routing is changing.
