Steps
After uploading the establishment's Form 300A summary and any Form 300/301 case records via the Case Data API, finalize the reporting period with `POST https://www.osha.gov/oshaApi/v1/submissions`, sending `establishment_id`, `year_filing_for`, and (for resubmissions) a `change_reason`, with `Authorization: Bearer {ITA API Token}`.
Read the response for the generated submission `id` and confirmation that `form300A` and (if present) `caseData` links were included.
Retrieve a previously completed submission with `GET /oshaApi/v1/submissions/{submissionId}` to audit what was filed.
Check whether the response includes a `caseData` property — establishments that only submitted 300A summary data (no case-level detail) will not have this property.
Use the `links` object in the response (`self`, `establishment`, `form300A`) to navigate to related resources without hardcoding URL patterns.
Known gotchas
`POST /oshaApi/v1/submissions` is an existing endpoint whose behavior changes only for establishments that have case data attached — establishments without case data see identical behavior to the legacy 300A-only flow.
The `caseData` property in the submission response is conditional — don't assume it's always present, or your parser will break on establishments without case-level detail.
This endpoint marks the entire reporting-period submission (summary + case detail) complete; it is separate from adding/editing individual case records via the Case Data endpoints.
