Verified steps Build a statement JSON object containing actor (with exactly one identifier like mbox or account), verb, and object. Use PUT to the LRS's /statements endpoint with a client-generated statementId query parameter for idempotent, retry-safe submission. Use POST to /statements when it's fine to let the LRS assign the statement ID itself. Set the X-Experience-API-Version header explicitly to either 1.0.3 or 2.0.0 depending on which spec version your LRS and statements target. Set Content-Type: application/json and an Authorization header (Basic or OAuth) as required by the LRS. Known gotchas Omitting X-Experience-API-Version causes most LRSs to reject the request outright. Reusing a statementId across different statement content (or PUTing without one) triggers a 409 Conflict. xAPI 2.0 (now IEEE 9274.1.1-2023) tightens several 1.0.3 "SHOULD" rules into "MUST" — a 1.0.3-valid statement isn't guaranteed 2.0-conformant.
