Ingest xAPI statements into an LRS

Verified steps

1. Provision or select an LRS that conforms to the xAPI specification (1.0.3 is the current stable version); note the LRS's statements endpoint URL (typically https://lrs.example.com/xAPI/statements) and authentication credentials.
2. Construct a valid xAPI statement as a JSON object with at minimum an actor (with objectType, name, and mbox or account), a verb (with id URI and display map), and an object (with objectType and id); add result, context, and timestamp fields as required by your use case.
3. Send the statement to the LRS via HTTP POST to /xAPI/statements with Authorization: Basic base64(key:secret) (or Bearer token if the LRS supports OAuth), Content-Type: application/json, and X-Experience-API-Version: 1.0.3 header.
4. For single idempotent statement submission, use HTTP PUT to /xAPI/statements?statementId={uuid} with the same headers; the LRS returns 204 on success and 409 Conflict if a statement with that UUID already exists with different content.
5. Batch multiple statements by sending a JSON array in the POST body to /xAPI/statements; the LRS returns an array of the newly assigned statement IDs in the same order.
6. Query stored statements via GET /xAPI/statements with filter parameters such as agent, verb, activity, since, and until to verify ingestion and support analytics; the LRS returns a StatementResult envelope with statements array and more URL for pagination.
