Does Apple provide an API to get pricing info of a product, configured under inapp purchase feature. (for auto renewable subscription)

We tried purchasing auto-renew subscription with and without free trial. Some times renewal does not happen in Sandbox after 5 mins. We checked the latest receipt even after 2-3 days, still there was no receipt. What can be the reason?

"latest_receipt_info" is missing from Receipt when fetched from Apple servers using verifyReceipt endpoint.Can anyone explaimn when can this arise, and what is the reason behind this. We see significant amount of the trxn resulting in this.Here is one such receipt.{ "receipt": { "receipt_type": "Production", "adam_id": "******", "app_item_id": "******", "bundle_id": "com.****.***.****", "application_version": "2.3.1", "download_id": "******", "version_external_identifier": "*******", "receipt_creation_date": "2019-06-19 16:15:05 Etc/GMT", "receipt_creation_date_ms": "1560960905000", "receipt_creation_date_pst": "2019-06-19 09:15:05 America/Los_Angeles", "request_date": "2019-06-20 08:45:52 Etc/GMT", "request_date_ms": "1561020352231", "request_date_pst": "2019-06-20 01:45:52 America/Los_Angeles", "original_purchase_date": "2019-06-19 16:15:05 Etc/GMT", "original_purchase_date_ms": "1560960905000", "original_purchase_date_pst": "2019-06-19 09:15:05 America/Los_Angeles", "original_application_version": "2.3.1", "in_app": [] }, "status": 0, "environment": "Production"}This is for Mac App Store. So i don't think that it is a old receipt (like iOS 6). Also it came while our QE was performing the test.
