One session

--url https://example.com/api/sessions/0193f6c1-7a2e-7b4d-9f01-2c3d4e5f6a7b \
--header 'Authorization: Bearer <token>'

Everything the dashboard shows of a session: the split verdicts, the ack triples, the serving PSP, the notification calendar — and everything you sent with the order: the basket, the customer, the addresses, the travel details, the URLs. Another merchant’s session answers the same 404 as a nonexistent one.

sessionId
required

/^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/

Example
0193f6c1-7a2e-7b4d-9f01-2c3d4e5f6a7b

One session in full: the dashboard view, plus everything the merchant sent with the order — basket, customer, addresses, travel, return and cancel URLs, descriptor.
