+### Exchange Receipt
+
+This endpoint is used to exchange old or expiring receipts for fresh ones.
+
+The `iat`, `exp` and `kid` claims can change each time a receipt is exchanged.
+
+This means that fresh receipts can have more recent issued at times, further in the future expiration times, and be signed with new signature algorithms.
+
+Authentication SHOULD be implemented for this endpoint.
+
+Request:
+
+~~~ http-message
+POST /exchange/receipt HTTP/1.1
+Host: transparency.example
+Accept: application/cose
