Dear all, Apologies but it seems that I am getting the wrong apiKey from the test environment I am using. The correct apiKey is apiKey := '19aW5T6QBjOZFQOzygNAFA=='. which produces the appropriate results.
As stated by a number of you the SHA256 and base64 transformations work correctly. Thank you all for your efforts.
