  • This is a very useful plugin and we have used some of its functions for creation of a Shared Access Signature token required for REST API Intergation with Azure Service Bus. Much appreciate Appian's support with this Plugin

    Hi  Could you please let me know how you generated Shared Access Signature in Appian using this plugin? Because I used this plugin to generate SAS for Azure BLOB using the below code but the authorization header fails. Can you debug below code and let me know what i miss

    local!sampleSign:"GET\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:Fri, 23 Feb 2024 16:10:38 GMT\nx-ms-version:2015-04-05\n/mystorageaccount/mycontainer/myfilenamewithext",
    local!base64Key: decodebase64string(/*Access Key of Storage Account*/),
    local!unicodeSign: code(local!sampleSign),/*UTF-8 conversion*/
    local!hashKey: hmacsha256bytehash(
    key: local!base64Key,
    scsValue:{""},
    string: local!unicodeSign,
    returnBase64: true
    ),
    { touniformstring(local!hashKey) }
