Hi, I have a requirement of sending documents (filetypes like pdf, jpeg, xlsx, docx, ppt etc) from Appian to external system (AWS API) through integration object, so I want to know what is the maximum file size I can send it through an integration object. I have read in documentation that Appian supports file upload up to 1 GB, so will Appian supports sending file through integration object up to 1 GB as well? Also, if I want to upload a 1GB file through an uploader component, how much time the component will take to load the file into the interface from users local system. Will the users session be active till the 1 GB file upload to the interface completes? Thanks.

Hello, It is currently not possible to use OAuth 2 Client Credentials to authenticate towards Appian for one of our connected systems.. The following request is made to create the token: POST /suite/authorization/oauth/token?grant_type=client_credentials HTTP/1.1 Host: ... User-Agent: Go-http-client/1.1 Content-Length: 0 Authorization: Basic .... Accept-Encoding: gzip The grant_type is passed as query parameter No Content-Type HTTP header is present (The body is empty) Appian returns an error, because it expects the Content-Type HTTP header to be present: {"error_description":"Missing HTTP Content-Type header","error":"invalid_request","error_uri":"https:\/\/docs.appian.com\/suite\/help\/24.1\/Web_API_Authentication.html#client-credentials"} Can the check be changed in Appian, so that the header Content-Type is not required if the body is empty?

I am facing issue while using the SSH Key Pair authentication for SFTP. So when I am trying using Basic Credentials, I am able to establish the connection with Remote Directory and able to Send and Receive File. But for same username when I am trying through SSH Key Pair authentication I am getting error as ".filetransfer.sftp.SendFileOverSFTP - com.jcraft.jsch.JSchException: Algorithm negotiation fail". I have created Third-Party Credentials in Appian using the username only and uploaded the private key along with a constant associated with it. Here is my File Transfer Configurations CDT: 'type!{plugins.ps.appiancorp.com/.../}FT_Config'( serverHostName: "xyz.com", serverPort: 22, scsExternalSystemKey: "aws-cmd", usePerUserCredentials: false(), privateKeyFile: cons!MS_SFTP_USER_PRIVATE_KEY_FILE )

I need to generate a secure embedded link and need to put that in an Appian interface. I mimicked what given in this documentation here (https://help.sigmacomputing.com/docs/example-embed-api-and-url) and created an expression rule for the same. It works but there are some organization level restriction to not put up client id and client secret in constants. Could you please share any alternatives which can be used to store the credentials in Appian or any workaround for the same? I tried to look into Third Party Credentials store but it seems like it can be accessed via a plugin alone.

I'm trying to use encryptvalue() and decryptvalue() in my existing rule. The purpose of using this function is to encrypt a value before inserting to Appian Cloud Database and decrypt a value when reading it from Appian Cloud Database. When trying to use encryptvalue(), I got an error saying ```Expression evaluation error at function 'encryptvalue' [line 2]: This plug-in [com.appiansolutionengineering.encryption] is not registered to access secured values for the given external system key [encryptdecryptkey]. Check the external systems plug-ins list in the Administration Console.``` Currently, I don't have any third party credentials nor Plug-Ins registered. How to use encryptvalue() and is there any other work around for encrypting data in Appian Cloud Database?
