Good afternoon everyone, As a Microsoft Power Platform Low-Code developer, I don't have any experience with creating Appian applications. Is it possible to create an Appian application on top of data that's stored in Dataverse? Or would it be more advantageous to migrate our data from Dataverse to, for instance, SQL? Thanks in advance!

Hi,  we have a problem connecting from Appian to an external URL (for es: https://ourserver.spid.local/service). Initially there was a problem of conflict between the URL's IP and some internal appian IP.   The connection from appian to the url is through a static VPN and  I have correctly  trusted the domain spid.local and the IP of the server in the VPN configuration details. The internal CA which signed the url's certificate is trusted in appian. When we Try to connect to the URL we  receive the error: "Certificate for <esternal URL> doesn't match any of the subject alternative names: [*.appiancloud.com, appiancloud.com]" How can we fix it? Thanks for your help. V

Hi All,    I'm using a http connected system with OAuth Client credentials type authorization. When I Authorize from connected system, It is authorizing successfully. But when I tested the Integration using this connected system, It is throwing an error as this Invalid credentials error-result-guidance Appian was not able to authenticate with the access token you provided. This request requires Bearer authentication. HTTP/1.1 401 Unauthorized Next Steps This integration is using a connected system with OAuth 2.0 Client Credential authentication configured. You may need to authorize access to the external system and retry the request. Make sure that you are using the correct OAuth 2.0 configuration for this external system Make sure that the OAuth 2.0 configuration provides the required scope to make this request Check the request and response for more details Review the external systems documentation for information on what may have caused the problem.

I am getting this error on Export to Excel function when I am exporting the data in excel via SQL query-  The following error was raised by the Export to Excel function: Attempting to write a row[4] in the range [0,157943] that is already written to disk. We have this functionality where there is a Create and Modify workflow and we want to create a excel template in both scenarios using SQL query. The strange thing is  - We are using same excel base template on both Create and Modify workflow but this error only occurs when executing Modify workflow. We have formula on A column which is populated on 4th row and excel headers till 3 rows so the starting cell is B5.  Can anyone please help me out to understand the root cause here?

Hi, we are attempting to use the Appian PowerBi plugin.  We are able to successfully connect.  However, when we attempt to use operations like "Get all Groups" we are getting error code 401 unauthorized.  I would appreciate any help. Here's a screenshot of the error:

I am using the AWS Assume Role plugin with the Amazon S3 plugin. Entering the credentials (e.g., Access Key, Access Key Secret, Role ARN, Role, etc.) directly in the Appian designer console when creating the connected system is non-ideal. An ideal solution would be to natively integrate with AWS Secrets Manager, which would allow for automated secrets rotation. In the interim I would like to use Appian's SCS. How can I inject the secrets in the Assume Role Plug-in using the SCS? From what I've read the Third Party Credentials can only be used by Java plugins. Do I need to create a new plugin? Do you have an example that goes through this kind of use case step-by-step? This is the only documentation I've found -- how would the custom plugin then inject the secrets into the AWS Assume Role plugin?

Hi, Which jar I need to import to get classes of  com.appiancorp.services package? Below are the jars I have in my system.

I'm trying to integrate with a SOAP call where the only credentials in the header is the current datetime: <soapenv:Header> <sec:Credentials>      <sec:Created>2024-03-12 17:44:34Z</sec:Created> </sec:Credentials> </soapenv:Header> How do include that information in the header?  I'm calling the webservicequery, but I can't figure out how to include that header information.  I would guess I would use a wsHttpHeaderField, but how to I make it nested with the two layers of information?

I have a Sharepoint connector defined and authenticated with an integration that uses it. It is set to create a folder. I am trying to use it in an expression like so:a!localVariables( local!user: rule!HR_getUserFromUuid(ri!uuid), local!employeeFolder: upper(user(local!user, "firstName")) & " " & upper(user(local!user, "lastName")), rule!HR_SharepointCreateFolder( folderName: local!employeeFolder, rootPath: cons!HR_SHAREPOINT_EMPLOYEES_FOLDER ) )It however doesn't create the folder. If I go to the integration, enter the same values as test inputs and click test, it does work as expected.

We will going to use Appian to remediate one of application. We will need to fetch data from Appian db and load it into our in house database, In our existing set up, where Appian is not used , we are using informatica Power centre to fetch data from external vendor application via CData ODATA connector. Is there any way to do with Appian also?

Hi Everyone, In our environment we are using 'Chart creator' to create charts. Is this plugin still functioning in appian? i know that we have chart generator plugin to generate charts.

Hello fellow devs, I have a requirement, but I'm unsure if Appian supports it. I need to set up an integration that involves using certificates. Specifically, one of the certificates is meant to encrypt the payload. If I upload the appropriate certificate in the admin panel, will Appian automatically understand that the payload needs to be encrypted when sending an integration request? Let me know if you need more info. Thanks!

Is it possible to apply the Adobe Sign e-signature based on an Appian button? If so, is there any documentation related to this?
