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?

Hi,  We have to retrieve the third party credentials from an external repository but the client doesn't want developers (not even administrators) to have access to these credentials.  We know that credentials in the connected systems are masked: And we also know that values can be masked in Third Party Credentials (but this has to be done manually by an administrator):  Does anyone know if this can be done dynamically or if there is a way for developers to not have access to these credentials? Thanks!

Hi, I'm trying to post a webhook on Autodesk which callbackurl is an Appian web API. The problem I have, I can't expose any Appian service without authentication, and on the post method I don't see any option where I can write an API-key or something similar, only the callbackurl. Is there any method where I can expose an Appian Web Api?

Hi All, As we checked in the particular KB article, there is an option called proxy host, port while configuring the webservices. Refer below article. KB-1306 How to integrate with web services requiring an HTTP proxy server - Appian Knowledge Base - Support - Appian Community However, in the latest version of Appian, while implementing with web Api integration, we do not have the option for passing the proxy host and proxy port. What is the best process to implement the HTTP proxy in web Api?

I have a scenario to clone application objects to create them as separate application and I couldn't find any api that can clone objects (under different application prefix) and set the object dependencies to newly created objects (uuids or object with new prefix). For example: Application has rule A_A, CDT 'A_B' and process model 'A C' where process model 'C' uses rule A & cdt B. I have to now create another application with prefix lets say 'X' and clone objects from A into it with rule X_A, CDT X_B and process model 'X C' and ensure that process model 'X C' now refers to X_A and X_B. All of this to happen in a plugin (servlet or smart service). Explored ApplicationService and AssociatedObjects and both of them don't offer any such methods.  Appreciate any help/suggestions.
