Good afternoon all, We are seeing an issue with generating a PDF file from the HTML document (that was generated with 'HTML Doc from Template' Smart service).

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?

Hi , we are facing an issue with huge tomcat logs size after enabling the recieve email configuration in our project. in the tomcat  logs I see the following recurring errorERROR com.appiancorp.mdb.EmailHandlerBean - Error receiving message in EmailHandlerBean MDBjavax.mail.MessagingException: Message could not be sent;Caused by: com.appiancorp.messaging.ProcessRouteMissingException: APNX-1-8001-001: No Process Routing Information Provided: Needs one of DestinationEventPersistentID, DestinationProcessID, DestinationPMID, DestinationPMUUIDThis doesn't make much sense since the only process model UUID that I have receiving emails has been added to the custom properties file already. What could be the issue here?

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.

Nice to meet you, Appian community members! I'm looking for a no-code/low-code solution in order to properly develop corporate processes in my company. As I know from the recommendations of our colleagues, the Appian platform could be a wise choice for that purpose. My main question: is there any way to pair/integrate the Appian tool with other enterprise platforms, namely Camunda? Current use case: we need to integrate Camunda technology in a low-code solution for easier business process building.  Looking forward to your response

Hi,  We are defining the architecture in a new client and we are looking at the different options we have to communicate from Appian Cloud with the client's private network (and vice versa). Reviewing the documentation, it seams that the only methods of connectivity with Appian Cloud are VPN and AWS Private Link. Does anyone know if Appian supports a P2P link? Thanks!

Is it possible to generate a Word document with a dynamic summary of the document using native or plug-in functions? My need is to create a paragraph in the Word document for each item in a list. If there are many paragraphs, it would be useful for the user who will have access to this document to have a summary that shows the link and page for each dynamically inserted paragraph. I'm now using the DOCX From Dynamic Template smart service of the Advanced Document Templating plugin which allows me to dynamically generate paragraphs but I can't get the summary to update when the document is generated. So the summary remains empty. If I use the template with the summary already updated, the generation of the document fails because the logic of the list is on the dynamic construction of the paragraphs. Thanks

This is a "how does Appian do it?" questions.   I'm working on an Appian site that uses webContentfield to display an outside site inside of Appian (like an iFrame).   This outside site is using the credentials from SSO to log the user in.   We are pretty sure it is using the session to do that but I don't see anything that specifically sets that up.   We need to do this with another 3rd party and they are asking how the credentials are getting passed.   Does anyone know the magic of SSO that is happening in this situation?
