Hello Team, I have created a Web API that triggers a process model. To consume this API, I created an integration object in Appian using the Web API URL. When I test the integration, it returns a 200 (OK) status code, but the process model is not getting triggered. After checking the response, I found that the integration is being redirected to the login page, and because the login page loads successfully, the response status is returned as 200. Could you please suggest the correct approach for implementing the integration on top of the Web API? Do I need to configure authentication differently or use another integration method to avoid the login page redirection?

My use case is I have a large PDF that is essentially a bunch of smaller PDFs stitched together. Each smaller PDF has a dynamic number of pages, and they’re split by a separator page, so a human can tell when an individual document starts. I know there’s a PDF Tools plug in, but it doesn’t seem like there’s functionality to split by a separator page or something similar - it’s all by a specified page range or by number of pages in a document. The best thing I can think of right now is to use AI or something to find out where the separator pages are, the page ranges of the individual documents are, and loop through the large document until the end, but that sounds like it might be complicated and I’m wondering if there’s a simpler solution? Thank you in advance!

Hi I have a requirement where I need to invoke an asynchronous API that returns a jobId in the response. After a certain wait time, I need to call a second API to check the status of the job by passing the jobId received from the first API. This status API should continue to be invoked at regular intervals until the job completes successfully. All of these steps must be completed before the form is submitted, as activity chaining needs to be maintained. Our current plan is to use a Start Process smart service to initiate the asynchronous operation and capture the process ID. I can then use Query Process Analytics at configurable refresh intervals to monitor the process status until the second API returns a successful response. Once the process completes, I can retrieve the results and display them to the user in a grid. Is there any better approach than this /any drawback in this approach. Anyone had similar requirement? Please sugget.

I'm using the MS Word 2007 Doc from Template in that smart service, but when the document is uploaded, it still replaces a few value tags even though the replacement values are already present.

Environment: Appian Community Edition — Site "W1423AIS Acme IT"Data Source affected: W0380 Data Source (MariaDB)Description:I am experiencing errors indicating that multiple tables are missing from my "W0380" data source, which I did not delete or modify manually.Errors observed so far: On the "W0380AS Vehicle" record type: "The configured database table is invalid. The AS_VEHICLE table does not exist in the configured data source. Change the database table to continue." Key details: I log into this environment regularly; my last login before noticing this issue was about one week prior.I did not perform any manual deletions, renames, or schema changes on these tables.The issue appears to affect more than one table within the same data source (W0380), suggesting a possible environment-wide database issue rather than an isolated table problem. Request:Please investigate whether the underlying database for this Community Edition environment w

We are using a DocuSign integration configured and tested successfully in the development environment with a DocuSign developer account. However, we are encountering issues during the authorization phase when using the authorization link. The authorization flow redirects correctly to DocuSign, and the login page is displayed, allowing the user to log in successfully. However, after the login, the system does not return the authorization token to the application as expected. By checking the application logs, we can see the following error during the OAuth callback processing. This error appears multiple times; below is one example: 2026-04-21 05:57:39,619 [http-nio-8080-exec-794] ERROR com.appiancorp.connectedsystems.http.oauth.OAuthServlet - Error processing request to Appian OAuth callback URL. com.appiancorp.suiteapi.common.exceptions.AppianException: Failed to decrypt.

We are using Rich Text plugin(Vuram) in our application and facing multiple issues some of them are - Copy the data in specific format and paste that in the editor. This does not maintain the formatting but disturbs the copied formatting - Generating some extra metadata within HTML tags causing failure in the document generation - Nested list items is not maintained too What are the options we have available to avoid such issues as the data formatting while copy paste or manual is prime requirement with the proper HTML generated by the plugin.

Hi, we are using the function a!sapInvoke to integrate with SAP throught RFC. Weeks ago, the integration worked  and we received the results expected. For development requirements, external system add some parameters and change the lenght of some text fields (from 20 to 25). After those changes, we receive errors on specific fields, but the return message gives a value that doesn't match the one sent. So, we check with external system and the problem is on all fields. For example, if we pass the parameter of the below images, external system receive as key1 the value "ABC/AAA/456789001/20ABC". It seems it takes the first 20th char and then take the others from key2. ICould you help us to understand the nature of the problem, please? Thanks in advance. Regards

I am looking for some guidance on generating large PDF documents in Appian.We have an existing site page that displays more than 13,000 records. As part of an export feature, we retrieve the data, generate XML content, generate a word document and then convert it to PDF (using Advanced Document Templating plugin). Currently, the export process retrieves around 3,000 records. Each record contains several large text fields (around 5 - 6 columns) so the overall amount of content is quite large. The word document is generated successfully and is about 768 KB in size and has approximately 5 million characters. The issue occurs during the word to PDF conversion. The conversion starts, but it appears to consume significant resources and causes the environment to become unavailable.  My questions are: 1. Are there any known character limits for Word to PDF conversion plugin?2. Are there any alternative plugins or approaches that are better suited for large documents? I understand
