Extensibility

I'd like to send documents from our Appian environment to another system using that system's web service. It was easy to make this work with small documents whose contents I can easily stream in body of a single request. However, the web service will not accept request bodies longer than a few MB and some of the documents I need to send are much larger than that (up to several hundred MB). The web service offers endpoints that support sending the document in pieces so that I could, for example, send a 10 MB document with 10 sequential calls, each containing one of the 10 parts of the document. However, the web service documentation just provides examples in C# and Javascript, which we obviously cannot use here. Is there a way to split a document into parts? I've searched the cloud-supported plugins and don't see anything like this.

I'm trying to expose a view from the Appian DB via a Web API.  The Web API requires a Data Store Entity Constant. So I try to create a constant with a Data Store Entity type, but I need a Data Store Entity created with the View Data Type. I create the view data type without issue and add it to the Data Store but it will not save and publish (I get a 'Appian.vwMyView' is not of type 'BASE TABLE' (APNX-1-4178-000) error). Also I do not want the view created as a table as it is already created in my DB as a View. How would I add an existing view into a Data Store? 

I Have an integration that is calling an outside system and when I try to call the connexted System I need to get a GRANT TOKEN, I know I can display a link to get this token, but is there another way to get this token, perhaps on a process model? or just calling it via a rule

Hi, I'm trying to integrate docker container packaged mail server with Appian application by updating custom.properties and password.properties. SMTP mail server currently integrated with Slack and works as expected(i.e. receiving slack notifications) when testing it separately using "curl" from CLI. However, Trying to test SMTP mail server integration from Appian thru process model - Send Email Smart Serrice node. I could not receive any output / email and no error messages on docker log and Tomcat logs. We've already turned on below DEBUG settings, log4j.logger.com.appiancorp.process.runtime.activities.SendEmailActivity=DEBUG  log4j.logger.com.appiancorp.ap2.mail=DEBUG It seems Appian is not communicating with SMTP mail server as we could not see any entries on docker logs. Process Model Send Email smart service status is “unattended”, this has been initiated as per tomcat logs and no error messages as shown below. 2021-08-05 14:58:41,403 [Appian Wo

Hello -  We are trying to use the Poll Email from Microsoft Exchange EWS API Plugin to retrieve emails from the office 365 mailbox . Our Mailbox is on cloud and we have to connect to the EWS service URL via a proxy . So we need to set the proxy flag as yes while called this plugin . The issue is when we setup the proxy flag as Yes . The plugin is asking for proxyUsername and proxyPassword . Our server proxies do not authenticate so we don't have these credentials .  We are trying to pass them as null on the third party credential screen but the plugin keep complaining with the error " Required field proxyUsername does not exist in SCS " . It looks like when we add these fields on the third party credential screen , the key value changes to lower case but the plugin is looking for parameter "proxyUsername" . Has anyone else tried to pass the proxy details to this plugin ?

I have an API response that has special characters in the attribute keys. Due to which, the sync fails when I integrated the API response to site records. Here is the API -  https://data.cityofnewyork.us/resource/5kqf-fg3n.json? Response has the following attributes in the body that Appian complains due to special characters ":@computed_region_efsh_h5xi":"24670",":@computed_region_f5dn_yrer":"41",":@computed_region_yeji_bk3q":"3",":@computed_region_92fq_4b7q":"24",":@computed_region_sbqj_enih":"61" How do I remove those attributes as those are anyway insignificant for the application. Please suggest all the possible ways a) Can we do that in API integration call itself, by handing the API response and removing unwanted JSON attributes. b) In the Records and data source sync, ignore certain fields Here are the screenshots of the API response

I am working on an integration for an application using Calendly. The integration works as intended, but they also have documentation about webhooks that allow information to be pushed to an endpoint as an event is scheduled or updated. I want to create a webAPI that runs a process model when an event is created in Calendly that will pull the data and log that information in Appian. Is this type of configuration possible within Appian and does anyone know how you would do that?

Hi! I'm working on an integration to bring documents to Google Cloud Storage via plug-in, upload file integration works fine, But it takes the document to the Google Cloud storage without the extension that is without any content as shown in the image below. To display the documents stored in google Storage, I use the get signed url integration and web content component where I can view the document if you have a type in google storage, but It will be downloaded a file without an extension instead of viewing the content. That is the file downloaded in downloads on my PC. You can see is a file without extension. Any ideas to edit the request and be able to send the extension to google storage?
