Hi guys, we have the requirement to start an Appian process via API from an external system and redirect the user to the url of the first task of that process. I tried to achieve this in the following way. We created a process model and activity-chained the first user input task with the start node. Then we created a POST api and start the process with a!startProcess and we valued the onSuccess parameter of that rule like this: a!httpResponse( statusCode: 200, headers: { a!httpHeader(name: "Content-Type", value: "application/json") }, body: a!toJson({ taskUrl: a!urlfortask( index(rule!LM_getTaskDetailsByPid( pid: index(index(fv!processInfo, "pp", null), "id", null) ), "taskId", null) ) }) ) where rule!LM_getTaskDetailsByPid is a rule that, given a process id, retrieves the id of the active task of the process in the taskId component using a task report and query analytics. Unfortunately we noticed that sometimes this fail

Hi all, I'm trying to finalize the integration approach for Appian cloud with AWS RDS Sql server. It seems there are two options available. 1. Private Link 2. Ip Sec Site to site VPN connection (VPN Tunnel). (Also I understand Appian cloud does not support VPC peering, however I could not find the reason behind this. ) Private link cons: https://docs.appian.com/suite/help/21.2/Access_Customer_VPC_using_AWS_PrivateLink.html "RDS is not officially supported behind a Network Load Balancer; therefore, if you would like to connect to RDS environments over AWS PrivateLink, you will have to employ one of many workarounds to create a VPC endpoint service in their VPC." It seems Ip Sec VPN not required to update the DNS of the RDS instance. Still bit confused if there any other advantages of using Privatelink than VPN tunnel? Could you please enlighten me on this? Thanks.

Hi Team, I have a requirement of calling different integrations in one PM node depending on few conditions. The response of all integrations are saved as a JSON file and usage of integration is "Modifies Data". Call integration smart service does not work as it does not have the privilege of setting up integration depending on conditions. Also calling integrations in script task/ER using rule! does not work as usage of integration is "Modifies Data".  Do we have any other plugin or smart service to fulfill my requirement?

Hi Appian folks, I was trying to go through Appian documentation and academy for creating a custom function plug-in.

Hi, Is there a way to establish CI/CD with azure devops instead of jenkins? Please guide on the same.

We have exposed Appian WebAPI to external and when it's being invoked like 1000 times in a bulk load process, and the linked Process Model itself just writes to 4 Record Types in Appian. But what is being observed is that, the Process instances are getting stuck at various nodes (Sometimes in XOR Node/ Some times on query Record) and on an average we are seeing 50 instances getting stuck out of 1000 being invoked. But if we only have 100 API calls at a time, then this isn't an issue. Any experience or suggestions.
