Nintex Automation K2

Hello K2 Community,I'm currently migrating workflows from K2 BlackPearl 4.7 to K2 Five 5.8 and need guidance on updating a specific workflow pattern in K2 Designer.Current Implementation (BlackPearl 4.7):Our existing workflow uses the following pattern:Invokes a Code Reference Event to execute custom logic Loads the returned data into an HTML-formatted variable Passes that HTML variable to an Email Event for deliveryMigration Challenge:I'm new to both K2 BlackPearl and K2 Five, and I'm not sure how to replicate this pattern in K2 Five 5.8's Designer. Specifically:What's the recommended approach for Code Reference Events in K2 Five? Are there any breaking changes or differences in how data is handled between the two versions? What's the best practice for building dynamic HTML content in K2 Five before sending emails?I've attached the relevant workflow snippets from our BlackPearl implementation for reference.Thank you for any guidance!  

Hi,We are currently exploring options to secure our internal APIs, which are consumed through SmartObjects.Our objective is to ensure that we can reliably identify the user making a request following authentication, while maintaining a secure approach throughout.As part of a proof of concept, we have successfully configured service instances using PKCE, Microsoft Online, and Client Credentials resource types, with SmartObject methods connected to one of our API endpoints.The PKCE flow appears to be the most suitable option for interactive form-based scenarios. However, we encountered some challenges when testing workflow scenarios. Since K2 workflows execute under the K2 service account, we enabled the following option to allow the SmartObject to function within workflow steps:Cache OAuth token for service account for using SmartObjects in workflow steps What we observed is that the cached OAuth token associated with the service account appeared to correspond to the user who last refre

Chrome is deprecating client-side support for XSLT, including the XSLTProcessor JavaScript API and the XSLT processing instruction, which K2 uses in design time and runtime experiences. Chrome plans to remove this support starting with version 158, scheduled for release on November 17, 2026. Fix packs have been released for supported K2 versions (5.7), (5.8), (5.9), (5.9.1), and later versions. Nintex K2 Cloud Update 22 Fix Pack 16 is also available to ensure that K2 will continue to function after the deprecation.  The following fix packs are available for download for Nintex Automation K2 Nintex Automation K2 (5.9.1) FP 2 Nintex Automation K2 (5.9) FP 14 Nintex Automation K2 (5.8) FP 35 Nintex Automation K2 (5.7) FP 30We recommend installing the latest available fix pack as soon as possible. If you cannot do so before November 17, 2026, there are workarounds based on the browser (Chrome or Edge) to help extend functionality temporarily.Google Chrome BrowserShort Term (0–1 month): Ent

Hi all, I would like to ask about a configuration error that occurred after I changed the K2 database. The log is shown below: Error Number: 15151, State: 1, Class: 1614:28:17: >> AnalyzableAction.PopulateValidateAndExecute: End execute standard action: SourceCode.Install.Package.Actions.Database.GrantKeyControl: SQL - GrantKeyControl Service Account SCSSO, result: False...A blocking error has occurred and setup cannot continue. Please inspect the log file for details and select the 'Recover' option in Setup Manager after corrective action has been taken to complete the installation.Could anyone advise on a possible solution for this issue?

Hi, Where is the document for Migrating from EWS to Graph via the Wizard? In management - Features, you can click the Exchange Online feature and do Migrate, but where is the documentation on that to go from EWS to Graph? There is a document on doing it manually using “Lesser permission”, but where is the documentation for using this wizard?  Thanks

In the initial Setup Manager. I Clicked on the Full Installation and then once entering the License Key the setup manager got crashed.I am seeing the below logs in the event Viewer. Application: SourceCode.SetupManager.exeFramework Version: v4.0.30319Description: The process was terminated due to an unhandled exception.Exception Info: System.AccessViolationException   at <Module>.K2LicenseUtils.DecryptString(ATL.CStringT<wchar_t,ATL::StrTraitATL<wchar_t,ATL::ChTraitsCRT<wchar_t> > >*, ATL.CStringT<wchar_t,ATL::StrTraitATL<wchar_t,ATL::ChTraitsCRT<wchar_t> > >*, ATL.CStringT<wchar_t,ATL::StrTraitATL<wchar_t,ATL::ChTraitsCRT<wchar_t> > >*)   at SourceCode.Licensing.K2LicenseValidator.ValidateLicenseKeyV1(System.String, System.String)   at SourceCode.Licensing.K2LicenseValidator.ValidateLicenseKey(System.String, System.String)Exception Info: System.Exception   at SourceCode.Licensing.K2LicenseValidator.ValidateLicenseKey(System.S

Hi guys!I have upgraded to version 5.9. However, the forms and views cannot open. When I do some research it said, the version must be upgraded one by one (K2 Blackpearl 4.7 > K2 Five 5.6 or 5.7 > K2 Five 5.9).So I check the history, and it is sequence which is correct.   However error is still showing when I open the form. Why?: 

Hi, anyone know how to downgrade K2 five 5.9 to K2 five 5.6?Before this, the old version is K2 Blackpearl 4.7. Now I'm upgrading to K2 Five 5.9 version and I have countered issues where some forms and views cannot open. After doing some research, I just know that it cannot install directly to K2 Five 5.9. Below is from Nintex:“Upgrading Nintex K2 blackpearl (4.7) or Nintex K2 Five versions (5.0), (5.1), (5.2), (5.3), (5.4), and (5.5) to latest version of Nintex Automation is not supported.  You must upgrade from a previous version to at least Nintex K2 Five (5.6) or Nintex Automation (5.7) before upgrading to the latest version of Nintex Automation.”So how can I solve this problem? Should I downgrade the version or is there any solution to resolve this issue? If I need to downgrade the version, what is the proper way to downgrade the version? Should I just uninstall the version and go back to version K2 Five 5.6 or K2 Blackpearl?

Hi guys,Has anyone upgraded their K2 Five environment from an older version to the latest one? I recently upgraded mine from version 5.4 to 5.9, and some of the forms have been impacted as a result.How did you handle these issues? Did you recreate the affected forms or views, or is there another solution to resolve them without rebuilding everything?As you can see the picture below is the error because of this upgrading version:  

Hi guys, do you guys know where I can find the Workflow ID based on Process ID in K2 database? As you can see Process ID = 20295 and WorkflowID = 2493 (It is recorded in the current data)  

Hi, Anyone experienced this or able to advise:Upgraded to v5.9 and when users are loading the forms, they are getting the Windows “Sign in to access this site” message.IIS Runtime authentication is set to Windows Only (same as prior), but instead of the forms loading them are being prompted. If they enter their credentials, it loops back to the SIgn in box again. Any ideas?Thanks

Hi everyone. Is it compulsory to use EWS to interact with SmartAction? Because my company uses SMTP instead.

Hi guys, I do really need help regarding this problem. I couldn’t find K2 Setup Manager in Start Menu. Thus, I can’t enable SmartAction. Mine is version 5.9. Does anyone have same issue as mine??

Hi guys! I would like to ask if you guys know where I can find the record transaction of activities in workflow in K2 database? I want to do audit trail for overview of activities in the workflow.

Hi,I'd like to have a discussion about the section titled "Update the Service Account password after expiry" at the end of the documentation https://help.nintex.com/en-us/nintexautomation/icg/5.8/Content/Plan/Accounts.htm.I know that the password for the K2 service account can be changed using the K2 Setup Manager, but the wizard sometimes takes a long time to complete all its steps, and on top of that, re-applying the latest Fix Pack is another thing that needs to be done - even though changing the service account password seems so simple.I’d like to focus on the second method, which uses command-line parameters.Does anyone know of any other possible parameters for SourceCode.SetupManager.exe, or perhaps all of them?For example, I’m wondering if this method can also be used to change the password for the service account used for the IIS App Pools K2 and K2_net4, or can this just be changed directly in IIS? (I don't use a single account for everything)Another thing is that the instruct

Hello together,I have a problem with my K2 Smartobject. I have a SQL Database on another Server. When I configure the instance I use “static” authentification method. I connects to the server and no error message. Then when I try to use the method to get all the database entries. I get an error message. I think it uses a different conntext user. How can I use the right context SQL user? I’m also missing the methos for creating and updating a databaseI hope you can help me. Best regardsMatthias

What if you could hold a conversation with your process automation platform to quickly generate a purchase order request, rather than spending time hunting down vendor codes, cost centers, and product specs while working through revision after revision?In this proof-of-concept session, I enabled that capability with Nintex Automation K2 and Claude desktop. Ride along with me to learn more!When Anthropic released the Model Context Protocol (MCP) as an open standard for connecting AI assistants to external systems, we started thinking about what it would look like to wire it up to K2 Five. So, to test it out I opened a conversation with Claude and we started building. What followed was one of the more interesting projects I have done in a while, and I wanted to share it with the Nintex community. Example use-case flowWhat Is MCP and Why Does It Matter for K2?The Model Context Protocol is a standard that lets AI models like Claude call out to external tools and APIs in real time during a

Hello together,I have an a string which look like this “test01@test.com;test02@test.com;test03@test.com”. No I want to loop through the string and send a spearate email to each email address. I tried this several times, but it won’t work in K2 Workflows Engine with the loop. Can you suggest me how I can build that kind of loop and send emails out?My workflow looks like that.Best regardsMatthias

Hi everyone. This is for my project. The scenario is the e-form will send out to the user and user will response through email outlook. That response (eg. Approve/decline) will determine the next progress in the workflow. Is there any possibility that the workflow or K2 five able to do such scenario? If can how can I setup in the workflow to receive the answer from outlook so that it will proceed to the next step?I just heard about smartAction that able to solve my problem. But how can I configure that smartAction since I dont have it in the K2 management. This is a new feature for me, so a bit confuses.  

Hi, i created a custom control with Smart Object.i deployed and its working fine. now issue is. i want to iterate that smartobject in for loop in rule as in below image. but its not showing any message on button click.

Hi,I have a K2 list view which uses a list display for one of the column controls. The control is bound to a field called “AnswerID”, and uses a smartobject called “Answers”, which contains the answer ID and description. This all works and displays the answer description when the ID is present in the underlying list view smartobject dataset.We also want to provide a way to update this answer, so in the Add/Edit row I have a drop-down list which is populated by another smartobject: “QuestionAnswers”. This contains the list of possible Answer IDs given the current Question ID. The display value is looked up from the associated “Answers” smartobject and the ID field is the AnswerID. When a row enters edit mode, this drop-down is populated for the relevant question. This also works.Where I am running into an issue is when applying the changes to the edited row. It appears that the selected AnswerID is being populated into the underlying smartobject, but the list display control still shows

Hi everyone,I want  to learn Nintex K2. I have no prior knowledge of K2 or SharePoint.I have a few questions I hope the community can help me with:1. Is SharePoint knowledge required before learning K2, or can I go straight into K2 without it?2. What is the recommended learning path/roadmap for a complete K2 beginner? Specifically:   - Which Nintex University learning paths should I start with and in what order?   - Are there specific YouTube resources or playlists from the official Nintex channel that are worth following?   - Are there any other resources (docs, books, tutorials) that helped you when starting out?3. As a developer, are there any concepts or topics I should prioritize that are especially relevant to the technical/developer side of K2?4. What are the most common mistakes beginners make when starting with K2 that I should avoid?Any advice from people who have been through this journey would be very much appreciated. Thank you in advance!

Got a Choice Control with 5 items with multiple option selection enabled.The last option in the list is Other, when the user ticks that box, I want it to make a textarea become visible underneath, A advanced rule works if you only pick the Other box and it shows/hides the textarea accordingly.However, if the user picks another item and the Other option, then it doesn;t work. With Multiple data type, i did a message and it shows the value as Option1;Option2 etc etc. So i assumed I could you advanced rule to say if Choice CONTAINS the Other value, but it won’t work. Why doesn’t the advanced condition work? The Choice control has two items picked, so you would think I could that in an advanced condition to say if it contains Other then do something. Any ideas?
