Is there a way to easily generate a JSON output from the form submitted? I am new in that specific space and would love an action or something that could easily summarise the form and captured information and generate a usable JSON. I need something that does that and appends the JSON file to something like an email action. I also want to try and avoid having to use SPO etc to store the file and then retrieve the file. SmartIQ and other such forms and workflow engines can do that natively, however Nintex does not appear to have something that I would consider a core easy win.Thanks.

I have an enquiry regarding the email issued from Nintex from a given tenant / organisation.Is it possible to (from a given form and workflow) reply to an email sent from Nintex in response to content received in order to start a new workflow process?I.e. A user fills in a form asking to have something sent to them (reports etc).Assigned task sends this request to a nominated user (or group). They can read the saved information and reply back with a text field. This text field is captured and as an action post the assigned task, send email with the ‘REPLY’ embedded.The Workflow ends.THEN the original user receives the response and then decides, no i wanted something else OR files a complaint or something.Can that user ‘reply’ to the email received (permitted a Reply TO) was added to that email which could then interact with Nintex Automation Cloud?

Hi Team,We have a requirement to trigger Nintex from a Salesforce Flow in order to generate a document with merge fields, tables, and related data.However, when creating the Flow in Salesforce (sandbox environment), we are unable to find any Nintex actions available.Could you please confirm if there is any additional setup required on the admin or configuration side to enable Nintex actions in Flow within a sandbox? If so, could you guide us through the necessary steps?Thank you.

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.

Fix packs will be released for supported K2 versions (5.7), (5.8), (5.9), (5.9.1), and later so that K2 will continue to function after the deprecation. The following fix pack is available for download for Nintex Automation K2 Nintex Automation K2 (5.9.1) Nintex Automation K2 (5.9)We recommend installing the latest available fix pack as soon as possible. If you cannot do so before November 17, 2026, the following workarounds, based on Chrome’s own mitigation options, can help extend functionality temporarily. Short Term (0–1 month): Enterprise Policy Controls  Enable XSLT through Chrome’s enterprise policy. Configure the policy dedicated to XSLT preservation via your Google Admin Console or Group P

Hello, I need to obtain all the field values from a task form and send it to an API.. Few times in the workflow.I was wondering if I could get an usable JSON form of the Task form?At least if I could move all of the controls inside a Repeater, will I be able to get useful JSON - the same way we used to get XML when using "Nintex for SharePoint" repeaters? Sample formand the cryptic output I get. The JSON variables have some random text appended. Thanks in advance.

Hello,I am using [mArchive] stored procedure to archive K2 Five database. Just want to know what kind of locks used in the stored procedure.Is it table level or row level?Can we run this stored procedure during business hours so that users can continue their work without any issues?What will be the impact on daily work in case tables/rows locked?Is there any measure how many rows can be archived in one go so that there should not be any impact on users?How much time generally it takes to complete execution, first time and there after?Thanks

Hi Folks! I am not sure I am describing this properly but since the of May update, when you approve a task, the task panel does not close automatically when you click off of it. You have to close it manually which reduces the efficiency a little bit. Has this been addressed? Has anyone else noticed this change?

Hi there Nintex Community,I have a trial tenant for Nintex Workflow Cloud.and used the Nintex Gallery JS-Insert installation steps to register the plugin in my Nintex Automation Cloud tenant using plugin hosted athttps://ashleypresalesfunctions.blob.core.windows.net/nac-plugins/js-insert.jsI was then able to drag the JS-Insert control onto my Nintex form start event form, however when I select the JS-Insert control I only see a single line element to enter the in the JS to Execute field as below:These posts indicate multiple lines of JS are possible.JS-Insert Functions to Execute | CommunityExamples of JS-Insert usage | CommunityIs this a limitation of the hosted plugin I am using at “https://ashleypresalesfunctions...”?I also downloaded the template js-insert.zip file and tried to “Add plugin” and select the downloded  js-insert.js file, but that generated an error “Failed to load the plugin definition”Does anyone know if this js-insert plugin supports multiple line JavaScript?

I have an external data variable that I’m using to populate a repeating section. In order for this to work properly, I need to name the repeating section form controls using the unique identifier names of the related external data variable columns. An example: External data variable column name “Lead (Email)” is unique identifier “Lead_Email”.External data variables don’t automatically display their columns’ unique identifiers, so I find myself guessing at the unique identifier names. Is there a way to view/display an external variable’s column’s unique identifier?

I’m coming from Foxtrot (“Nintex RPA LE”), where it’s easy to single-step through every action (there’s a little button in the lower left corner).  And it’s easy to inspect local variables, lists, etc. etc. (in the pane on the right).Q1: With “Debugger > Trace variables”, where can I INSPECT the variables?     <= The only way I’ve found is to add an explicit “View Variables” Advanced Command Q2: How can I “single step” through EVERYTHING (Advanced commands and Core Actions, Wizards and embedded Wizards and Global functions)?  <= The only way I’ve found is “Debugger > Do it”, then click a button to “pause”        I HAVEN’T found any way to automatically stop execution and each and every action :)

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

Exciting news in the Nintex camp today as we release the public beta of the MCP connector for Nintex Workflow.  If you're not familiar with the term Model Context Protocol (MCP), it's a standard that lets AI assistants connect to systems such as Nintex.It is a beautiful thing.  AI tools such as ChatGPT provide reasoning and thinking but to actually do things, they need access to tools.  Nintex is one of those tools and you already know how powerful Nintex is so we're providing these AI assistants with a lot of power!This blog shows you how to set up your MCP connector and then takes you through some examples of how you can interact with Nintex.  It's only the tip of the ice berg though so I'd love to see in the comments what you achieve with it.I've used Claude desktop as my example AI companion for all screenshots.  At time or writing we also support Copilot via VS code and we are actively releasing support for other companions. SetupThis is super simple.  All you need to do is to log

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?
