Release R26-6 #
Available from 16th June 2026
Highlights #
Connectors – only show Parameters and Methods for selected Authentication Type
Some Library Connectors have multiple Authentication Types defined on them and may require different Parameters to be entered, depending on which is chosen. Before this change, all Parameters would always be displayed, which could be confusing.
This update enables the interface to show only the fields that are relevant to the selected Authentication Type where they’ve been configured on the Connector.
Connector Methods can also be tied to a particular Authentication Type as some external systems’ APIs may make different endpoints available depending on how you authenticate with it.
Connectors > Settings/Edit Connector page – change Required attribute of Custom Fields
For both Template Connectors and Account Connectors, you’re now able to change the “Required” attribute of Custom Fields on the Settings/Edit Connector page so you can decide which are needed and which are optional:

Custom Connectors – performance enhancements for “Test Release” option
When building a Custom Connector, you have the option to install a “Test Release” into an Account so that you can try out your changes before putting them live on the Connector. Before this update, the Test Release feature could take 10 seconds or longer when working with a large Connector, but now completes within a few seconds.
Cyclr API – endpoints added to work with MCP Servers
You can now create, update and manage MCP Servers through Cyclr’s API. This includes adding and removing Connector Methods for individual MCP Servers.
See MCP Servers API endpoints for more details.
Cyclr Interface – consolidated Help options
We’ve combined several links and buttons relating to Help and Documentation, as well as logging Support Requests with the Cyclr Helpdesk, that were shown in various places within Cyclr’s interface into a single location, to make them easier to find.
The “Help” and “Resources” options are now shown in the top right of the interface:

MCP Servers – now support Custom Object Method Categories and Custom Fields
When selecting Connector Methods for use in an Account-level MCP Server (not an MCP Server Template within your Console), you can now select Methods that are within Custom Object Method Categories.
Custom Fields on Methods are also available for use through MCP Servers.
MCP Servers – now support Hint Annotations on Tools
To help a Large Language Model (LLM) understand how the Tools (the Connector Methods) available in one of your Cyclr MCP Servers can be used, you can now set Hints on them.
Improvements #
Builder > Event Trigger’s “Webhook” Step – no longer creates empty Fields
Previously, it was possible for invalid Fields to be created on an Event Trigger’s “Webhook” Step when invalid JSON was provided, causing the Step Setup popup to fail to open.
Connector Authentication – OAuth popup wasn’t always displayed
Resolved an issue where a popup might not be displayed when attempting to authenticate a Connector that implemented OAuth.
Connectors – “Object Name” fields of Custom Object Method Categories now Required
After installing a Connector with a Custom Object Method Category, if you attempt to copy one of those Method Categories, you now cannot proceed in the Copy popup without specifying a value for any Object Name fields shown, ensuring a valid new Method Category is created.
Connectors > Settings/Edit Connector page – corrected OAuth notification
Resolved a situation where a “Please update your authentication details” notification was shown in the bottom left of the Settings/Edit Connector page for Connectors using OAuth, even though the Connector was already authenticated.
Console > Account Management – improved deletion of Accounts
Deleting large Accounts could occasionally fail due to the volumes of data being removed so how they are being deleted has been improved.
Console > Account Management – searching now checks Description fields
When searching across Accounts from the Console’s Account Management page, the Name, External ID and now Description fields are all examined. The result of this is that Accounts’ Description properties can now be used to store useful information you and your team can search for.
Console > Connectors > Application Connector Library – resolved problem saving changes on “Settings” tab
Resolved an error when attempting to save changes to fields on the “Settings” tab within the Console’s Connectors > Application Connector Library. This was preventing updates to Partner-level values.
Console > Template Library – resolved error when deleting Template Release
Previously, deleting a Template Release could result in an error and the delete failing due to some unneeded internal references which have since been resolved.
Cycle Execution – Decision Step behaviour
A change to the behaviour of Decision Steps was introduced in the previous Release (R26-5). That was promptly reverted on all Cyclr Instances shortly after being identified so the original behaviour was restored.
Cycle Execution > Scripts – prevented runaway Regex execution
Ensured JavaScript code containing regular expressions cannot runaway, using up resources, by preventing it from executing beyond the existing Script Timeout.
Cyclr Interface – performance improvement when listing Transactions
Obtained a small performance increase when viewing a list of Transactions within Cyclr’s interface.
Cyclr Interface > Search – improvements to how it’s triggered
When viewing a list of items – such as Accounts, Connectors and Transactions – the Search box at the top automatically searches after you have entered text and paused. Changes have been made to prevent it performing a search twice if you press the Enter key, and also to ignore key presses such as the cursor keys from triggering it.
Cyclr Interface > Sign In – correctly redirecting after signing back in
When your Cyclr web browser session expires, you are taken back to the Sign In page. After signing back in again, you are now correctly taken back to the page you were viewing, instead of to your Console Dashboard or an Account’s Cycle list page.
Embedding > ORBIT – resolved loading issue
Resolved a situation where after obtaining an ORBIT URL, navigating to that URL could sometimes display an error, instead of the ORBIT interface.
Private Cyclr Instances > Admin Area > System Log – reduced UpdateWebhookJob failure entries
For partners with a Private Cyclr Instance, when viewing the Admin Area’s System Log, if an installed Connector that’s configured to automatically renew Webhook subscriptions with its external system fails, the System Log would fill up with entries for it. That’s now been reduced to a single error being logged every 3 hours.
Private Cyclr Instances > Partner Management – improved deletion of Partner Consoles
Deleting large Partner Consoles could occasionally fail due to the volumes of data being removed so how they are being deleted has been improved.
Transactions/Builder > Step Data popups – resolved Raw tab showing content
When viewing a Transaction or a Step Data, a Step Warning or a Step Error popup, the “Raw” tab wasn’t immediately showing its content and required a click before it would be displayed.
Transactions/Request data – improved how sensitive values are identified and redacted
Improvements have been made to how sensitive data (e.g. passwords and access tokens) is identified to be redacted from requests when viewing Transactions or executing calls.
Webhook Processing – improved reliability when under heavy load
In situations where the internal webhook queueing system was temporarily unavailable – perhaps due to very high load on a Cyclr Instance – requests to Webhook Steps could be lost. This changes that so that the system will retry writing the request to the queue for a period of 30 seconds, giving the system time to recover.
