OpenCelium 5.1 – Work More Intelligently in the Workflow Editor

With OpenCelium 5.1, we are releasing the next update to our integration platform shortly after the major 5.0 release.

While OpenCelium 5.0 took a major step forward in terms of functionality and visual design with its new workflow editor and completely redesigned user interface, version 5.1 focuses primarily on making work with workflows even more efficient, clearer, and more user-friendly.

Four new features take center stage:

This adds further features to the workflow editor that are familiar from modern development environments and offer significant added value, particularly for more complex integrations.

In addition to these new features, OpenCelium 5.1 includes numerous other improvements in the areas of user management, connector management, user interface, system configuration, and usability.

An Overview of the New Features – OpenCelium 5.1 Release

A typical example:
A workflow uses an IF statement to check whether a specific condition is met. Depending on the result, several API methods must then be executed.

Without a way to merge the two paths again, the shared sequence had to be partially defined on both sides of the IF. Alternatively, a `continue` statement could be used, which also resulted in a separate sequence. This not only led to additional configurations but also to redundant workflow steps, making more complex workflows unnecessarily difficult to read.

With the new Joint Element, workflow paths can now be merged again. This allows a common sequence to be defined once after an IF statement and then used by multiple paths.

This reduces:

• Redundant configurations
• Duplicate API methods
• Unnecessary workflow steps
• Maintenance effort

At the same time, workflows become clearer and easier to follow. The Joint Element is therefore an important tool for optimizing workflow structure, particularly for more complex integrations.

Debugger Mode for the Test Run

In debugger mode, the execution of the workflow is intentionally slowed down in the user interface. This allows the user to better follow the process step by step. The user can press ” Pause ” at any time.

Afterward, the data processed up to that point can be reviewed and analyzed. This makes it much easier to determine:

• which workflow step is currently being executed
• which API method was called
• which data has been processed so far
• how the data changes within the workflow

This offers a significant advantage, particularly when developing and debugging complex workflows.

Debugger or Live Mode—Switch Between Them at Any Time

The debugger does not have to be used throughout the entire test run. The user can switch between debugger mode and live mode at any time.

If the debugger is no longer needed, you can simply switch to live mode, and the test run will be displayed at normal speed again.

Important: The debugger currently only slows down the display

In the first phase of implementation, the debugger intentionally operates at the UI level. This means that the actual interface is not paused or slowed down on the backend.

While the test run appears to run more slowly in the user interface, the actual execution in the backend continues at full speed. In this version, the debugger is therefore primarily intended to help users better track and analyze the flow of the interface in the UI.

Undo & Redo for the Workflow Editor

Features that are standard in modern editors are now also available in OpenCelium: Undo and Redo. When creating complex workflows, many changes are made in quick succession. It’s easy to accidentally move, delete, or modify an element in the process.

With OpenCelium 5.1, such actions can now be easily undone. The Undo function allows you to undo the last change. The Redo function allows you to restore an action that was previously undone. This makes experimenting with workflows much safer. Users can try out changes without worrying about permanently losing a previous state.

Change History – An Overview of Every Change

Comment Boxes – Comments Directly in the Workflow

Improved User Management

User management has been expanded and now offers additional options for administrators. When logging in, users can now use either their username or their email address.

Users can now also be updated without having to re-enter a password. In addition, the ability to directly edit and update user groups has been integrated. This makes the administration of users and groups significantly more convenient.

Advanced Connector Management

The connector list has also been expanded. It now additionally displays the “Modified At” and “Modified By” information. This makes it immediately clear when a connector was last modified and which user made the change.

In addition, the tables in the user interface have been improved. Column widths can now be adjusted individually. This feature is available, for example, in the connector list and allows you to customize the display to suit your needs.

Improved Invoker Management

OpenCelium 5.1 also introduced the ability to add Invokers directly through the user interface. Editing existing Invokers is not yet possible directly through the UI.

To make changes to an existing Invoker, you must currently download it, edit it locally, and then upload it back to OpenCelium. Directly editing existing Invokers via the user interface is therefore a logical next step for future versions.

In addition, validation for invoker names has been integrated to detect invalid or problematic names as soon as they are entered.

System Settings and Customization

The System Settings have also been expanded. The configured theme and logo are now saved in the System Settings.

In addition, the system language selected by the user is saved in the user details. This ensures that personal settings are retained even when the user logs in again.

Image management has also been improved. Images for connectors and logos can now be cropped directly within the interface.

Quick Access to the Documentation

To provide even faster access to the OpenCelium documentation, a documentation icon has also been added to the header navigation.

This makes the documentation accessible directly from the user interface, without having to leave OpenCelium and open the documentation page separately.

OpenCelium 5.1 – The Workflow Becomes a Development Tool

With OpenCelium 5.1, we are consistently building on the new workflow approach introduced in version 5.0. The Joint feature reduces unnecessary redundancies and makes complex processes easier to understand. Debugger mode gives developers better insight into the progress of a test run. Undo/Redo and Change History provide greater reliability in day-to-day work. And with the Comment Boxes, the workflow itself becomes a space for documentation and collaboration.

Together with the numerous improvements in user management, connector and invoker management, and the user interface, OpenCelium 5.1 thus becomes an even more user-friendly tool for developing and managing modern API integrations.

Bug Fixes and Improvements

In addition to the numerous new features, OpenCelium 5.0 naturally also includes many bug fixes, performance optimizations, and technical improvements. A complete overview of all changes is provided in the changelog.
