API - stands for Application Programming Interface and can be translated as programming interface. As the name suggests, an API allows foreign programmers to access selected functions. The interfaces serve as an access point for other software, so to speak. Via the API, programmes can communicate with each other, exchange data and pass commands.


Component - A component is a function that is displayed in the form of a tile in the Designer.

Connection - A flow connection connects flow components with each other. A flow connection always connects an output with an input of the respective flow component.

CSV - The file format CSV stands for Comma-separated values (more rarely Character-separated values) and describes the structure of a text file for storing or exchanging simply structured data. Tables or a list can be represented in CSV files.


Designer - The Designer provides a user interface to model and control workflows in the instances with the help of components. The Designer already includes a flow engine.


Flow Chain - A flow chain consists of at least two flow components that are connected to each other with at least one flow connection.

Flow Engine - A modelled flow instance is executed in a flow engine.

Flow Instance (Workflow) - A flow instance is a collection of individual flow chains and/or flow components that logically run together in a context.

Flow Message - A flow message is a data packet (usually a JSON object) that is transmitted via a flow connection.

Flow Template - A flow template is a template that can be imported into the Flow Designer.


HTTP - stands for "Hypertext Transfer Protocol" and regulates how data is transferred between two systems.

HTTPS - steht für „Hypertext Transfer Protocol“ und regelt, wie Daten zwischen zwei Systemen verschlüsselt Übertragen werden. Der Unterschied zwischen HTTP und HTTPS liegt darin, das HTTPS ein besonderes Transportprotokoll nutzt, welches die Übertragung mit SSL/TLS verschlüsseltThe difference between HTTP and HTTPS is that HTTPS uses a special transport protocol that encrypts the transmission with SSL/TLS.


Instance - An instance represents a functional unit that is concrete and self-contained. Templates can be used to create many identical instances.


JSON - JavaScript Object Notation (JSON) is the data exchange format that enables these transfers. JSON is popular among developers as a data format because of its human-readable text. This is easy to read, requires less code, and is processed faster.


Low Code - The term low code means developing software with little programming knowledge. This is done with the help of graphically designed building blocks that are connected to each other in order to represent a programme sequence.


Manager - The Exolink Manager is the customer area where all instances, subscriptions and permissions are managed.


Output - All data that has been processed can serve as output.


Role - A role is a group of permissions with which logins to accounts/flow instances/service subscriptions are authorised. (e.g. Owner, Admin, Auditor)


Subscription - A Service Subscription is a flat rate to receive support in the form of Mail/Chat/Screencast/etc.


Template - A template for a data and processing structure that is not, however, filled with values and can thus be used again and again.

Trigger - Trigger is an action that starts something. This action can be very diverse, but must be measurable. Example: If a folder becomes too full, this can serve as a trigger for a job to delete old files.


XML - The Extensible Markup Language, abbreviated XML. XML is a text-based data format similar to JSON. XML consists of so-called tags, which are placed between angle brackets '<' '>' and are nested in each other in order to be able to create a hierarchy. The advantage is its simplicity and widespread use. However, it also has the disadvantage that it requires more storage space than is absolutely necessary.


Workflow (Flow Instance) - A flow instance is a collection of individual flow chains and/or flow components that logically run together in a context.
