Here are the core concepts and terminology that you would need to know to use Oloid Workflow.


Flow is an automated process built by users that can integrate multiple applications. Each flow comprises of triggers and actions that are carried out when a trigger event is picked up. When flows are started, they run automatically in the background to look for trigger events and carry out actions. When stopped, they cease to look for trigger events.

A Flow is represented as a tab within the editor workspace. A Flow is a single set of connected nodes. So, a flow (tab) can contain multiple flows (sets of connected nodes).


For a flow to communicate with application via action and trigger nodes, it has to be authorized to interact by applications. This authorization is referred to as an account. Account is never tied to a flow one-to-one, instead a single account can be used by multiple flows.


A Node is the basic building block of a flow. A Node is triggered by either receiving a message from the previous node in a flow, or by waiting for some external event, such as an incoming HTTP request or a timer. They process that message, or event, and then may send a message to the next nodes in the flow. A node can have at most one input port and as many output ports as it requires.

There are 3 types of Nodes

  1. Trigger - Trigger determines what event to listen to execute the actions described in a flow. Trigger events can be set off in applications (e.g., ProWatch) when a certain event happens (“Door forced open” alarm is generated), or according to a schedule (fires at a certain time or interval). Depending on the available API, flow can receive trigger events in real-time, or check for the occurrence of an event periodically by polling the application.

  2. Action - Action is executed every time the trigger event occurs. Flows are required to have at least one action. For example, we can create a ticket in ServiceNow for the ProWatch “Door Forced Open” alarm.

  3. System - System nodes are set of nodes that are the non-application specific nodes. These nodes provide utilities to manage flows. The most useful ones are inject, debug, function & switch nodes.


Each time there is a trigger event, the actions in the flow are executed. The execution record of all nodes in the flow is called a job. Jobs can be successful (when actions are executed successfully), or have errors (when an action results in an error). When an error is encountered, subsequent actions are not executed.
