How Data Moves Between n8n Nodes

This guide explains the basic process of how data moves between n8n nodes. One of the main strengths of n8n is its ability to move information automatically between different applications and services. Instead of manually copying information from one system to another, a workflow can retrieve data, process it and pass the result to another node for the next stage of the automation. Each node performs a specific task, while connections determine where the resulting data should go. This creates a flow of information through the workflow, allowing simple or complex business processes to be automated. For example, an n8n workflow could receive a new lead, process the lead information, send it to a CRM system and then notify the […]

How To Navigate n8n Interface & Canvas

This article will show you how to navigate n8n interface and Canvas. n8n provides a visual interface that makes it possible to build workflows by connecting different nodes together, while still giving developers the flexibility to add custom code and integrations when required. The interface is centred around the workflow canvas, where you create and organise your automations. The canvas allows you to add nodes, configure their settings and connect them together to determine how data should move through a workflow. For users who are new to workflow automation, understanding the n8n interface is an important first step before creating more advanced automations. Once you understand how the canvas, nodes and connections work, […]

How Data In n8n Is Structured: Items, JSON & Binary Data

This guide introduces the basic concepts of items, JSON and binary data in n8n and explains how they are used when information moves through a workflow. n8n workflows do more than simply connect applications; they also process and transfer the information produced by those applications. Understanding how n8n structures data is therefore important when building workflows, especially when information needs to be transformed or passed between multiple nodes. n8n workflows commonly work with structured information such as items and JSON data, while binary data can be used when workflows need to handle files or other non-text content. This structure allows information received from one application to be passed to another node for […]

How To Use Nodes, Connections & Executions

This article will show you how to use Nodes, connections and executions in your n8n workflows. n8n workflows are built around three important concepts: nodes, connections and executions. Understanding these concepts makes it easier to create, test and troubleshoot automated processes, nodes, connections and executions. A node represents an individual step in a workflow. Nodes can trigger workflows, retrieve information, transform data, send information to another application or perform other actions. Connections determine how the nodes interact with each other and establish the path that information follows through the workflow. An execution refers to a run of a workflow. When a workflow is triggered manually or automaticall […]

How To Configure Reverse DNS & PTR Record For A VPS

Reverse DNS (rDNS) is an important part of managing a VPS, particularly when the server is used for email or other services where the server’s identity needs to be verified. While standard DNS uses records such as A records to associate a hostname with an IP address, reverse DNS uses a Pointer (PTR) record to associate an IP address with a hostname. A correctly configured PTR record can help receiving mail servers verify where email originated and can reduce the likelihood of legitimate messages being rejected or treated as suspicious. Domains.co.za notes that reverse DNS is particularly important for VPS mail servers, and that a missing or incorrect PTR record can affect email delivery. This guide explains a PTR record, whe […]

How To Monitor Windows VPS Resource Usage

This article will show you how to monitor your Windows VPS Resource Usage. A Windows VPS provides a dedicated virtual server environment where applications, websites and other services can be installed and managed. As the server workload increases, monitoring CPU, memory, storage and network activity becomes crucial for maintaining consistent performance. Resource monitoring can help identify applications consuming excessive resources, storage capacity issues and unusual activity. It can also help you determine when your VPS may require additional resources. Windows includes several tools that can be used to monitor server resources. Task Manager provides a quick overview of CPU, memory, disk and network usage, while Resourc […]

How To Monitor Linux VPS CPU, RAM, Storage & Network Usage

Monitor Linux VPS is an important part of maintaining a reliable server. CPU, RAM, storage and network usage can provide useful insight into how your applications and services are performing and can help identify potential resource bottlenecks before they become serious problems. Domains.co.za Linux VPS Hosting provides guaranteed resources, KVM virtualisation and full root access, giving administrators greater control over the server environment. Unlike standard Web Hosting, where cPanel provides tools for monitoring account-level resources, Linux VPS resource monitoring is performed directly on the VPS operating system. This means you can use standard Linux command-line tools to monitor the server in real time. Regular mon […]

How To Add An SSH Public Key To A Linux VPS

Adding an SSH public key to your Linux VPS improves security by reducing the risk of password-based attacks such as brute-force attempts. It also simplifies server administration, particularly if you regularly connect to your VPS or automate deployment and maintenance tasks. Secure Shell (SSH) is the standard method of securely accessing and managing a Linux Virtual Private Server (VPS). While SSH supports password-based authentication, using SSH keys provides a more secure and convenient way to login to your server. SSH key authentication uses a pair of cryptographic keys (a private key stored securely on your computer and a public key installed on the VPS) to verify your identity without transmitting your password over the […]

How To Back Up And Restore A Linux VPS

This guide explains how to back up and restore a Linux VPS. Regular backups are one of the most important parts of managing a Linux Virtual Private Server (VPS). If you are hosting websites, databases, applications, or development environments, having a recent backup allows you to recover quickly from accidental file deletion, software failures, configuration errors, security incidents, or unsuccessful updates. A VPS backup creates a snapshot of your server that can be restored if something goes wrong. Keeping regular backups helps minimise downtime and reduces the risk of permanent data loss. It is recommended that you always create a backup before making significant changes to your server, such as installing new software, […]
