A comparative analysis of Salesforce Flow and Apex Trigger
Introduction
As we all know, Salesforce has a wide variety of capabilities that make it one of the best platforms for managing customer relationships and increasing sales. Salesforce is really hard to beat in terms of that. But to truly use the full potential of this platform, we need to understand its automation power. In general automation has a crucial role in today's business world because it has a really big impact on productivity and effectiveness. So it is important to get familiar with automation tools offered by Salesforce. There are four main automation tools and each of them has a specific purpose:
- Workflow Rules
- Process Builder
- Flow
- Apex Trigger
It is essential to point out that Workflow Rules and Process Builder are still accessible, but it is no longer possible to generate new ones. Salesforce is actively currently migrating to Flow, as support for these tools is scheduled to be discontinued in the future. That is why Flow and Apex Triggers are the most important tools to understand and learn if we are speaking about automation solutions in Salesforce.
One common issue for Salesforce users is determining whether to use Apex Trigger and when to rely on Salesforce Flow. This topic can be confusing. That is why this article exists. We are going to answer the main question: “What is the difference between Salesforce Flow and Apex Trigger and when should we use each of them?”.
Salesforce Flow - what is that?
Salesforce Flow is a powerful automation tool that allows users to automate complex business processes without requiring any coding skills. Some people usually call it “Salesforce’s favorite child”. The reason for that is this tool is smarter and faster than its siblings Workflow Rules or Process Builder and since Salesforce wants to focus development on a modern, low-code automation solution in Flow Builder, the previous features will soon be a thing of the past. It is also more powerful and useful for setting up processes that need more complex logic branches. It can be used as a background process, but also to create wizard-style screens that guide users through sequences of activities and automatically update data throughout the process.

As you can see, there are several types of flows within Salesforce Flow, each tailored to specific use cases. Let’s quickly describe some of the most common used by Salesforce users:
- Screen Flows guide users through a series of screens, allowing them to provide input or make selections.
- Record-Triggered Flows activate automatically when a record is created or updated, making them ideal for real-time automation.
- Autolaunched Flows operate in the background without user interaction, making them perfect for batch processes.
- Platform Event-Triggered Flows respond to specific events occurring within the Salesforce environment, providing a robust mechanism for automation.
If you want to get hands-on experience in building Flows and try out different Flow types but you are not sure how to start, this trail can be very helpful. You also can use official Salesforce documentation that certainly can help you dive deeper into Flow's functionalities.
Apex Trigger - what is that?
To understand what Apex trigger is, let’s start from Apex in general. It is a strongly typed and object-oriented programming language available on the Salesforce platform. A lot of people agree that the syntax of Apex has similarities to Java syntax, so for those who know Java understanding of Apex is not a big deal. The possibilities of using Apex for Salesforce are huge. It takes a little bit of code work to use it, but the capabilities it provides are absolutely amazing. That is why Apex is the one that supports us and has our backs when Salesforce Flow just isn’t enough.
Salesforce Apex Trigger is a procedure in a database that is automatically invoked whenever a specific event occurs. There are two types of Triggers in Salesforce: Before Triggers and After Triggers, and they execute actions before or after the following types of operations: insert, update, delete, merge, upsert and undelete. Before triggers are used to update or validate record values before they are saved to the database. After Triggers, on the other hand, are used to access field values that are set by the system and to affect changes in other records. The flexibility allows organizations to implement complex logic that can’t easily be accomplished through declarative tools.
Below you can look at the syntax of Apex Trigger and two simple examples of its use.
You can find more detailed information about Apex Triggers in the following Apex Developer Guide. However, the best way to get more familiar with its use is to code yourself. If you are not sure how to start, try out these trailheads: Apex Triggers and Apex Testing.
Comparing Salesforce Flow and Apex Trigger
The primary strength of Salesforce Flow lies in its accessibility. As a declarative tool, it allows Salesforce users to create and manage workflows without delving into complex code. It also has an understandable interface that visualizes processes of the flow creation pretty easily. It is ideal for automating tasks and processes, such as updating records based on user input, sending notifications or emails upon specific triggers or creating guided workflows for data entry.
However, it does have limitations. Flows may struggle with intricate business logic and multi-step processes. Even though flows can be built quickly and easily modified as business requirements evolve, complex business logic that requires intricate decision-making may challenge its capabilities. Additionally, performance issues may arise when handling large volumes of records, particularly in bulk processing scenarios.
The primary advantage of Apex Trigger lies in its customization potential. They are capable of achieving better performance, particularly for intricate logic or bulk operations, due to their quicker execution and increased control over transactions like Flow may not offer. Whether it’s enforcing complex validation rules, manipulating data across multiple objects, or managing high-volume transactions, Apex Trigger can handle it all.
When it comes to choosing between Salesforce Flow and Apex Trigger, several factors should be considered. The choice usually relies on the project's particular needs, the level of complexity in automation, the team's expertise, and the need for maintainability and scalability. Salesforce Flow excels in its ease of use and availability, making it perfect for organizations that aim to enable non-technical users to develop. Nevertheless, as the needed automations become more intricate, companies could be limited by Flow's capabilities. On the other hand, Apex Trigger offers flexibility and performance, especially for complex scenarios involving multiple objects or advanced business logic. Nevertheless, this power comes at the cost of requiring specialized programming skills and greater maintenance efforts.
Conclusion
In summary, Salesforce Flow and Apex Trigger are both amazing automation tools that provide different needs and scenarios. In the end, it's important to find the right balance and ensure that whichever method you choose, aligns with your team's practices and the long-term maintainability of your Salesforce org.
