Limitations of Visual Workflows

While helpful, visual workflows aren’t without their challenges. A notable limitation is the "Deutsch limit", which restricts the display to about 50 visual elements on a screen . This can make managing very complex workflows tricky.

Other common issues include:

Handling Edge Cases: Complex scenarios may require custom coding, which visual tools alone might not support .
Performance Concerns: Code generated by visual tools may run slower than hand-written solutions and can be harder to optimize .
Version Control: Standard version control systems often struggle with visual formats .

When workflows demand advanced error handling or intricate business logic, visual tools might not be enough. Platforms like Laminar address this by offering a mix of visual design and coding options.

Being aware of these limitations helps teams choose the right tools for their needs. Carefully assessing the complexity of your integrations will guide whether a visual workflow approach is the best fit.

Code-Based Integration Development

Using code to build integrations remains a key approach for handling complex requirements. It offers unmatched control, making it a go-to option for companies like Uber, which relies heavily on custom code for real-time data processing.

Benefits of Custom Code

Custom coding brings a range of advantages for integration projects. For instance, Spotify uses custom-built services written in Java and Python to manage its massive user base of over 500 million people.

Benefit	Description	Real-World Example
Complete Control	Enables full flexibility for implementation and optimization	JP Morgan Chase's custom banking solutions for security compliance
Long-term Stability	Built using reliable programming languages and frameworks	Amazon's fine-tuned e-commerce platform
Code Ownership	Avoids recurring licensing fees by owning the code outright	Allbirds' custom Shopify integration for inventory management
Advanced Features	Handles complex logic and sophisticated data processing	Uber's real-time location tracking and routing system

Despite these strengths, custom code isn't without its challenges.

Challenges of Custom Code

While powerful, custom code comes with notable obstacles. A staggering 80% of companies report that integration issues are slowing their digital transformation efforts. On average, organizations juggle 130 SaaS applications .

"Integration Maintenance is the work done by your engineers to fix bugs, edge cases, and unexpected errors caused by varying response bodies from third-party API through the entire lifecycle of your product."
– Anthony Lagana, Product Marketing @ Merge

Here are the most common hurdles:

Technical Complexity:
Managing APIs and authentication methods requires expertise. Developers must also navigate challenges like rate limits, pagination, and unique customer test cases .
Resource Demands:
Custom code often involves long development cycles, a need for skilled engineers, and continuous updates to adapt to changing data .
Integration Risks:
Unexpected API responses, security vulnerabilities, and dependencies on external platforms can all disrupt functionality .

In regulated industries, custom code is often chosen for its control and precision. However, these drawbacks underscore the need to weigh control against resource demands when deciding between custom code and visual integration tools.
