API Best Practices

In plain words: REST is like sending a postcard (lightweight, JSON-formatted, quick to read), while SOAP is like sending a registered, tamper-evident envelope with a legal contract inside (strictly typed, XML-only, highly regulated). Salesforce supports both to let you connect any external system. Salesforce integrations rely on communication protocols that determine how external applications talk to your CRM data. While modern architectures favor lightweight, mobile-ready interfaces, legacy enterprise architectures demand strict contracts and strict data governance. The two primary protocols fulfilling these needs are REST (Representational State Transfer) and SOAP (Simple Object Access Protocol) .

In plain words: Integration patterns are standard blueprints that dictate how Salesforce talks to other software. Instead of building custom connections from scratch every time, architects pick a proven pattern based on volume, timing (real-time vs. batch), and whether data needs to be copied or simply viewed. Connecting Salesforce to an enterprise landscape requires more than just making API calls. Choosing the wrong communication pattern can lead to hit governor limits, performance bottlenecks, and brittle point-to-point connections. Understanding the standard integration patterns allows you to build scalable, secure, and maintainable systems.
