Variables, Data Types & Operators What Are Variables in Apex? A variable is a container used to store data that your program can use or change. Simple Explanation Variables are like labeled boxes where you store information. Common Data Types in Apex Apex supports primitive data types similar to Java....
What Is Salesforce Architecture? Salesforce is built on a multi-tenant cloud architecture.This means many companies use the same Salesforce platform, but each company’s data is securely separated. Real-Life Example (Easy to Remember) Think of Salesforce like a shopping mall: Mall = Salesforce platform Individual shops = Salesforce Orgs Security shutters...
Salesforce Flow is Salesforce’s main declarative automation tool. It lets you build complex business processes (create/update records, send emails, call Apex, show screens, run in the background or on a schedule) without writing code. It is the recommended replacement for Workflow Rules and Process Builder. Types of Flows Record-Triggered Flow...
Modern integrations aren’t just about connecting systems anymore — they’re about moving data and events reliably across multiple clouds and environments.The secret? A few tried-and-true middleware patterns (like pub/sub, request–reply, sagas, and streaming) combined with smart error routing strategies (retries, DLQs, compensations). Here’s a practical, field-tested guide to understanding these...
Salesforce webhooks are at the heart of modern, two-way integrations between Salesforce and external systems. Instead of simple one-way data syncs, your org can now have real-time conversations: external services notify Salesforce instantly, and Salesforce can call back out to complete the loop. Inbound: External apps send events into Salesforce...
OAuth 2.0 isn’t a single mechanism — it’s a toolbox of flows, each designed for different application types and security needs. The right choice depends on where your app runs and what secrets it can safely store. Here’s a clear, practical guide to the four most common flows you’ll encounter:Authorization...
A strong API contract makes integrations peacefully uneventful — and that’s exactly what you want. It tells clients how versions change over time, how to handle large lists of data, what an error looks like, and how to make sure duplicate requests don’t mess things up.Below is a straightforward, ready-to-use...
Salesforce offers a variety of API styles because no two integration scenarios are the same. Some systems need instant, real-time updates. Others deal with huge data volumes. Some workflows demand multi-step transactions, while certain UIs just need a few precisely nested fields.This guide walks you through the main Salesforce API...
When Salesforce consumes external events (for example, Platform Events published by another system), your integration logic must be resilient. Failures will happen — networks time out, APIs throttle, or payloads contain invalid data. A robust event consumer does two key things: It retries transient errors safely without looping forever. It...
Salesforce provides two powerful ways to move events in and out of the Event Bus — the modern Pub/Sub API and the Streaming API family (CometD/EMP). Both deliver events with at-least-once semantics and support replay, but they differ in transport protocols, performance, payload formats, and operational fit. Understanding these differences...
