Salesforce orgs grow fast. Hardcoded values in Apex, flows, and validation rules grow even faster… and suddenly every small change needs a deployment.

Custom Metadata Types (CMDTs) are Salesforce’s answer to this problem. They let you store configuration as metadata, deploy it with records, and reference it from Apex, Flow, and formulas without blowing up SOQL limits.

In this guide, we walk through:

The difference between Custom Metadata Types and Custom Settings

How CMDTs behave under the hood (caching, limits, deployability)

Step-by-step: creating a Feature Toggle CMDT

Using CMDT in Apex (get All (), get Instance ()), Flow, and formulas

Use cases: feature flags, tax tables, region mappings, integration endpoints

Best practices for naming, validation, and version control

If you’re building scalable Salesforce apps or maintaining a large org, CMDTs should be your default for reusable configuration.

Custom Metadata Types (CMDTs) in Salesforce are a game-changer for building scalable, configurable applications 🚀. Instead of relying on hardcoding, you can manage feature toggles, reusable rules, integration endpoints, and environment-specific settings with ease. CMDTs are deployable, packageable, and version-controlled, making them perfect for enterprise projects. They integrate seamlessly with Apex, Flows, and formulas, which means both admins and developers can reduce code maintenance and keep apps flexible. CMDTs are cached at runtime, so they don’t consume SOQL limits, keeping performance high ⚡. Whether you need to manage lookup tables, default values, or business rules, CMDTs give you more control and help simplify your Salesforce projects. 👉 Save this guide for later and explore step-by-step instructions to use CMDTs the right way.
