Tooling API

API for fine-grained access to development metadata, used by IDEs and tools to query code, run tests and manage debug logs.

Definition

The Tooling API exposes objects such as ApexClass, ApexCodeCoverage and TraceFlag through SOQL and REST/SOAP, allowing tools to inspect and update individual components quickly. The Developer Console and many IDE features are built on it.

Exam tip

Choose Tooling API when the question involves querying code coverage or managing debug logs programmatically.
