Salesforce MuleSoft Developer study guide
Salesforce MuleSoft Developer · Work through your exam, one topic at a time.
The Salesforce Certified MuleSoft Developer I credential - often listed as the MuleSoft Certified Developer – Level 1 (Mule 4) - is an entry-level certification for integration developers who build and maintain APIs on MuleSoft's Anypoint Platform. It is aimed at practitioners who are expected to design an API specification, deploy and manage an API implementation, write Mule flows that expose RESTful behavior, transform payloads with DataWeave, and control event flow while handling errors correctly. The Salesforce MuleSoft Developer study guide has 5 sections and about 1,729 words.
01Explaining and Creating API Specifications with Anypoint Platform
Anypoint Platform lets you define a contract before any implementation exists. RAML 1.0 is authored in Design Center's API Designer, either as a stand-alone API specification project or as a fragment project (library, data type, trait, resource type, or OAS component) published to Exchange and reused with uses: (RAML) or $ref (OAS).

Implementations run on CloudHub (1.0 or 2.0), a standalone Mule runtime or cluster, or Runtime Fabric. CloudHub 1.0 scales with workers of a chosen vCore size; CloudHub 2.0 scales with replicas inside a target space.

When you scaffold from a spec, the APIkit Router ( <apikit:router config-ref="api-config"/ ) sits in the main flow right after the HTTP Listener. It matches method plus path and routes to flows named exactly like get: :api-config or post: \{orderId} :api-config .

A DataWeave file starts with %dw 2.0 , optionally import / include statements, then declarations ( var , fun , type ) separated from the output expression by --- . Use fun for reusable logic and type for custom schemas.

Mule 4 uses on-error-propagate (handle, then rethrow to the parent or HTTP listener) and on-error-continue (handle and return normally - whatever the handler produces becomes the response for an HTTP listener). Handlers attach to flows, to global configuration ( defaultErrorHandler ), and to try scopes.
