Code Generation Settings Overview

APIMatic code generation feature allows you to effortlessly create API client libraries across multiple programming languages. Throughout the code generation process, you have the flexibility to configure different settings to customize these SDKs according to your specific requirements.

This section offers a comprehensive overview of these CodeGen settings, their functionalities, and instructions on how to use them.


You can import your API definition file along with a metadata file apimatic-metadata.json that will allow you to configure these settings.

Endpoint Settings

Return Complete HTTP ResponseThis setting returns complete HTTP response including headers and status code.
Use HTTP Method PrefixThis setting allows to prefix the HTTP method Get, Update, or Delete to the name of the methods.
Encode Template ParametersThis setting encodes endpoint level parameters.

Collapse Params to ArrayThis setting collapses more than 1 parameters into an options array.
Use Endpoint Method NameUse the MethodName in the endpoint entity to name endpoints instead of the Name property.
Nullify 404This setting returns null response on the HTTP status code 404 instead of throwing an exception.

Model Settings

Enable Additional Model PropertiesThis setting allows to add additional properties of models that are not part of the model description.
Use Model PrefixThis setting allows to postfix each model class with the word "Model".
Generate ModelsThis setting allows to switch between using models and maps.

Client Interface NameThis setting sets the class name of the client library interface.
Use Security Scheme Name For Single AuthEnable this setting to derive the auth interface name from the auth scheme name specified in the API definition.
Do Not Split WordsThis setting lists words that should not be split, regardless of the capitalization.
Synchronous Mode of CodeEnable this setting to generate asynchronous code and disable it for synchronous code.
Enable LoggingEnable this setting to generate code in the SDKs for logging events in the API cycle using a library.
Symbolize Hash Keys in RubyEnable this setting to use symbols instead of strings for hash keys in Ruby SDKs.
Underscore NumbersThis setting adds underscores before and after numbers in the generated SDKs.
