Generate a Go SDK by following the instructions on this page.

This guide assumes that you already have an initialized fern folder on your local machine. See Set up the fern folder for more details.
1

Pass fern check

Run fern check to ensure that your API definition is valid. If there are any errors, fix them before proceeding.

If you’re using an OpenAPI Specification, check out all of our supported extensions.

2

Add the SDK generator

Add the Go SDK generator:

$fern add fern-go-sdk --group go-sdk

go-sdk is the name of the generators.yml group that configures your Go SDK’s output location and other metadata. You can customize this group name to differentiate between multiple SDKs across different languages (e.g., ruby-sdk, etc) in your organization.

This command adds the following to generators.yml:

1  go-sdk:
2    generators:
3      - name: fernapi/fern-go-sdk
4        version: 4.23.2
5        output:
6          location: local-file-system
7          path: ../sdks/go
3

Generate the SDK

Generate the SDK:

$fern generate --group go-sdk

This creates a sdks folder in your current directory. The resulting folder structure looks like this:

$fern/ # created by fern init
$sdks/ # created by fern generate --group go-sdk
$├─ go
$    ├─ core/
$    └─ go.mod
