Go API client for finnhub.io

Overview

API documentation: https://finnhub.io/docs/api
API version: 1.0.0
Package version: 2.0.15

Installation

Using Go Modules

Make sure your project is using Go Modules (it will have a go.mod file in its root if it already is):

go mod init

Then, reference finnhub-go in a Go program with import:

import (
    finnhub "github.com/Finnhub-Stock-API/finnhub-go/v2"
)

Run any of the normal go commands (build/install/test). The Go toolchain will resolve and fetch the finnhub-go module automatically.

Alternatively, you can also explicitly go get the package into a project:

$ go get -u github.com/Finnhub-Stock-API/finnhub-go/v2

Using `go get`

If you don't want to use Go Modules, you can choose to get the library directly:

$ go get -u github.com/Finnhub-Stock-API/finnhub-go

Then, reference finnhub-go in a Go program with import (Note that no /v2 at the end):

import (
    finnhub "github.com/Finnhub-Stock-API/finnhub-go"
)
