Set the API key and API key secret to environment variables.

export GOTWI_API_KEY=your-api-key
export GOTWI_API_KEY_SECRET=your-api-key-secret

This authentication method allows only read-only access to public information.

package main

import (
	"context"
	"fmt"

	"github.com/michimani/gotwi"
	"github.com/michimani/gotwi/fields"
	"github.com/michimani/gotwi/users"
	"github.com/michimani/gotwi/users/types"
)

func main() {
	in := &gotwi.NewGotwiClientInput{
		AuthenticationMethod: gotwi.AuthenMethodOAuth2BearerToken,
	}

	c, err := gotwi.NewGotwiClient(in)
	if err != nil {
		fmt.Println(err)
		return
	}

	p := &types.UserLookupByUsernameParams{
		Username: "michimani210",
		Expansions: fields.ExpansionList{
			fields.ExpansionPinnedTweetID,
		},
		UserFields: fields.UserFieldList{
			fields.UserFieldCreatedAt,
		},
		TweetFields: fields.TweetFieldList{
			fields.TweetFieldCreatedAt,
		},
	}
	res, err := users.UserLookupByUsername(context.Background(), c, p)
	if err != nil {
		fmt.Println(err)
		return
	}

	fmt.Println("ID: ", gotwi.StringValue(u.Data.ID))
	fmt.Println("Name: ", gotwi.StringValue(u.Data.Name))
	fmt.Println("Username: ", gotwi.StringValue(u.Data.Username))
	fmt.Println("CreatedAt: ", u.Data.CreatedAt)
	if u.Includes.Tweets != nil {
		for _, t := range u.Includes.Tweets {
			fmt.Println("PinnedTweet: ", gotwi.StringValue(t.Text))
		}
	}
}

go run main.go

You will get the output like following.

ID:  581780917
Name:  michimani Lv.859
Username:  michimani210
CreatedAt:  2012-05-16 12:07:04 +0000 UTC
PinnedTweet:  pinned tweet

If you already have a pre-generated access token (e.g. OAuth 2.0 Authorization Code with PKCE), you can use NewGotwiClientWithAccessToken() function to generate a Gotwi client.

in := &gotwi.NewGotwiClientWithAccessTokenInput{
	AccessToken: "your-access-token",
}

c, err := gotwi.NewGotwiClientWithAccessToken(in)
if err != nil {
	// error handling
}

With this authentication method, each operation will be performed as the authenticated Twitter account. For example, you can tweet as that account, or retrieve accounts that are blocked by that account.

package main

import (
	"context"
	"fmt"

	"github.com/michimani/gotwi"
	"github.com/michimani/gotwi/tweets"
	"github.com/michimani/gotwi/tweets/types"
)

func main() {
	in := &gotwi.NewGotwiClientInput{
		AuthenticationMethod: gotwi.AuthenMethodOAuth1UserContext,
		OAuthToken:           "your-twitter-acount-oauth-token",
		OAuthTokenSecret:     "your-twitter-acount-oauth-token-secret",
	}

	c, err := gotwi.NewGotwiClient(in)
	if err != nil {
		fmt.Println(err)
		return
	}

	p := &types.ManageTweetsPostParams{
		Text: gotwi.String("This is a test tweet with poll."),
		Poll: &types.ManageTweetsPostParamsPoll{
			DurationMinutes: gotwi.Int(5),
			Options: []string{
				"Cyan",
				"Magenta",
				"Yellow",
				"Key plate",
			},
		},
	}

	res, err := tweets.ManageTweetsPost(context.Background(), c, p)
	if err != nil {
		fmt.Println(err.Error())
		return
	}

	fmt.Printf("[%s] %s\n", gotwi.StringValue(res.Data.ID), gotwi.StringValue(res.Data.Text))
}

go run main.go

You will get the output like following.

[1462813519607263236] This is a test tweet with poll.

Each function that calls the Twitter API (e.g. TweetRetweetsRetweetedBy()) may return an error for some reason. If the error is caused by the Twitter API returning a status other than 2XX, you can check the details by doing the following.

res, err := tweets.TweetRetweetsRetweetedBy(context.Background(), c, p)
if err != nil {
	fmt.Println(err)

	// more error information
	ge := err.(*gotwi.GotwiError)
	if ge.OnAPI {
		fmt.Println(ge.Title)
		fmt.Println(ge.Detail)
		fmt.Println(ge.Type)
		fmt.Println(ge.Status)
		fmt.Println(ge.StatusCode)

		for _, ae := range ge.APIErrors {
			fmt.Println(ae.Message)
			fmt.Println(ae.Label)
			fmt.Println(ae.Parameters)
			fmt.Println(ae.Code)
			fmt.Println(ae.Code.Detail())
		}

		if ge.RateLimitInfo != nil {
			fmt.Println(ge.RateLimitInfo.Limit)
			fmt.Println(ge.RateLimitInfo.Remaining)
			fmt.Println(ge.RateLimitInfo.ResetAt)
		}
	}
}
