Documentation

Installation

To use twilio-go in your project initialize go modules then run:

go get github.com/twilio/twilio-go

Getting Started

Getting started with the Twilio API couldn't be easier. Create a RestClient and you're ready to go.

API Credentials

The Twilio RestClient needs your Twilio credentials. You should pass these directly to the constructor (see the code below).

package main

import "github.com/twilio/twilio-go"

func main() {
    accountSid := "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    authToken := "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
    client := twilio.NewRestClient(accountSid, authToken)
}

package main

import "github.com/twilio/twilio-go"

func main() {
    accountSid := "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    authToken := "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
    subaccountSid := "ACYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
    client := twilio.NewRestClientWithParams(accountSid, authToken, twilio.RestClientParams{
        AccountSid: subaccountSid,
    })
}

We suggest storing your credentials as environment variables and then use it in your code. Why? You'll never have to worry about committing your credentials and accidentally posting them somewhere public.

package main

import (
    "github.com/twilio/twilio-go"
    "os"
)

func main() {
    accountSid := os.Getenv("TWILIO_ACCOUNT_SID")
    authToken := os.Getenv("TWILIO_AUTH_TOKEN")
    client := twilio.NewRestClient(accountSid, authToken)
}

Specify a Region and/or Edge

package main

import (
    "github.com/twilio/twilio-go"
    "os"
)

func main() {
    accountSid := os.Getenv("TWILIO_ACCOUNT_SID")
    authToken := os.Getenv("TWILIO_AUTH_TOKEN")
    client := twilio.NewRestClient(accountSid, authToken)
    client.SetRegion("au1")
    client.SetEdge("sydney")
}

This will result in the hostname transforming from api.twilio.com to api.sydney.au1.twilio.com.

A Twilio client constructed without these parameters will also look for TWILIO_REGION and TWILIO_EDGE variables inside the current environment.

Buy a phone number

package main

import (
    "fmt"
    "github.com/twilio/twilio-go"
    openapi "github.com/twilio/twilio-go/rest/api/v2010"
    "os"
)

func main() {
    accountSid := os.Getenv("TWILIO_ACCOUNT_SID")
    authToken := os.Getenv("TWILIO_AUTH_TOKEN")
    phoneNumber := "AVAILABLE_TWILIO_PHONE_NUMBER"
    subaccountSid := os.Getenv("TWILIO_SUBACCOUNT_SID")

    client := twilio.NewRestClientWithParams(accountSid, authToken, twilio.RestClientParams{
        AccountSid: subaccountSid,
    })

    params := &openapi.CreateIncomingPhoneNumberParams{}
    params.SetPhoneNumber(phoneNumber)

    resp, err := client.ApiV2010.CreateIncomingPhoneNumber(params)
    if err != nil {
        fmt.Println(err.Error())
        err = nil
    } else {
        fmt.Println("Phone Number Status: " + *resp.Status)
    }
}

    "os"
)

    accountSid := os.Getenv("TWILIO_ACCOUNT_SID")
    authToken := os.Getenv("TWILIO_AUTH_TOKEN")
    from := os.Getenv("TWILIO_FROM_PHONE_NUMBER")

    subaccountSid := os.Getenv("TWILIO_SUBACCOUNT_SID")

    client := twilio.NewRestClientWithParams(accountSid, authToken, twilio.RestClientParams{
        AccountSid: subaccountSid,
    })

    params := &openapi.CreateMessageParams{}
    params.SetTo(to)
    params.SetFrom(from)
    params.SetBody("Hello there")

    resp, err := client.ApiV2010.CreateMessage(params)
    if err != nil {
        fmt.Println(err.Error())
        err = nil
    } else {

Advanced Usage

Using Standalone Products

Don't want to import the top-level Twilio RestClient with access to the full suite of Twilio products? Use standalone product services instead:

package main

import (
    "os"

    "github.com/twilio/twilio-go/client"
    apiv2010 "github.com/twilio/twilio-go/rest/api/v2010"
    serverless "github.com/twilio/twilio-go/rest/serverless/v1"
)

func main() {
    accountSid := os.Getenv("TWILIO_ACCOUNT_SID")
    authToken := os.Getenv("TWILIO_AUTH_TOKEN")

    // Create an instance of our default BaseClient implementation
    defaultClient := &client.Client{
        Credentials: client.NewCredentials(accountSid, authToken),
    }
    defaultClient.SetAccountSid(accountSid)

    coreApiService := apiv2010.NewApiServiceWithClient(defaultClient)
    serverlessApiService := serverless.NewApiServiceWithClient(defaultClient)
}

Using a Custom Client

package main

import (
    "fmt"
    "net/http"
    "net/url"
    "os"

    "github.com/twilio/twilio-go"
    "github.com/twilio/twilio-go/client"
    openapi "github.com/twilio/twilio-go/rest/api/v2010"
)

type MyClient struct {
    client.Client
}

func (c *MyClient) SendRequest(method string, rawURL string, data url.Values, headers map[string]interface{}) (*http.Response, error) {
    // Custom code to pre-process request here
    resp, err := c.Client.SendRequest(method, rawURL, data, headers)
    // Custom code to pre-process response here
    fmt.Println(resp.StatusCode)
    return resp, err
}

func main() {
    accountSid := os.Getenv("TWILIO_ACCOUNT_SID")
    authToken := os.Getenv("TWILIO_AUTH_TOKEN")

    customClient := &MyClient{
        Client: client.Client{
            Credentials: client.NewCredentials(accountSid, authToken),
        },
    }
    customClient.SetAccountSid(accountSid)

    twilioClient := twilio.NewRestClientWithParams(accountSid, authToken, twilio.RestClientParams{Client: customClient})

    // You may also use custom clients with standalone product services
    twilioApiV2010 := openapi.NewApiServiceWithClient(customClient)
}
