twilio-go

A client for accessing the Twilio API with several nice features:

  • Easy-to-use helpers for purchasing phone numbers and sending MMS messages

  • E.164 support, times that are parsed into a time.Time, and other smart types.

  • Finer grained control over timeouts with a Context, and the library uses wall-clock HTTP timeouts, not socket timeouts.

  • Easy debugging network traffic by setting DEBUG_HTTP_TRAFFIC=true in your environment.

  • Easily find calls and messages that occurred between a particular set of time.Times, down to the nanosecond, with GetCallsInRange / GetMessagesInRange.

  • It's clear when the library will make a network request, there are no unexpected latency spikes when paging from one resource to the next.

  • Uses threads to fetch resources concurrently; for example, has methods to fetch all Media for a Message concurrently.

  • Usable, one sentence descriptions of Alerts.

Here are some example use cases:

const sid = "AC123"
const token = "456bef"

client := twilio.NewClient(sid, token, nil)

// Send a message
msg, err := client.Messages.SendMessage("+14105551234", "+14105556789", "Sent via go :) ✓", nil)

// Start a phone call
call, err := client.Calls.MakeCall("+14105551234", "+14105556789",
        "https://kev.inburke.com/zombo/zombocom.mp3")

// Buy a number
number, err := client.IncomingNumbers.BuyNumber("+14105551234")

// Get all calls from a number
data := url.Values{}
data.Set("From", "+14105551234")
callPage, err := client.Calls.GetPage(context.TODO(), data)

// Iterate over calls
iterator := client.Calls.GetPageIterator(url.Values{})
for {
    page, err := iterator.Next(context.TODO())
    if err == twilio.NoMoreResults {
        break
    }
    fmt.Println("start", page.Start)
}

A complete documentation reference can be found at godoc.org.

The API is open to, but unlikely to change, and currently only covers these resources:

  • Alerts
  • Applications
  • Calls
  • Conferences
  • Incoming Phone Numbers
  • Keys
  • Messages
  • Media
  • Outgoing Caller ID's
  • Queues
  • Recordings
  • Transcriptions
  • Access Tokens for IPMessaging, Video and Programmable Voice SDK
  • Pricing
Error Parsing

If the twilio-go client gets an error from the Twilio API, we attempt to convert it to a rest.Error before returning. Here's an example 404.

&rest.Error{
    Title: "The requested resource ... was not found",
    ID: "20404",
    Detail: "",
    Instance: "",
    Type: "https://www.twilio.com/docs/errors/20404",
    StatusCode: 404
}

Not all errors will be a rest.Error however - HTTP timeouts, canceled context.Contexts, and JSON parse errors (HTML error pages, bad gateway responses from proxies) may also be returned as plain Go errors.

Twiml Generation

There are no plans to support Twiml generation in this library. It may be more readable and maintainable to manually write the XML involved in a Twiml response.

API Problems this Library Solves For You

  • Media URL's are returned over HTTP. twilio-go rewrites these URL's to be HTTPS before returning them to you.

  • A subset of Notifications returned code 4107, which doesn't exist. These notifications should have error code 14107. We rewrite the error code internally before returning it to you.

  • The only provided API for filtering calls or messages by date grabs all messages for an entire day, and the day ranges are only available for UTC. Use GetCallsInRange or GetMessagesInRange to do timezone-aware, finer-grained date filtering.

Errata

You can get Alerts for a given Call or MMS by passing ResourceSid=CA123 as a filter to Alerts.GetPage. This functionality is not documented in the API.

Overview

Package twilio simplifies interaction with the Twilio API.

The twilio-go library should be your first choice for interacting with the Twilio API; it offers forward compatibility, very fine-grained control of API access, best-in-class control over how long to wait for requests to complete, and great debuggability when things go wrong. Get started by creating a Client: 

client := twilio.NewClient("AC123", "123", nil)

All of the Twilio resources are available as properties on the Client. Let's walk through some of the example use cases.

Creating a Resource

Resources that can create new methods take a url.Values as an argument, and pass all arguments to the Twilio API. This method ensures forward compatibility; any new arguments that get invented can be added in client-side code. 

data := url.Values{"To": []string{"+1foo"}, "From": []string{"+1foo"},
    "Body": []string{"+1foo"}}
msg, err := client.Messages.Create(context.TODO(), data)

Getting an Instance Resource

Call Get() with a particular sid. 

number, err := client.IncomingNumbers.Get(context.TODO(), "PN123")
fmt.Println(number.PhoneNumber)

Updating an Instance Resource

Call Update() with a particular sid and a url.Values. 

data := url.Values{}
data.Set("Status", string(twilio.StatusCompleted))
call, err := client.Calls.Update("CA123", data)

Getting a List Resource

There are two flavors of interaction. First, if all you want is a single Page of resources, optionally with filters: 

page, err := client.Recordings.GetPage(context.TODO(), url.Values{})

To control the page size, set "PageSize": "N" in the url.Values{} field. Twilio defaults to returning 50 results per page if this is not set.

Alternatively you can get a PageIterator and call Next() to repeatedly retrieve pages. 

iterator := client.Calls.GetPageIterator(url.Values{"From": []string{"+1foo"}})
for {
    page, err := iterator.Next(context.TODO())
    // NoMoreResults means you've reached the end.
    if err == twilio.NoMoreResults {
        break
    }
    fmt.Println("start", page.Start)
}

Twilio Monitor

Twilio Monitor subresources are available on the Client under the Monitor field, e.g. 

alert, err := client.Monitor.Alerts.Get(context.TODO(), "NO123")

Custom Types

There are several custom types and helper functions designed to make your job easier. Where possible, we try to parse values from the Twilio API into a datatype that makes more sense. For example, we try to parse timestamps into Time values, durations into time.Duration, integer values into uints, even if the API returns them as strings, e.g. "3".

All phone numbers have type PhoneNumber. By default these are E.164, but can be printed in Friendly()/Local() variations as well. 

num, _ := twilio.NewPhoneNumber("+1 (415) 555-1234")
fmt.Println(num.Friendly()) // "+1 415 555 1234"

Any times returned from the Twilio API are of type TwilioTime, which has two properties - Valid (a bool), and Time (a time.Time). Check Valid before using the related Time. 

if msg.DateSent.Valid {
    fmt.Println(msg.DateSent.Time.Format(time.Kitchen)
}

There are constants for every Status in the API, for example StatusQueued, which has the value "queued". You can call Friendly() on any Status to get an uppercase version of the status, e.g. 

twilio.StatusInProgress.Friendly() // "In Progress"
Example 
package main

import (
	"fmt"
	"net/url"
	"time"

	"github.com/kevinburke/rest"
	twilio "github.com/saintpete/twilio-go"
	"golang.org/x/net/context"
)

var callURL, _ = url.Parse("https://kev.inburke.com/zombo/zombocom.mp3")

func main() {
	client := twilio.NewClient("AC123", "123", nil)

	// Send a SMS
	msg, _ := client.Messages.SendMessage("+14105551234", "+14105556789", "Sent via go :) ✓", nil)
	fmt.Println(msg.Sid, msg.FriendlyPrice())

	// Make a call
	call, _ := client.Calls.MakeCall("+14105551234", "+14105556789", callURL)
	fmt.Println(call.Sid, call.FriendlyPrice())

	_, err := client.IncomingNumbers.BuyNumber("+1badnumber")
	// Twilio API errors are converted to rest.Error types
	if err != nil {
		restErr, ok := err.(*rest.Error)
		if ok {
			fmt.Println(restErr.Title)
			fmt.Println(restErr.Type)
		}
	}

	// Find all calls from a number
	data := url.Values{"From": []string{"+14105551234"}}
	iterator := client.Calls.GetPageIterator(data)
	ctx, cancel := context.WithTimeout(context.Background(), 1*time.Minute)
	defer cancel()
	for {
		page, err := iterator.Next(ctx)
		if err == twilio.NoMoreResults {
			break
		}
		for _, call := range page.Calls {
			fmt.Println(call.Sid, call.To)
		}
	}
}

GetAlertsInRange gets an Iterator containing conferences in the range [start, end), optionally further filtered by data. GetAlertsInRange panics if start is not before end. Any date filters provided in data will be ignored. If you have an end, but don't want to specify a start, use twilio.Epoch for start. If you have a start, but don't want to specify an end, use twilio.HeatDeath for end.

Assumes that Twilio returns resources in chronological order, latest first. If this assumption is incorrect, your results will not be correct.

Returned AlertPages will have at most PageSize results, but may have fewer, based on filtering.

func (*AlertService) GetNextAlertsInRange 

func (a *AlertService) GetNextAlertsInRange(start time.Time, end time.Time, nextPageURI string) AlertPageIterator

GetNextAlertsInRange retrieves the page at the nextPageURI and continues retrieving pages until any results are found in the range given by start or end, or we determine there are no more records to be found in that range.

If AlertPage is non-nil, it will have at least one result.

func (*AlertService) GetPage 

func (a *AlertService) GetPage(ctx context.Context, data url.Values) (*AlertPage, error)

GetPage returns a single Page of resources, filtered by data.

func (*CallService) GetCallsInRange 

func (c *CallService) GetCallsInRange(start time.Time, end time.Time, data url.Values) CallPageIterator

GetCallsInRange gets an Iterator containing calls in the range [start, end), optionally further filtered by data. GetCallsInRange panics if start is not before end. Any date filters provided in data will be ignored. If you have an end, but don't want to specify a start, use twilio.Epoch for start. If you have a start, but don't want to specify an end, use twilio.HeatDeath for end.

Assumes that Twilio returns resources in chronological order, latest first. If this assumption is incorrect, your results will not be correct.

Returned CallPages will have at most PageSize results, but may have fewer, based on filtering.

Example 
package main

import (
	"fmt"
	"log"
	"net/url"
	"time"

	twilio "github.com/saintpete/twilio-go"
	"golang.org/x/net/context"
)

func main() {
	// Get all calls between 10:34:00 Oct 26 and 19:25:59 Oct 27, NYC time.
	nyc, _ := time.LoadLocation("America/New_York")
	start := time.Date(2016, 10, 26, 22, 34, 00, 00, nyc)

	iter := client.Calls.GetCallsInRange(start, end, url.Values{})
	ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
	defer cancel()
	for {
		page, err := iter.Next(ctx)
		if err == twilio.NoMoreResults {
			break
		}
		if err != nil {
			log.Fatal(err)
		}
		for i, call := range page.Calls {
			fmt.Printf("%d: %s (%s)", i, call.Sid, call.DateCreated.Time)
		}
	}

type MessageService 

type MessageService struct {
	// contains filtered or unexported fields
}

func (*MessageService) Create 

func (m *MessageService) Create(ctx context.Context, data url.Values) (*Message, error)

Create a message with the given url.Values. For more information on valid values, see https://www.twilio.com/docs/api/rest/sending-messages or use the SendMessage helper.

func (*MessageService) Get 

func (m *MessageService) Get(ctx context.Context, sid string) (*Message, error)

func (*MessageService) GetMediaURLs 

func (m *MessageService) GetMediaURLs(ctx context.Context, sid string, data url.Values) ([]*url.URL, error)

GetMediaURLs gets the URLs of any media for this message. This uses threads to retrieve all URLs simultaneously; if retrieving any URL fails, we return an error for the entire request.

The data can be used to filter the list of returned Media as described here: https://www.twilio.com/docs/api/rest/media#list-get-filters

As of October 2016, only 10 MediaURLs are permitted per message. No attempt is made to page through media resources; omit the PageSize parameter in data, or set it to a value greater than 10, to retrieve all resources.

func (*MessageService) GetMessagesInRange 

func (c *MessageService) GetMessagesInRange(start time.Time, end time.Time, data url.Values) MessagePageIterator

GetMessagesInRange gets an Iterator containing calls in the range [start, end), optionally further filtered by data. GetMessagesInRange panics if start is not before end. Any date filters provided in data will be ignored. If you have an end, but don't want to specify a start, use twilio.Epoch for start. If you have a start, but don't want to specify an end, use twilio.HeatDeath for end.

Assumes that Twilio returns resources in chronological order, latest first. If this assumption is incorrect, your results will not be correct.

Returned MessagePages will have at most PageSize results, but may have fewer, based on filtering.

Example 
package main

import (
	"fmt"
	"log"
	"net/url"
	"time"

	twilio "github.com/saintpete/twilio-go"
	"golang.org/x/net/context"
)

func main() {
	// Get all messages between 10:34:00 Oct 26 and 19:25:59 Oct 27, NYC time.
	nyc, _ := time.LoadLocation("America/New_York")
	start := time.Date(2016, 10, 26, 22, 34, 00, 00, nyc)
	end := time.Date(2016, 10, 27, 19, 25, 59, 00, nyc)

	client := twilio.NewClient("AC123", "123", nil)
	iter := client.Messages.GetMessagesInRange(start, end, url.Values{})
	ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
	defer cancel()
	for {
		page, err := iter.Next(ctx)
		if err == twilio.NoMoreResults {
			break
		}
		if err != nil {
			log.Fatal(err)
		}
		for i, message := range page.Messages {
			fmt.Printf("%d: %s (%s)", i, message.Sid, message.DateCreated.Time)
		}
	}
}

Output:

func (*MessageService) GetNextMessagesInRange 

func (c *MessageService) GetNextMessagesInRange(start time.Time, end time.Time, nextPageURI string) MessagePageIterator

GetNextMessagesInRange retrieves the page at the nextPageURI and continues retrieving pages until any results are found in the range given by start or end, or we determine there are no more records to be found in that range.

If MessagePage is non-nil, it will have at least one result.

func (*MessageService) GetPage 

func (m *MessageService) GetPage(ctx context.Context, data url.Values) (*MessagePage, error)

GetPage returns a single page of resources. To retrieve multiple pages, use GetPageIterator.
