How to Migrate Your Go SMS Application from Twilio to Plivo

Jan 27, 2022

Migrating your Go SMS application from Twilio to Plivo is a seamless and painless process. The two companies’ API structures, implementation mechanisms, XML structure, SMS message processing, and voice call processing are similar. We wrote this technical comparison so that you can scope between Twilio and Plivo APIs for a seamless migration.

Understanding the differences between Twilio and Plivo development

Most of the APIs and features that are available on Twilio are also available on Plivo and the implementation mechanism is easier as the steps involved are almost identical. This table gives a side-side comparison of the two companies’ features and APIs. An added advantage with Plivo is that not only can you code using the old familiar API/XML method, you can also implement your use cases using PHLO (Plivo High Level Objects), a visual workflow builder that lets you create workflows by dragging and dropping components onto a canvas — no coding required.

Features and APIs	Twilio	Plivo	Similarities	Implementation Interface
SMS API: Send SMS/MMS messages	✅	✅	Request and response variables’ structure	API PHLO
Managed number pool for US/CA Messaging	Copilot	Powerpack	Feature parity	API Console
Geo Permissions	✅	✅	Feature parity	Console
SMS Sender ID registration	✅	✅	Feature parity	Console
Number Lookup API	✅	✅	API Parity	API
Phone number management	✅	✅	Feature parity	API Console
Validating Requests	✅	✅	Feature parity	API XML
Subaccounts	✅	✅	Feature parity	API
HTTP callbacks	✅	✅	Feature parity	API XML PHLO

Plivo offers one unique advantage: Not only can you code using APIs and XML, you can also implement your use cases using PHLO (Plivo High Level Objects), a visual workflow builder that lets you create workflows by dragging and dropping components onto a canvas — no coding required.

Plivo account creation

Start by signing up for a free trial account that you can use to experiment with and learn about our services. The free trial account comes with free credits, and you can add more as you go along. You can also add a phone number to your account to start testing the full range of our voice and SMS features. A page in our support portal walks you through the signup process.

You can also port your numbers from Twilio to Plivo, as we explain in this guide.

Migrating your Go SMS application

You can migrate your existing application from Twilio to Plivo by refactoring the code, or you can try our intuitive visual workflow builder PHLO. To continue working with the APIs, use one of the quickstart guides to set up a development environment for your preferred language. Plivo offers server SDKs in seven languages: Python, Node.js, .NET, Java, Python, Ruby, and Go. For another alternative that lets you evaluate Plivo’s SMS APIs and their request and response structure, use our Postman collections.

How to send an SMS message

Let’s take a look at the process of refactoring the code to migrate your app from Twilio to Plivo to set up a simple Go application to send an SMS message by changing just a few lines of code.

Twilio Plivo

package main

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

func main() {
    from := 
os.Getenv("TWILIO_FROM_PHONE_NUMBER")
    to := 
os.Getenv("TWILIO_TO_PHONE_NUMBER")
    subaccountSid 
:= os.Getenv("TWILIO_SUBACCOUNT_SID")

    client :=
 twilio.NewRestClientWithParams(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())
    } else {
        response, _ := json.Marshal(*resp)
        fmt.Println("Response: " + string(response))
    }
}

package main

import (
    "fmt"

    "github.com/plivo/plivo-go/v7"
)

func main() {
    client, err: = plivo.NewClient
    ("<auth_id>",
    "<auth_token>", & plivo.ClientOptions {})
    if err != nil {
        fmt.Print("Error", err.Error())
        return
    }
    response, err: = client.Messages.Create(
        plivo.MessageCreateParams {
            Src: "+14151113333",
            Dst: "+14151112222",
            Text: "Hello, this is a sample text",
            URL: "https://foo.com/sms_status/",
        },
    )
    if err != nil {
        fmt.Print("Error", err.Error())
        return
    }
    fmt.Printf("Response: %#v\n", response)
}

Alternatively, you can implement the same functionality using one of our PHLO templates. For example, if you want to send an SMS message, your PHLO would be this:

How to receive and reply to SMS

You can migrate an application for receiving and replying to an incoming SMS from Twilio to Plivo just as seamlessly, as in this example:

Twilio Plivo

package main

import (
    "net/http"
    "encoding/xml"
)

type TwiML struct {
    XMLName xml.Name `xml:"Response"`

    Message string `xml:",omitempty"`
}

func main() {
    http.HandleFunc("/twiml", twiml)
    http.ListenAndServe(":3000", nil)
}

func twiml(w http.ResponseWriter, r * 
http.Request) {
    twiml: = TwiML {
        Message: "Ahoy! Thanks so much for
        your message.'"
    }
    x,
    err: = xml.Marshal(twiml)
    if err != nil {
        http.Error(w, err.Error(), 
        http.StatusInternalServerError)
        return
    }

    w.Header().Set("Content-Type",
    "application/xml")
    w.Write(x)
}

package main

import (
    "net/http"
    "plivo-go/xml"
)

func handler(w http.ResponseWriter, r * 
http.Request) {
    fromnumber: = r.FormValue("From")
    tonumber: = r.FormValue("To")
    text: = r.FormValue("Text")
    print("Message Received - ", fromnumber, " ", tonumber, " ", text)

    response: = xml.ResponseElement {
        Contents: [] interface {} {
            new(xml.MessageElement).
            SetDst(tonumber).
            SetSrc(fromnumber).
            SetContents("Thank you, we received
            your request"),
        },
    }
    w.Write([] byte(response.String()))
}

func main() {
    http.HandleFunc("/reply_sms/", handler)
    http.ListenAndServe(":8080", nil)
}

Here again, you can implement the same functionality using one of our PHLO templates. Your PHLO would look like:

How to send an MMS message

Let’s take a look at the process of refactoring the code to migrate your app from Twilio to Plivo to set up a simple Go application to send an MMS message by changing just a few lines of code.

Twilio Plivo

package main

import (
    "fmt"
    twilio "github.com/kevinburke/twilio-go"
    "net/url"
)

func main() {
    client: = twilio.NewClient("TWILIO_AUTH_SID", "TWILIO_AUTH_TOKEN", nil)
    gif,
    _: = url.Parse("https://media.giphy.com/media/uGGT9wVlxPAuk/giphy.gif")
    mms,
    _: = client.Messages.SendMessage("FROM_NUMBER", "TO_NUMBER", "", [] * url.URL {
        gif
    })
    fmt.Println("You just sent a gif with Twilio using Go!! " + string(mms.Status) + " - " + string(mms.Sid))
}

package main

import (
    "fmt"
    plivo "github.com/plivo/plivo-go/v7"
)

func main() {

        client, err: = plivo.NewClient("<auth_id>", "<auth_token>", & plivo.ClientOptions {})
        if err != nil {
            panic(err)
        }
        createResp, err: = client.Messages.Create(plivo.MessageCreateParams {
            Src: "+14151113333",
            Dst: "+14151112222",
            Text: "Hello, from Go!",
            Type: "mms",
            MediaUrls: [] string {
                "https://media.giphy.com/media/26gscSULUcfKU7dHq/source.gif"
            },
            MediaIds: [] string {
                "801c2056-33ab-499c-80ef-58b574a462a2"
            },
        })
        if err != nil {
            panic(err)
        }

Alternatively, you can implement the same functionality using one of our PHLO templates. For example, if you want to send an MMS message, your PHLO would be this:
