Go SDK

The Plivo Go SDK makes it simpler to integrate communications into your Go applications using the Plivo REST API. Using the SDK, you will be able to make voice calls, send SMS and generate Plivo XML to control your call flows.

If you are looking for the community-contributed version of the Go SDK, you can get it here.

Prerequisites

  • Go >= 1.0.x

Installation

You can use the SDK using the go command.

$ go get github.com/plivo/plivo-go

You can also install by cloning this repository into your GOPATH.

Getting started

Authentication

To make the API requests, you need to create a Client and provide it with authentication credentials (which can be found at https://manage.plivo.com/dashboard/).

We recommend that you store your credentials in the PLIVO_AUTH_ID and the PLIVO_AUTH_TOKEN environment variables, so as to avoid the possibility of accidentally committing them to source control. If you do this, you can initialise the client with no arguments and it will automatically fetch them from the environment variables:

package main

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

func main()  {
  client, err := plivo.NewClient("", "", &plivo.ClientOptions{})
  if err != nil {
    panic(err)
  }
}

Alternatively, you can specifiy the authentication credentials while initializing the Client.

package main

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

func main()  {
 client, err := plivo.NewClient("your_auth_id", "your_auth_token", &plivo.ClientOptions{})
 if err != nil {
   panic(err)
 }
}

The Basics

The SDK uses consistent interfaces to create, retrieve, update, delete and list resources. The pattern followed is as follows:

client.Resources.Create(Params{}) // Create
client.Resources.Get(Id) // Get
client.Resources.Update(Id, Params{}) // Update
client.Resources.Delete(Id) // Delete
client.Resources.List() // List all resources, max 20 at a time

Using client.Resources.List() would list the first 20 resources by default (which is the first page, with limit as 20, and offset as 0). To get more, you will have to use limit and offset to get the second page of resources.

Examples

Send a message

package main

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

func main()  {
  client, err := plivo.NewClient("", "", &plivo.ClientOptions{})
  if err != nil {
    panic(err)
  }
  client.Messages.Create(plivo.MessageCreateParams{
    Src: "the_source_number",
    Dst: "the_destination_number",
    Text: "Hello, world!",
  })
}

Make a call

package main

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

func main()  {
  client, err := plivo.NewClient("", "", &plivo.ClientOptions{})
  if err != nil {
    panic(err)
  }
  client.Calls.Create(plivo.CallCreateParams{
    From: "the_source_number",
    To: "the_destination_number",
    AnswerURL: "http://answer.url",
  })
}

Generate Plivo XML

package main

import "github.com/plivo/plivo-go/plivo/xml"

func main()  {
  println(xml.ResponseElement{
    Contents: []interface{}{
      new(xml.SpeakElement).SetContents("Hello, world!"),
    },
    }.String())
}

This generates the following XML:

<Response>
  <Speak>Hello, world!</Speak>
</Response>
