plivo-go's Introduction

plivo-go

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 messages and generate Plivo XML to control your call flows.

Prerequisites

Go >= 1.13.x

Getting started

The steps described below uses go modules.

Create a new project (optional)

$ mkdir ~/helloplivo
$ cd ~/helloplivo
$ go mod init helloplivo

This will generate a go.mod and go.sum file.

Add plivo-go as a dependency to your project

$ go get github.com/plivo/plivo-go/v7

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/v7"

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/v7"

func main()  {
	client, err := plivo.NewClient("<auth-id>", "<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/v7"

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/v7"

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",
	})
}

Lookup a number

package main

import (
	"fmt"
	"log"

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

func main() {
	client, err := plivo.NewClient("<auth-id>", "<auth-token>", &plivo.ClientOptions{})
	if err != nil {
		log.Fatalf("plivo.NewClient() failed: %s", err.Error())
	}

	resp, err := client.Lookup.Get("<insert-number-here>", plivo.LookupParams{})
	if err != nil {
		if respErr, ok := err.(*plivo.LookupError); ok {
			fmt.Printf("API ID: %s\nError Code: %d\nMessage: %s\n",
				respErr.ApiID, respErr.ErrorCode, respErr.Message)
			return
		}
		log.Fatalf("client.Lookup.Get() failed: %s", err.Error())
	}

	fmt.Printf("%+v\n", resp)
}

Generate Plivo XML

package main

import "github.com/plivo/plivo-go/v7/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>

Run a PHLO

package main

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

// Initialize the following params with corresponding values to trigger resources

const authId = "auth_id"
const authToken = "auth_token"
const phloId = "phlo_id"

// with payload in request

func main() {
	testPhloRunWithParams()
}

func testPhloRunWithParams() {
	phloClient, err := plivo.NewPhloClient(authId, authToken, &plivo.ClientOptions{})
	if err != nil {
		panic(err)
	}
	phloGet, err := phloClient.Phlos.Get(phloId)
	if err != nil {
		panic(err)
	}
	//pass corresponding from and to values
	type params map[string]interface{}
	response, err := phloGet.Run(params{
		"from": "111111111",
		"to":   "2222222222",
	})

	if err != nil {
		println(err)
	}
	fmt.Printf("Response: %#v\n", response)
}

WhatsApp Messaging

Plivo's WhatsApp API allows you to send different types of messages over WhatsApp, including templated messages, free form messages and interactive messages. Below are some examples on how to use the Plivo Go SDK to send these types of messages.

Templated Messages

Templated messages are a crucial to your WhatsApp messaging experience, as businesses can only initiate WhatsApp conversation with their customers using templated messages.

WhatsApp templates support 4 components: header , body, footer and button. At the point of sending messages, the template object you see in the code acts as a way to pass the dynamic values within these components. header can accomodate text or media (images, video, documents) content. body can accomodate text content. button can support dynamic values in a url button or to specify a developer-defined payload which will be returned when the WhatsApp user clicks on the quick_reply button. footer cannot have any dynamic variables.

Example:

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.Println("Error:", err)
		return
	}

	// Create a WhatsApp template
	template, err := plivo.CreateWhatsappTemplate(`{ 
            "name": "sample_purchase_feedback",
            "language": "en_US",
            "components": [
                {
                    "type": "header",
                    "parameters": [
                        {
                            "type": "media",
                            "media": "https://xyz.com/img.jpg"
                        }
                    ]
                },
                {
                    "type": "body",
                    "parameters": [
                        {
                            "type": "text",
                            "text": "Water Purifier"
                        }
                    ]
                }
            ]
          }`)
	if err != nil {
		fmt.Println("Error creating template:", err)
		return
	}

	// Send a templated message
	response, err := client.Messages.Create(plivo.MessageCreateParams{
		Src:     "source_number",
		Dst:     "destination_number",
		Type:    "whatsapp",
		Template: &template,
	})
	if err != nil {
		fmt.Println("Error sending message:", err)
		return
	}

	fmt.Printf("Response: %#v\n", response)
}

Free Form Messages

Non-templated or Free Form WhatsApp messages can be sent as a reply to a user-initiated conversation (Service conversation) or if there is an existing ongoing conversation created previously by sending a templated WhatsApp message.

Free Form Text Message

Example:

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.Println("Error:", err)
		return
	}

	// Send a free form message
	response, err := client.Messages.Create(plivo.MessageCreateParams{
		Src:  "source_number",
		Dst:  "destination_number",
		Text: "Hello! How can I help you today?",
		Type: "whatsapp",
	})
	if err != nil {
		fmt.Println("Error sending message:", err)
		return
	}

	fmt.Printf("Response: %#v\n", response)
}

Free Form Media Message

Example:

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:"source_number",
			Dst:"destination_number",
			Type:"whatsapp", 
			Text:"Hello, this is sample text",
			MediaUrls:[]string{"https://sample-videos.com/img/Sample-png-image-1mb.png"},
			URL: "https://foo.com/whatsapp_status/",
		})
         if err != nil {
			fmt.Print("Error sending message:", err.Error())
			return
        }
        fmt.Printf("Response: %#v\n", response)
}

Interactive Messages

This guide shows how to send non-templated interactive messages to recipients using Plivo’s APIs.

Quick Reply Buttons

Quick reply buttons allow customers to quickly respond to your message with predefined options.

Example:

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.Println("Error:", err)
		return
	}

	// Create quick reply buttons
	interactive, err := plivo.CreateWhatsappInteractive(`{
		"type": "button",
		"body": {
			"text": "Would you like to proceed?"
		},
		"action": {
			"buttons": [
				{
					"title": "Yes",
					"id": "yes"
				},
				{
					"title": "No",
					"id": "no"
				}
			]
		}
	}`)
	if err != nil {
		fmt.Println("Error creating interactive buttons:", err)
		return
	}

	// Send interactive message with quick reply buttons
	response, err := client.Messages.Create(plivo.MessageCreateParams{
		Src:       "source_number",
		Dst:       "destination_number",
		Type:      "whatsapp",
		Interactive: &interactive,
	})
	if err != nil {
		fmt.Println("Error sending interactive message:", err)
		return
	}

	fmt.Printf("Response: %#v\n", response)
}

Interactive Lists

Interactive lists allow you to present customers with a list of options.

Example:

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.Println("Error:", err)
		return
	}

	// Create an interactive list
	interactive, err := plivo.CreateWhatsappInteractive(`{
		"type": "list",
		"header": {
			"type": "text",
			"text": "Select an option"
		},
		"body": {
			"text": "Choose from the following options:"
		},
		"action": {
			"sections": [
				{
					"title": "Options",
					"rows": [
						{
							"id": "option1",
							"title": "Option 1",
							"description": "Description of option 1"
						},
						{
							"id": "option2",
							"title": "Option 2",
							"description": "Description of option 2"
						}
					]
				}
			]
		}
	}`)
	if err != nil {
		fmt.Println("Error creating interactive list:", err)
		return
	}

	// Send interactive message with list
	response, err := client.Messages.Create(plivo.MessageCreateParams{
		Src:       "source_number",
		Dst:       "destination_number",
		Type:      "whatsapp",
		Interactive: &interactive,
	})
	if err != nil {
		fmt.Println("Error sending interactive message:", err)
		return
	}

	fmt.Printf("Response: %#v\n", response)
}

Interactive CTA URLs

CTA URL messages allow you to send links and call-to-action buttons.

Example:

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.Println("Error:", err)
		return
	}

	// Create a CTA URL message
	interactive, err := plivo.CreateWhatsappInteractive(`{
		"type": "cta_url",
		"header": {
			"type": "media",
			"media": "https://example.com/image.jpg"
		},
		"body": {
			"text": "Check out this link!"
		},
		"footer": {
			"text": "Footer text"
		},
		"action": {
			"buttons": [
				{
					"title": "Visit Website",
					"url": "https://example.com"
				}
			]
		}
	}`)
	if err != nil {
		fmt.Println("Error creating CTA URL:", err)
		return
	}

	// Send interactive message with CTA URL
	response, err := client.Messages.Create(plivo.MessageCreateParams{
		Src:       "source_number",
		Dst:       "destination_number",
		Type:      "whatsapp",
		Interactive: &interactive,
	})
	if err != nil {
		fmt.Println("Error sending interactive message:", err)
		return
	}

	fmt.Printf("Response: %#v\n", response)
}

Location Messages

This guide shows how to send templated and non-templated location messages to recipients using Plivo’s APIs.

Templated Location Messages

Example:

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.Println("Error:", err)
		return
	}

	// Create a WhatsApp template
	template, err := plivo.CreateWhatsappTemplate(`{
        "name": "plivo_order_pickup",
        "language": "en_US",
        "components": [
            {
                "type": "header",
                "parameters": [
                    {
                        "type": "location",
                        "location": {
                            "latitude": "37.483307",
                            "longitude": "122.148981",
                            "name": "Pablo Morales",
                            "address": "1 Hacker Way, Menlo Park, CA 94025"
                        }
                    }
                ]
            }
        ]
    }`)
	if err != nil {
		fmt.Println("Error creating template:", err)
		return
	}

	// Send a templated message
	response, err := client.Messages.Create(plivo.MessageCreateParams{
		Src:     "source_number",
		Dst:     "destination_number",
		Type:    "whatsapp",
		Template: &template,
	})
	if err != nil {
		fmt.Println("Error sending message:", err)
		return
	}

	fmt.Printf("Response: %#v\n", response)
}

Non-Templated Location Messages

Example:

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.Println("Error:", err)
		return
	}

	// Create a WhatsApp location object
	location, err := plivo.CreateWhatsappLocation(`{
        "latitude": "37.483307",
        "longitude": "122.148981",
        "name": "Pablo Morales",
        "address": "1 Hacker Way, Menlo Park, CA 94025"
    }`)
	if err != nil {
		fmt.Println("Error creating location:", err)
		return
	}

	// Send a templated message
	response, err := client.Messages.Create(plivo.MessageCreateParams{
		Src:     "source_number",
		Dst:     "destination_number",
		Type:    "whatsapp",
		Location: &location,
	})
	if err != nil {
		fmt.Println("Error sending message:", err)
		return
	}

	fmt.Printf("Response: %#v\n", response)
}

More examples

Refer to the Plivo API Reference for more examples.

Local Development

Note: Requires latest versions of Docker & Docker-Compose. If you're on MacOS, ensure Docker Desktop is running.

Export the following environment variables in your host machine:

export PLIVO_AUTH_ID=<your_auth_id>
export PLIVO_AUTH_TOKEN=<your_auth_token>
export PLIVO_API_DEV_HOST=<plivoapi_dev_endpoint>
export PLIVO_API_PROD_HOST=<plivoapi_public_endpoint>

Run make build. This will create a docker container in which the sdk will be setup and dependencies will be installed.

The entrypoint of the docker container will be the setup_sdk.sh script. The script will handle all the necessary changes required for local development.

The above command will print the docker container id (and instructions to connect to it) to stdout.
The testing code can be added to <sdk_dir_path>/go-sdk-test/test.go in host
(or /usr/src/app/go-sdk-test/test.go in container)
The sdk directory will be mounted as a volume in the container. So any changes in the sdk code will also be reflected inside the container.
To run test code, run make run CONTAINER=<cont_id> in host.
To run unit tests, run make test CONTAINER=<cont_id> in host.

<cont_id> is the docker container id created in 2.
(The docker container should be running)

Test code and unit tests can also be run within the container using make run and make test respectively. (CONTAINER argument should be omitted when running from the container)

All .go source files should be in repository root

The .go files should not be nested in a plivo folder in the repository. Instead, all the .go files should be moved directly to the repository root in order for the project to follow go conventions.

Some issues caused by the code being nested in the plivo folder includes:

Godoc does not work: https://godoc.org/github.com/github.com/plivo/plivo-go/
Dependency management tools may not be able to import the code correctly.

Creating SMS not working

Hi, As of ~12am 11 Nov 2020, began experiencing an issue where any attempts to use client.Messages.Create returns an error: temporary failure. Everything was working as expected before that estimated time provided above.

Have tried sending SMS messages outside of this SDK via http client, and sms was sent successfully. Also, started a new project with the most basic code required to send sms:

package main

import (
	"github.com/plivo/plivo-go"
	"log"
)

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

	log.Println(resp, err)
}

and seeing this logged out: 2020/11/11 12:49:31 &{ [] } temporary failure

testutils.go always starts a new TestServer

This section here:

always starts a new TestServer, even in the context of a normal process.

This causes the process to fail on AppEngine as listening to a port is not allowed:

panic: httptest: failed to listen on a port: listen tcp6 [::1]:0: socket: operation not permitted

Unit test don't pass (and panics)

Tests that fail:

TestMedia_Get
TestMessageService_ListMedia

Also, tests in powerpack_test.go panics. Please remove calls to panic()
