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.
- Go >= 1.13.x
The steps described below uses go modules.
$ mkdir ~/helloplivo
$ cd ~/helloplivo
$ go mod init helloplivoThis will generate a go.mod and go.sum file.
$ go get github.com/plivo/plivo-go/v7To 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 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 timeUsing 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.
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!",
})
}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",
})
}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)
}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>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)
}Refer to the Plivo API Reference for more examples.
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.shscript. 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.goin host
(or/usr/src/app/go-sdk-test/test.goin 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 runandmake testrespectively. (CONTAINERargument should be omitted when running from the container)
