Voice API in Go: Code Example

Place a Call from Go

Call this from your server and keep the API key in an environment variable.

// Go standard library only.
body := strings.NewReader(`{"to":"+919876543210","from":"+918045678901",
  "text":"Hello from Edesy. Your order has shipped.",
  "status_callback":"https://your-app.com/webhooks/call-status"}`)
req, _ := http.NewRequest("POST", "https://voice-api.edesy.in/v1/calls", body)
req.Header.Set("Authorization", "Bearer "+os.Getenv("EDESY_API_KEY"))
req.Header.Set("Content-Type", "application/json")
resp, err := http.DefaultClient.Do(req)
if err != nil {
  log.Fatal(err)
}
defer resp.Body.Close()
out, _ := io.ReadAll(resp.Body)
fmt.Println(string(out)) // {"data":{"call_sid":...,"status":...},"meta":...}

Control the call with VoiceML

Instead of text, pass url: your endpoint returns VoiceML, a JSON list of instructions. It is not TwiML.

{
  "instructions": [
    { "verb": "say", "text": "Your order has shipped.", "language": "en-IN" },
    {
      "verb": "gather",
      "input": "dtmf",
      "num_digits": 1,
      "action": "https://your-app.com/voiceml/order",
      "nested": [{ "verb": "say", "text": "Press 1 to confirm, or 2 to cancel." }]
    }
  ]
}

Twilio-style request

The Twilio-shaped alias accepts Basic auth with your Account SID and Auth Token.

curl -X POST https://voice-api.edesy.in/v1/Accounts/$ACCOUNT_SID/Calls \
  -u "$ACCOUNT_SID:$AUTH_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"to":"+919876543210","from":"+918045678901","text":"Hello from Edesy."}'
