Developer API & Webhooks

Everything in the dashboard, from your own code.

A REST API with consistent responses and human-readable errors. Send broadcasts, upload files, manage contacts, run SMS campaigns and Mailflows, connect Contact Center conversations and verify users, or trigger texts from any system with a webhook URL.

What you get

Built for the way you actually work

API keys you control

Create, view, copy, rotate and revoke. Rotating stops the old key immediately. Format: Authorization: Bearer zg_live_...

One response shape

Every reply is { success, data, error }. Branch on error.code, not on message text.

Idempotency keys

Retry safely. The same key never sends or charges twice.

Webhook messages

Create a webhook campaign with a sender name and message, and get a URL your store, CRM or booking app can call to trigger personalized texts.

Every product, one API

SMS Broadcast, CSV Broadcast, Campaigns, Mailflows, Contact Center (Organization accounts), Contacts and Imports, Sender Names, Voice OTP and Notifications.

How it works

Step by step

1
Create an API key
From the Developer page in the dashboard. Each organization member gets their own.
2
Send your first text
One POST with mobiles, message and sender_name. You get a batch ID and credits deducted.
3
Add an idempotency key
So retries after a timeout never double-send.
4
Automate with webhooks
Point your systems at a webhook URL to trigger texts without writing code inside our platform.

bash

curl -X POST https://api.sms-broadcast.smsphilippines.com/ \
  -H "Authorization: Bearer zg_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "mobiles": "639171234567,639181234567",
    "message": "Hi Juan, your order #2041 is ready for pickup.",
    "sender_name": "BAKERY"
  }'

# Response
{ "success": true, "data": { "batch_id": "9c2b…", "queued_count": 2, "credits_deducted": 2 }, "error": null }
