Putting a long URL directly into a text message costs you twice: it eats your byte budget, and you learn nothing about who clicked.

[Event] Autumn sale! https://shop.example.com/promotions/autumn-2026?utm_source=sms&utm_campaign=autumn
→ blows past 90 bytes into LMS pricing, and engagement is invisible.

[Event] Autumn sale! https://sendgo.io/s/k7Rm2xQ
→ fits in an SMS, and clicks are counted.

Creating a short link

POST /api/v2/short-urls

Field	Required	Notes
targetUrl	✅	Original URL. http/https only, up to 2,048 characters
title		A label for the management screen
expiresAt		After this, 410 Gone. Y-m-d H:i:s
forceNew		true issues a new code even for a URL already shortened

Node.js / TypeScript

const created = await sendgo.shortUrl.create({
  targetUrl: 'https://shop.example.com/promotions/autumn-2026',
  title: 'Autumn sale landing',
  expiresAt: '2026-09-30 23:59:59',
});

const { code, shortUrl } = created.data;

await sendgo.sms.sendSms({
  content: `[Event] Autumn sale! ${shortUrl}`,
  contacts: [{ contact: '01012345678' }],
});

Python

created = client.short_url.create(
    target_url="https://shop.example.com/promotions/autumn-2026",
    title="Autumn sale landing",
)
link = created["data"]["shortUrl"]

client.sms.send_sms(
    content=f"[Event] Autumn sale! {link}",
    contacts=[{"contact": "01012345678"}],
)

PHP

<?php

$short = $sendgo->shortUrl->create([
    'targetUrl' => 'https://shop.example.com/promotions/autumn-2026',
    'title'     => 'Autumn sale landing',
]);

$link = $short['data']['shortUrl'];

$sendgo->sms->sendSms([
    'content'  => "[Event] Autumn sale! {$link}",
    'contacts' => [['contact' => '01012345678']],
]);

Reading click statistics

const stats = await sendgo.shortUrl.stats(code, { from: '2026-09-01' });

await sendgo.shortUrl.list({ count: 10 });   // list
await sendgo.shortUrl.show(code);            // detail
await sendgo.shortUrl.deactivate(code);      // stop redirecting, keep the stats

stats = client.short_url.stats(code, from_="2026-09-01")
client.short_url.list(count=10)
client.short_url.show(code)

<?php

$stats = $sendgo->shortUrl->stats($code, ['from' => '2026-09-01']);
$sendgo->shortUrl->list(['count' => 10]);
$sendgo->shortUrl->show($code);
$sendgo->shortUrl->deactivate($code);

Separate statistics per campaign

If several campaigns point at the same landing page, use forceNew to get distinct codes. Otherwise the numbers merge and you cannot tell which campaign worked.

const augustLink = await sendgo.shortUrl.create({
  targetUrl: 'https://shop.example.com/sale',
  title: 'August sale - Alimtalk',
  forceNew: true,
});

const septemberLink = await sendgo.shortUrl.create({
  targetUrl: 'https://shop.example.com/sale',   // same destination
  title: 'September sale - SMS',
  forceNew: true,                                // different code
});

Easy to get wrong

• Put the link in a template variable, not the Alimtalk template body. Hard-coding a URL in the template means re-review for every campaign. Pass the short link through #{var3} instead.
• Set an expiry. A live link to a finished event sends late clickers to a dead page.
• Do not put short links in your sitemap. For some links the unguessable code is the access control.
