Updating an existing short URL's slug

The instructions below demonstrate how to edit a slug (the "path" or the end part of a URL after the backslash “/” that identifies specific page or post) of an existing short URL. This user guide can be used to modify additional parameters (for more information please visit the following page: https://developers.short.io/reference/post_links-linkid).

To update an existing short link

Create a secret API key from the Integrations and API menu: https://app.short.io/settings/integrations/api-key
Get the ID of the short link which you want to edit:

In the Short.io Dashboard open the link for editing:

Copy the link ID from your browser's address bar:

Then you may need to install prerequisites for HTTP requests (if necessary, depending on your programming language and its version).
With the following code snippet examples you will be able to update a short link's slug:

📘
Please replace YOUR_PATH (the new slug to be applied), APIKEY and LINK_ID with the appropriate values.

<?php

$curl = curl_init();

curl_setopt_array($curl, [
  CURLOPT_URL => "https://api.short.io/links/<<link_id>>",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => json_encode([

import requests

url = "https://api.short.io/links/<<link_id>>"

payload = {
    "path": "<<path>>"
}
headers = {
    "accept": "application/json",
    "content-type": "application/json",
    "Authorization": "<<apiKey>>"
}

response = requests.post(url, json=payload, headers=headers)

print(response.text)

const url = 'https://api.short.io/links/<<link_id>>';
const options = {
  method: 'POST',
  headers: {
    accept: 'application/json',
    'content-type': 'application/json',
    Authorization: '<<apiKey>>'
  },
  body: JSON.stringify({skipQS: false, archived: false, path: '<<path>>'})
};

fetch(url, options)
  .then(res => res.json())
  .then(json => console.log(json))
  .catch(err => console.error(err));

HttpRequest request = HttpRequest.newBuilder()
    .uri(URI.create("https://api.short.io/links/<<link_id>>"))
    .header("accept", "application/json")
    .header("content-type", "application/json")
    .header("Authorization", "<<apiKey>>")
    .method("POST", HttpRequest.BodyPublishers.ofString("{\"skipQS\":false,\"archived\":false,\"path\":\"<<path>>\"}"))
    .build();
HttpResponse<String> response = HttpClient.newHttpClient().send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());

using System.Net.Http.Headers;
var client = new HttpClient();
var request = new HttpRequestMessage
{
    Method = HttpMethod.Post,
    RequestUri = new Uri("https://api.short.io/links/<<link_id>>"),
    Headers =
    {
        { "accept", "application/json" },
        { "Authorization", " <<apiKey>>" },
    },
    Content = new StringContent("{\"skipQS\":false,\"archived\":false,\"path\":\"<<path>>\"}")
    {
        Headers =
        {
            ContentType = new MediaTypeHeaderValue("application/json")
        }
    }
};
using (var response = await client.SendAsync(request))
{
    response.EnsureSuccessStatusCode();
    var body = await response.Content.ReadAsStringAsync();
    Console.WriteLine(body);
}

Review the JSON response which should resemble the following:

{
  originalURL: '<<long_url>>',
  path: '<<path>>',
  idString: '<<link_id>>',
  id: '<<link_id>>',
  shortURL: 'https://<<domain_name>>/<<path>>',
  secureShortURL: 'https://<<domain_name>>/<<path>>',
  cloaking: false,
  tags: [],
  createdAt: '2025-04-28T13:51:04.721Z',
  skipQS: false,
  archived: false,
  DomainId: <<domain_id>>,
  OwnerId: <<owner_id>>,
  hasPassword: false,
  source: 'api',
  User: {
    id: <<user_id>>,
    name: '<<user_name>>',
    email: '<<user_email>>',
    photoURL: '<<user_photo_id>>'
  }
}

You have successfully renamed a short link through our API:

Most important keys in the response are YOUR_PATH (the path or slug of the edited short link) and LINK_ID.
