Manage API keys for secure programmatic access to LikeDo APIs
LikeDo DocsManage API keys for secure programmatic access to LikeDo APIs
API keys are your credentials for accessing LikeDo's Open API endpoints. They provide secure, programmatic access to create and manage short links, email addresses, and other resources without requiring interactive login.
When creating a new API key, you'll configure the following settings:
A descriptive name to help you identify the key's purpose.
Set how long the key remains valid.
Control the number of requests allowed per time window.

After creating your API key:
Use your API key to authenticate API requests in one of two ways:
Include the key in the Authorization header as a Bearer token:
Authorization: Bearer YOUR_API_KEYExample:
curl -X POST https://like.do/api/v1/links/create \
-H "Authorization: Bearer sk_live_abc123..." \
-H "Content-Type: application/json" \
-d '{"slug": "example", "targetUrl": "https://example.com"}'Pass the key as a URL query parameter:
?key=YOUR_API_KEYExample:
curl -X POST "https://like.do/api/v1/links/create?key=sk_live_abc123..." \
-H "Content-Type: application/json" \
-d '{"slug": "example", "targetUrl": "https://example.com"}'Rate limits protect our API infrastructure and ensure fair usage across all users. Limits are based on your subscription tier:
| Plan | Requests/Minute | Requests/Hour | Time Window |
|---|---|---|---|
| Free | 60 | 200 | 1 hour |
| Pro | 500 | 2000 | 1 hour |
| Lifetime | 500 | 2000 | 1 hour |
Every API response includes rate limit information in the headers:
X-RateLimit-Limit: 2000
X-RateLimit-Remaining: 1995
X-RateLimit-Reset: 1702123456When you exceed your rate limit, the API returns a 429 Too Many Requests response:
{
"success": false,
"error": "Rate limit exceeded. Please try again later."

Expires: 2026-03-07 10:30:00
Last used: 2025-12-07 15:45:00
Rate limit: 2000 requests per 1 hoursTo revoke access:
Warning: Applications using deleted keys will receive 401 Unauthorized errors immediately.
Store keys in environment variables or secure configuration:
.env file:
LIKEDO_API_KEY=sk_live_abc123...Usage in code:
const apiKey = process.env.LIKEDO_API_KEY;Separate keys for each environment:
dev_key_xyz...staging_key_abc...prod_key_123...// Using fetch with Authorization header
async function createShortLink(data) {
const response = await fetch('https://like.do/api/v1/links/create', {
method: 'POST',
headers: {
'Authorization': `Bearer ${process.env.LIKEDO_API_KEY}`
import os
import requests
def create_short_link(data):
"""Create a short link using the API key."""
api_key = os.environ.get('LIKEDO_API_KEY')
headers = {
'Authorization':
#!/bin/bash
# Store API key in environment variable
export LIKEDO_API_KEY="sk_live_abc123..."
# Create short link
curl -X POST https://like.do/api/v1/links/create \
-H "Authorization: Bearer $LIKEDO_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"slug": "my-link",
"targetUrl": "https://example.com"
}'<?php
function createShortLink($data) {
$apiKey = getenv('LIKEDO_API_KEY');
$ch = curl_init('https://like.do/api/v1/links/create');
curl_setopt_array($ch, [
