Bitly API Essential Guide

What type of API does Bitly provide?

Bitly API Type

Bitly has a REST API. This can be inferred from the following:

1. The Bitly developer documentation refers to "API endpoints", which is terminology commonly used with REST APIs.

2. There is no mention of GraphQL or SOAP in the Bitly API documentation.

3. The documentation structure and terminology (e.g. "Rate Limits", "Authentication") are typical of REST API documentation.

Key Characteristics of REST APIs

REST (Representational State Transfer) APIs have the following characteristics:

• They use standard HTTP methods like GET, POST, PUT, DELETE.
• Resources are accessed via URLs.
• They typically use JSON or XML for data formatting.
• They are stateless, meaning each request contains all the information needed to complete it.
• They are widely supported and relatively easy to use.

Does the Bitly API have webhooks?

Yes, the official Bitly API does have webhooks. Here are the key points about Bitly's webhook functionality:

Webhook Support

• Bitly offers webhooks that allow you to receive notifications when certain events occur.

Event Types

• Currently, the main event type you can subscribe to is "engagement". This includes:
  • Link clicks
  • QR code scans
  • Link-in-bio button clicks

Webhook Payload

The webhook payload includes information such as:

• Event ID
• Event type (engagement)
• Date and time of event
• Long URL that was redirected to
• Bitlink that was interacted with
• Country where the link was interacted with
• Referrer
• Device type
• Account and Group ID related to the link
• Tags associated with the link (optional)

Setting Up Webhooks

• You can configure webhooks through the Bitly web application or programmatically using webhook API endpoints.
• When setting up a webhook, you provide:
  • A name for the webhook
  • The endpoint URL where Bitly should send the payload
  • The groups the webhook applies to
  • Whether to activate it immediately
  • Whether to include tags in the payload

Authentication

• Bitly supports API Key, HTTP Basic Auth, and OAuth 2.0 client credentials grant for webhook authentication.

Error Handling

• Bitly will attempt to send a webhook payload up to 5 times if it fails.
• Webhooks that consistently fail will be put into an alert status and eventually deactivated if issues persist.

In summary, Bitly's webhook functionality allows you to receive real-time notifications about link engagements, providing valuable data for tracking and analytics purposes.

Rate Limits and other limitations

API Rate Limits of the Bitly API

The Bitly API implements rate limits to maintain efficiency, security, and performance. There are two main types of rate limits: platform limits and plan limits.

Platform Limits

Platform limits apply to all accounts regardless of the subscription plan:

• IP address limit: A maximum of five concurrent connections from a single IP address.
• Hourly limits: Rate limits reset once each hour and once each minute.
• Per-minute limit: One-tenth of the hourly limit. For example, if your limit for the /v4/shorten endpoint is 1,000 calls per hour, it will be limited to 100 calls per minute.

Plan Limits

Each Bitly account has monthly limits based on the subscription plan:

• Monthly API request limit: Each plan has a specific number of API requests allowed per month.
• Feature-specific limits: Plans have limits for short links, custom back-halves, redirects, and other features, which correspond to specific API endpoints.

Key Points to Consider

1. Rate limits reset at different intervals:

   • Platform limits: Reset hourly and minutely.
   • Plan limits: Reset on the first of each month.

2. Exceeding limits results in a 429 error:

   • 'RATE_LIMIT_EXCEEDED' for hourly or minutely limits.
   • 'API_USAGE_LIMIT_EXCEEDED' for monthly limits.

3. Limit information can be retrieved via API:

   • For platform limits: GET /v4/user/platform_limits
   • For plan limits: GET /v4/organizations/{organization_guid}/plan_limits

4. Increasing limits:

   • Platform limits: Requires a subscription to a custom enterprise-level account.
   • Plan limits: Requires upgrading to a higher plan or contacting an account manager.

Best Practices

1. Monitor your usage regularly to avoid hitting limits unexpectedly.
2. Implement proper error handling for 429 errors in your application.
3. If you need higher limits, consider upgrading your plan or contacting Bitly support.
4. When troubleshooting API limit issues with Bitly Support, provide detailed information about your API usage, endpoints used, and request volumes.

By understanding and adhering to these rate limits, you can ensure smooth integration with the Bitly API while maintaining optimal performance for your application.

Latest API Version

The most recent version of the Bitly API is version 4.0.0 (v4). Here are the key points to consider:

API Version

• The current version of the Bitly API is 4.0.0, also referred to as v4.

Key Features

• The Bitly API allows users to exercise the full power of their links through automated link customization, mobile deep linking, and click analytics.

• It provides functionality for shortening links, creating and distributing links at scale, and integrating Bitly into applications.

API Structure

• The API uses a RESTful structure with endpoints organized under the /v4 path.

• Common endpoints include /v4/user, /v4/organizations, /v4/groups, /v4/bitlinks, and /v4/shorten.

Authentication

• The API uses Bearer token authentication, which should be included in the Authorization header of requests.

Data Formats

• Requests and responses are typically in JSON format.

Best Practices

1. Always check the API documentation for the most up-to-date information on endpoints and parameters.
2. Use appropriate authentication methods and keep your API tokens secure.
3. Be aware of rate limits and implement proper error handling in your applications.
4. Familiarize yourself with Bitly-specific terms like Bitlinks (short links) and BSDs (Branded Short Domains).

Code Example

Here's a simple example of how to shorten a URL using the Bitly API v4:

import requests

api_endpoint = "https://api-ssl.bitly.com/v4/shorten"
access_token = "YOUR_ACCESS_TOKEN"

headers = {
    "Authorization": f"Bearer {access_token}",
    "Content-Type": "application/json"
}

data = {
    "long_url": "https://example.com",
    "domain": "bit.ly",
    "group_guid": "YOUR_GROUP_GUID"
}

response = requests.post(api_endpoint, json=data, headers=headers)

if response.status_code == 200:
    short_url = response.json()["link"]
    print(f"Shortened URL: {short_url}")
else:
    print(f"Error: {response.status_code} - {response.text}")

This example demonstrates how to use the /v4/shorten endpoint to create a shortened URL using the Bitly API v4.
