Changelogs.md Authentication: API Key & OAuth 2.0 (2026)

Authentication overview

Changelogs.md provides authentication mechanisms to secure programmatic access to its platform, enabling developers and automated systems to interact with changelog data. These protocols are designed to ensure that API requests are made by authorized entities, protecting the integrity and confidentiality of product update information. The primary methods supported are API keys for direct application integration and OAuth 2.0 for scenarios requiring user consent and delegated authorization. Understanding these methods is crucial for securely publishing product updates, managing release notes, and integrating Changelogs.md into existing workflows.

API keys offer a straightforward approach for server-side applications that require consistent access without user intervention. Conversely, OAuth 2.0 is suitable for client applications that act on behalf of a user, providing a secure way to grant limited access to user accounts without sharing credentials directly. Both methods are critical for maintaining the security posture of an application and adhering to best practices for API interactions. For detailed setup instructions, refer to the official Changelogs.md API authentication guide.

Supported authentication methods

Changelogs.md supports two primary authentication methods to accommodate different integration requirements:

• API Keys: These are unique alphanumeric strings used to authenticate requests made by applications or services to the Changelogs.md API. API keys authorize the application itself, suitable for backend services or scripts that publish changelog entries automatically.
• OAuth 2.0: This protocol enables applications to obtain limited access to a user's account on Changelogs.md without requiring the user to share their credentials. OAuth 2.0 is ideal for third-party applications or integrations where a user grants permission for an application to perform actions on their behalf, such as managing changelog content or retrieving project information. The OAuth 2.0 authorization framework is widely adopted across web services for secure delegated access.

Getting your credentials

Accessing the Changelogs.md API requires valid authentication credentials. The process for obtaining these credentials depends on the chosen authentication method.

For API Keys

1. Log in: Access your Changelogs.md account dashboard.
2. Navigate to Settings: Look for a section like 'API Keys' or 'Developer Settings' within your project settings.
3. Generate Key: Follow the prompts to generate a new API key. It's common practice to give your key a descriptive name to help with management.
4. Secure Storage: Once generated, store your API key securely. It's typically shown only once. If lost, you may need to revoke it and generate a new one.

For specific steps, consult the Changelogs.md API key management documentation.

For OAuth 2.0

Implementing OAuth 2.0 usually involves registering your application with Changelogs.md to obtain a Client ID and Client Secret. These credentials are used to initiate the authorization flow.

1. Register Application: In your Changelogs.md account dashboard, locate the 'Developer Applications' section. Register a new application, providing details such as Redirect URIs.
2. Obtain Client ID & Secret: Upon registration, Changelogs.md will issue a unique Client ID and Client Secret for your application.
3. Implement Authorization Flow: Your application will then guide users through the OAuth 2.0 authorization flow, which typically involves redirecting them to Changelogs.md for consent, and then receiving an authorization code that can be exchanged for an access token.

The Changelogs.md OAuth 2.0 guide provides comprehensive details on application registration and the authorization flow implementation.

Authenticated request example

Once you have obtained your credentials, you can use them to make authenticated requests to the Changelogs.md API. Here's an example using an API key in a curl command to list changelog entries. Note that the actual endpoint and request body may vary based on the specific API action you intend to perform.

curl -X GET \
  'https://api.changelogs.md/v1/projects/{project_id}/entries' \
  -H 'X-API-Key: YOUR_API_KEY' \
  -H 'Content-Type: application/json'

In this example:

• YOUR_API_KEY should be replaced with your actual API key.
• {project_id} should be replaced with the unique identifier of your Changelogs.md project.
• The X-API-Key header is the standard way to transmit an API key for Changelogs.md.

For OAuth 2.0, requests typically include an Authorization header with a Bearer token:

curl -X POST \
  'https://api.changelogs.md/v1/projects/{project_id}/entries' \
  -H 'Authorization: Bearer YOUR_ACCESS_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{ "title": "New Feature Release", "content": "We've added X, Y, and Z." }'

In this OAuth 2.0 example:

• YOUR_ACCESS_TOKEN is the token obtained after the user completes the OAuth 2.0 authorization flow.
• The Authorization: Bearer header is a common standard for sending OAuth access tokens in HTTP requests.

Always consult the Changelogs.md API Reference for specific endpoint details, required headers, and request body formats.

Security best practices

To ensure the security of your Changelogs.md integrations and protect your data, adhere to these best practices:

• API Key Management:
  • Secure Storage: Never hardcode API keys directly into your application's source code. Store them in environment variables, secret management services (e.g., AWS Secrets Manager, Google Secret Manager), or configuration files that are not committed to version control.
  • Access Control: Restrict access to API keys to only the necessary personnel and systems.
  • Rotation: Regularly rotate your API keys. If a key is compromised, revoke it immediately and generate a new one.
  • Least Privilege: If Changelogs.md offers scoped API keys (API keys with specific permissions), generate keys with only the minimum permissions required for each application.
• OAuth 2.0 Implementation:
  • Secure Redirect URIs: Ensure your registered redirect URIs are specific and use HTTPS. Avoid using wildcard URIs in production environments.
  • Client Secret Protection: Treat your Client Secret like a password. Do not expose it in client-side code or public repositories. Store it securely on your server.
  • Scope Limitation: Request only the necessary OAuth scopes from users. Over-requesting permissions increases the risk if your application is compromised.
  • Token Refresh: Implement secure token refresh mechanisms to obtain new access tokens without re-prompting the user for authorization, using refresh tokens securely.
• Network Security:
  • HTTPS Everywhere: Always use HTTPS for all communications with the Changelogs.md API to encrypt data in transit and prevent eavesdropping.
  • IP Whitelisting: If Changelogs.md supports it, restrict API access to a specific list of trusted IP addresses.
• Error Handling and Logging:
  • Avoid Exposing Sensitive Data: Configure your application to avoid logging or displaying sensitive information (like API keys or tokens) in error messages or public logs.
  • Monitor API Usage: Implement logging and monitoring for API interactions to detect unusual activity or potential misuse of credentials.
• Compliance: Ensure your integration adheres to relevant data protection regulations such as GDPR compliance requirements, especially if handling personal data through the API. Changelogs.md itself is GDPR compliant, as noted on its documentation platform.

Adhering to these practices minimizes security risks and helps maintain a robust and reliable integration with the Changelogs.md platform.
