Key Features of the Contact API

Contact Retrieval

The primary function of the Contact API is to retrieve information about users within the Telegram network. The most common endpoint used for this purpose is GET contacts.

How to Retrieve Contacts

To get a list of all user contacts, you can send a GET request to:

https://api.telegram.org/bot<API_TOKEN>/contacts

Replace <API_TOKEN> with your actual bot token. The response will be in JSON format, containing details such as the username, first name, last name, etc., of each contacted user.

Example Request and Response

Here's a sample request followed by its corresponding response:

GET /bot12345/contacts HTTP/1.1
Host: api.telegram.org
Authorization: Bearer <YOUR_API_TOKEN>
{
  "ok": true,
  "result": [
    {
      "username": "@john_doe",
      "first_name": "John",
      "last_name": "Doe"
    },
    {
      "username": "@jane_smith",
      "first_name": "Jane",
      "last_name": "Smith"
    }
  ]
}

Address Management

Address management is another critical aspect of the Contact API, allowing users to update and delete addresses associated with their profiles.

Updating User Addresses

To add new addresses or update existing ones, you need to post data using the following URL:

https://api.telegram.org/bot<API_TOKEN>/setMyAddress

Replace <API_TOKEN> with your bot token. Your request body should include fields like address, city, country, and others relevant to address information.

Example Request

POST /bot12345/setMyAddress HTTP/1.1
Host: api.telegram.org
Authorization: Bearer <YOUR_API_TOKEN>
Content-Type: application/json
{
  "address": "New York City, NY",
  "city": "New York",
  "country": "USA"
}

Removing Unused Addresses

Deleting inactive addresses ensures that your database remains clean and efficient. To remove unused addresses, simply send a DELETE request to:

https://api.telegram.org/bot<API_TOKEN>/deleteMyAddress

Again, replace <API_TOKEN> with your bot token. This action removes any address entries related to the current user from the system.

Best Practices for Using the Contact API

When working with the Contact API, several best practices help ensure smooth operation and security:

Security Considerations

• Token Authentication: Always use secure tokens (e.g., OAuth) when making requests to protect against unauthorized access.
• Handling Unauthorized Requests: If a request fails due to lack of permissions, respond appropriately rather than returning error messages directly.

Performance Optimization

• Efficient Data Retrieval Techniques: Utilize pagination and limit responses to avoid overwhelming resources.
• Implementing Caching Mechanisms: Cache frequently accessed data to reduce latency and improve performance.

Troubleshooting Common Issues

If you encounter issues while interacting with the Contact API, here are some troubleshooting tips:

Error Handling

• Identify Common Errors: Check if errors match known patterns (e.g., invalid credentials).
• Solutions for Specific Issues: Refer to documentation or seek community support forums for tailored solutions.
