Is there any way to integrate coinbase with java?

I was using below code to get the response but I Was getting the 403 error

URL url = new URL ("https://api.commerce.coinbase.com/checkouts");
        
 Map map=new HashMap();
       
 HttpURLConnection connection = (HttpURLConnection) url.openConnection();
 connection.setRequestMethod("POST");
 connection.setDoOutput(true);

From https://commerce.coinbase.com/docs/api/

> Most requests to the Commerce API must be authenticated with an API

You would need to provide minimal set of information to API in order for it to respond back with success code 200.

Yes, but it looks like you aren't providing enough information. There are two header fields that need to be supplied as well. These are X-CC-Api-Key which is your API key and X-CC-Version. See the link below.

https://commerce.coinbase.com/docs/api/#introduction

Header fields can be provided to HttpURLConnection using the addRequestProperty
https://docs.oracle.com/javase/8/docs/api/java/net/URLConnection.html#addRequestProperty-java.lang.String-java.lang.String-

URL url = new URL("https://api.commerce.coinbase.com/checkouts");

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.addRequestProperty("X-CC-Api-Key", "YourSuperFancyAPIKey");
connection.addRequestProperty("X-CC-Version", "2018-03-22");
connection.setDoOutput(true);

You also want to be careful about what method you use. You are supplying a POST method in your example. This probably not what you want to start with. If you send a GET method you will receive back a list of all checks. This will be a good place to start.

https://commerce.coinbase.com/docs/api/#checkouts

• GET to retrieve a list of checkouts
• POST to create a new checkout
• PUT to update a checkout
• DELETE to delete a checkout

This type of API is known as REST.
