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);

Answer

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.

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.

• 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.
