Good morning guys, greetings! I’m having problems when making a request of type POST in Java. This is the way I analyze the body: Gson gson = new Gson(); String bodyString = gson.toJson(address); **String to be encrypted for signature:** post/v1/addressesdvrbynoeyc1680606300rak\_886832C4E8581C1604C2rsk\_88f33b33fa5f45fb74c2902a180fe87423834672f1974c6d176bc706a392d79865e92f5a798c6b3a{“canton”:“”,“city”:“Anytown”,“country”:“US”,“district”:“”,“line\_1”:“123 State Street”,“line\_2”:“Apt. 34”,“line\_3”:“”,“metadata”:{“merchant\_defined”:true},“name”:“John Doe”,“phone\_number”:“12125559999”,“state”:“NY”,“zip”:“12345”} The JSON is valid ([https://jsonlint.com/](https://jsonlint.com/)) ![image](https://us1.discourse-cdn.com/flex016/uploads/rapyd/original/3X/b/3/b38f124868c2d89f26c5c40abdae441f38645e23.png) Is Sandbox enviroment Request URL: [https://sandboxapi.rapyd.net/v1/addresses](https://sandboxapi.rapyd.net/v1/addresses) Method: POST **Error** : 401 Unauthorized: [{“status”:{“error\_code”:“UNAUTHORIZED\_API\_CALL”,“status”:“ERROR”,“message”:“”,“response\_code”:“UNAUTHORIZED\_API\_CALL”,“operation\_id”:“72551f5d-7b3d-4781-a5c5-a05e6613438d”}}] Any idea what I may be doing wrong?

Hi @jcanare2 Regarding this specific error, it seems that you are sending a GET request, instead of a POST. That explains the UNAUTHORIZED\_API\_CALL error. Your client is hitting: `request: GET/v1/addresses` You have to send a POST request as documented here: > **[Rapyd Documentation](https://docs.rapyd.net/build-with-rapyd/reference/address#create-address)** > > Liberate global commerce with all the tools you need for payments, payouts, and business everywhere. Hope this helps! ---

Thanks, but, is not POST ? ![image](https://us1.discourse-cdn.com/flex016/uploads/rapyd/original/3X/0/c/0c34e38543631a80b5c055bce94371288f0f0459.png) ---

Hi @jcanare2 Yes, that is the string to calculate the signature. Thats seems correct. But the actual http request that you are sending to [https://sandboxapi.rapyd.net/v1/addresses](https://sandboxapi.rapyd.net/v1/addresses) is as GET request. You have to send a POST request to create an address. ---

Yes, indeed, it was the call I leave it here in case it helps someone: For Java Request Post Method: HttpEntity\ entity = new HttpEntity(bodyString, headers); restTemplate.postForObject(urlPathLarge, entity, Response.class); Thank you so much! ---
