Adding A Record with API Not Working

I'm attempting to add an "A" record with the API but always get a 403 Access Denied.   

What's  confusing me is I'm able to get the list of records successfully through the API. 


Are there additional permissions or settings required to send Put or Patch commands to the API?


I've tried sending to both URLs



Any help is greatly appreciated!!

Normally, these types of requests needs credentials because you don't just anybody to add an A record on your DNS zones... The credentials can usually be passed via OAuth, post data or via headers... Some APIs allow using tokens in the url...  It all depends in the API... Check their documentations

Thank you for contacting API Support regarding the 403 Forbidden error you are receiving, as I understand, this only occurs for non-GET requests, so if you were POSTing, PATCHing, or PUTing. Would you happen to be using a RESTful application like Postman or RESTlet to make these requests? If you are, I think you are actually getting a 403 CORS Forbidden error.

I was able to add the specified 'testrecord' with your request.

1) make sure you are using Test keys in the Test environment ( and Prod keys in the Production environment (
2) make sure you are not mix matching keys and secrets, I'd go ahead and delete all keys and generate new ones
3) if you are using Postman, be sure to use the Native App for Postman and not the Chromium browser based app (the Chrome app is the one that gets the 403 CORS error, the Native app works just fine:
4) if you are still having an issue

add this custom header to your request:
"x-debug": "true"

make your request, get the error

then, inspect the response headers

Look for this header `X-Request-Id`
