I faced one issue related to cors some days back. When hitting an api with axios, I was getting <No Access-Control-Allow-Origin> header present on the server but I was able to make a successful call when hitting it with anchor tag. Any idea why??

Update: Access-Control-Allow-Origin is a response header - so in order to enable CORS - you need to add this header to the response from your server.

headers: {"Access-Control-Allow-Origin": "\*"}

kindly add the above line, check it once

[Sumanth S](https://hashnode.com/@SumanthS) Yes I know tthe point that this header is required to enable CORS. But, It is a third party api and they have not added this header I guess. But how am I able to access it with anchor tag then??
