CLOVA OCR VM proxy linkage guide

CLOVA OCR VM proxy linkage guide

Linkage with API Gateway is required in the process of using the CLOVA OCR product.
The VM proxy linkage guide provides information on the IP to be managed with the whitelist for the use of the CLOVA OCR product within the company's internal network, or information for controlling it through the API Gateway invoke URL.
In addition, the guide describes how to avoid exposing the secret key for calling the CLOVA OCR product.

NAVER Cloud Platform recommends the method of linking and calling the CLOVA OCR VM proxy through the process below.

You can configure it as shown below.

Create VM

        rewrite ^/ocrproxy/(.*)$ break;
        proxy_pass {your api gw Invoke url};
