Api admin Rest - error Cors

We know that the admin REST API does not work on the frontend, but I have already developed practically all the custom registration within a register-custom.liquid file using fetch() with Javascript and I would not like to redo everything again. My question is, if I put these admin REST APIs in a backend (oceandigital) and generate a new route to be used on the frontend, will it work?

Note: the APIs used are client, client metafields and companies

Hi @regis.cuba

Yes, it will work.

@kyle_liu Great, so I don’t need to configure anything like a Shopify proxy app or anything like that, right?! Have you ever experienced this?? The only problem is that the new API will be exposed for anyone to use, right?! LOL

@regis.cuba
Yes, it will be available to everyone, you’ll need to do some validation for this situation
