I am getting invalid auth code when trying to get access token

Hi, i am trying to create a drop-shipping website with wix. I have successfully fetched the items, so i need access to wix store api

I have followed the steps in Authentication | REST API Reference | Wix.com

I have been trying to get access token so as to validate my request. I am getting an “invalid auth code”.

Thanks

Hi, I do “refresh_token” and I get “access_token” and web.postman.co announces:
Error: Header “Authorization” contains invalid characters

And wget: Request Header Fields Too Large

Please open your own post and describe your issue in detail.

OK.

Better?
