We have a signup form on our website https://eyeli.com. When users submit the form, we receive an email. We then manually copy all the information from the email and post that to our backend using Postman.
We would like to change this for the form to post to the PHP backend and then for that to do a post to our REST API.
The reason we don't want to post directly from the web to our REST API is due to the security. We use basic authentication on the API and don't want to expose the token to the web.
