Reactjs ajax request cross origin handling

I'm getting mirriad of errors trying to do an ajax call in a reactjs app using axios. I have an api that lives at a subdomain and making calls from the main domain.


Header add Access-Control-Allow-Origin: "*"
Header add Access-Control-Allow-Credentials: "true"
Header add Access-Control-Allow-Methods: "GET,HEAD,OPTIONS,POST,PUT"
Header add Access-Control-Allow-Headers: "Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers"

ajax headers in reactjs (using axios):

var options = {
            method: 'GET',
            url: '',
            headers: {
                'Access-Control-Allow-Origin': '*',
                'Access-Control-Allow-Methods': 'GET,HEAD,OPTIONS,POST,PUT',
                'Access-Control-Allow-Headers': 'Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers'

I've tried making changes to each of these but get different errors. If I have the Header add Access-Control-Allow-Origin: "*" it complains about double origins. If I remove it I I get an error about Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers in preflight response other changes has responded with Access-Control-Allow-Headers is not allowed by Access-Control-Allow-Headers in preflight response

I'm using wordpress as a headless CMS and tapping into the restful api to pull the data I need. I have noticed if I removed all of this I can get my data fine but I can't post without fixing the cross domain issues.
