So my skill will use account linking in order for me to get a string a user enters in on my custom login screen. So my current process I'm trying to make work is:
1. User begins linking process and gets take to my custom login screen.
2. They click 'Login using Amazon' which uses Amazon security profiles for logging in and then returns an access token.
3. The user is returned to my custom login screen after logging into their amazon account - in which they can enter a string into a textbox which I plan on sending (along with the access token given by amazon) to the alexa skill to save for later use in the actual skill.
4. They click complete and I redirect them to my skills implicit grant redirect url
So I am at the fourth hurdle here, and just keep getting the delightful;
Unable to link your Skill.
Please try again later.
And I haven't even worked out how I'm going to get this string across... so I guess why isn't the final bit working when i redirect to my skills redirect url and is it even possible to do what I want regarding sending a string over using account linking?
Thank you so much for any time :) Oh and below is an example of the redirect back to my alexa skills redirect url:
