@w4rner Yes, you’d be adapting my WP recipe for use with your paid m.b. account. I suspect the generic URL would be remedied by the unique token. You might be able to generate an app token in your account settings that should work. If it doesn’t then ping Manton when you get a chance to see if he can make a recommendation.
The goal is to own and display your data from a website that you control, so just piping in your RSS feed into the micro.blog timeline isn’t the answer, since there’s no way to get it back out. Because you can’t control the code running on Micro.blog, you may have some kinks to work out to get things to display exactly the way you want them to, but I suspect Manton could help you there, espcially if it’s the sort of feature that others are bound to want.
