Payhip is a digital-products store with a native blog, but its API only covers coupons and licences.
How Sorank connects: Sorank self-hosted blog. Payhip has no API endpoint to push articles into its own blog, so Sorank publishes and hosts the SEO articles on a Sorank-managed blog (your own subdomain or subfolder) that you link from your Payhip site, with full internal linking. You still get a fully automated, indexable blog without fighting Payhip's limitations.
Public API: Partial · Dedicated Make.com app: No · Create-blog-post endpoint: No · API docs: https://payhip.com/api-reference
