Shopify has a real, supported Article API under /admin/api/{version}/blogs/{blog_id}/articles.json. Articles created this way appear at /blogs/{blog-handle}/{article-handle}, exactly like ones authored in the Shopify admin.

What you need

• A Shopify store (any plan).
• Admin access to create a custom app.

Setup

1. Shopify admin → Settings → Apps and sales channels → Develop apps.
2. Click Create an app, name it "Mentionwell".
3. Configure Admin API scopes:
   • read_content
   • write_content
4. Install app → reveal the Admin API access token. Copy it (Shopify shows it once).
5. Decide which Blog the articles should land in. Most stores have a default "News" blog. To list your blogs, you can hit:

   GET https://{shop}.myshopify.com/admin/api/2024-10/blogs.json
   

   Or just create a new one in Shopify admin → Online Store → Blog posts → Manage blogs.
6. Paste the shop URL, the admin token, and the target blog ID into Mentionwell.

What gets pushed

Mentionwell field	Shopify Article
Title	title
Slug	handle (lowercase, hyphenated)
Excerpt	summary_html (shown on blog index)
HTML body	body_html
Featured image	image.src (Shopify mirrors it to its CDN)
Tags	comma-separated string in tags
Author	author (free-text)
Published date	published_at + published: true
SEO title/description	metafields global.title_tag / global.description_tag
JSON-LD	inline <script type="application/ld+json"> inside body_html

Caveats

• No real categories. Shopify's only category-like concept is "which Blog the article lives in." If you want top-level taxonomy, create multiple Blogs (e.g. news, guides, how-to) and let Mentionwell choose per article.
• Tags are flat strings. Mentionwell joins your tags with commas before pushing.
• Rate limits. Shopify's leaky bucket allows ~2 requests/sec sustained on most plans (4/sec on Plus). Mentionwell's worker honours Retry-After and slows down automatically.
• HTML allowed tags. Shopify strips inline event handlers and most non-LD <script> tags. JSON-LD specifically is allowed; Mentionwell includes it in body_html.

Common failures

• 401 — wrong access token, or pasted into the wrong field.
• 403 — missing write_content scope. Open the custom app in Shopify, add the scope, and reinstall (scopes don't update on existing installs).
• 422 — invalid handle (must match [a-z0-9-]+) or a duplicate handle in the same blog. Mentionwell auto-suffixes on retry.
• 429 — rate-limited. Mentionwell retries with the Retry-After value automatically.
