How to Auto-Post an RSS Feed to Wix Blog (2026)

Updated: 2026-09-28

Short answer: create an API key in your Wix account with the Manage Blog permission, and add it to PostRSS together with your site ID under Accounts → Add new Wix Blog account. Then open Ziele → Add feed, choose Wix Blog in Target settings and add your feed under Add source (Type = RSS feed, Link = your feed address). Each new item is created and published as a Wix Blog post with an image, paragraphs and a link back to the original. Wix Blog is included from the Professional plan.

Wix is a site builder first and a blogging platform second, which is exactly why this comes up. Companies build a marketing site in Wix because it looks the way they want, then discover that keeping its blog current means somebody opening the Wix editor and retyping an article that already exists somewhere else. This guide is the long version; the auto-post RSS to Wix Blog page has the short one.

The two credentials, and where they come from

Wix needs two pieces of information, and people usually have trouble with the second one.

• An API key, created in your Wix account, carrying the Manage Blog permission. A key without that permission will connect and then fail when it tries to create a post, which is a confusing failure to debug if you do not know to look for it.
• Your site ID, because a Wix account can hold several sites and the key alone does not say which one you mean.

Both go into PostRSS together. The API key is a credential for your Wix account, so it belongs in the same category as a password: not in a shared document, not in a ticket, and revoked in Wix the moment it is no longer needed.

What arrives on the Wix blog

Each new feed item becomes a complete Wix Blog post rather than a link: the image, the text laid out in paragraphs, and a link back to the original article. It is published, not held as a draft.

That last detail is worth planning around. Because posts go live as they arrive, the quality of your feed is the quality of your blog. A feed shipping full text with a proper featured image produces posts that look deliberate; a summary-only feed produces a blog of stubs. If your source feed is set to excerpts, change that before you connect anything — it is a setting in your CMS, and it is the single biggest factor in how this looks.

The canonical question

If you are mirroring your own articles onto a Wix site, you are publishing the same text on two domains. Search engines resolve that by choosing one version to rank, and the choice may not be the one you want.

PostRSS includes a link back to the original in every post it creates, which is honest and useful for readers. If search performance on the original matters to you, it is worth checking what Wix lets you do about canonical tags on blog posts and treating the mirror as distribution rather than as a second place you expect to rank. For a Wix site that is the primary home of the content, none of this applies.

Who this actually helps

• A Wix marketing site with the blog elsewhere. Common when editorial runs on WordPress or Ghost but the design lives in Wix.
• Agencies running client sites. One feed per client, one Target each, no logging into a builder for every post.
• Multi-site publishers. The same feed can fill blogs on several Wix sites, each with its own key and site ID.
• Anyone migrating. Keeping a Wix blog alive while a move happens, without doing the work twice.

Setting it up, step by step

1. In your Wix account, create an API key with the Manage Blog permission, and find your site ID.
2. In PostRSS, open Accounts and choose Add new Wix Blog account. Paste the API key and the site ID.
3. Open Targets and click Add feed. One feed going to one destination is one Target.
4. In Target settings, choose Wix Blog and the account you just connected.
5. Click Add source. Set Type to RSS feed and paste your feed address into Link. Save.
6. Check the first item that arrives. PostRSS checks the feed every 5 minutes, and every minute on Enterprise plans.

PostRSS publishes items that appear in the feed after the Target starts running. It does not import the back catalogue — the alternative would be a destination flooded with years of archive on its first day.

Check the feed before you check the integration

When a destination goes quiet, the feed is usually the cause. Open the feed URL in a browser first.

• Has anything been published since you connected it? Only items that appear after the Target starts running are published.
• Is it full text or a summary? A summary-only feed produces thin posts, and no destination can restore text the feed never sent.
• Is there an image in the item? It has to be in the feed — in the item content or as an enclosure — not merely on the page the item links to.
• Are the links absolute? Relative URLs work on your site and break everywhere else.

All four are fixed in your content system.

Which plan includes it

Wix Blog is included from the Professional plan. Each destination you connect counts as one Target, and your plan decides how many Targets and how many posts a month you get. An annual subscription is cheaper than paying monthly. Current limits per tier are on the pricing page, and the full lineup of 66 networks is on the supported networks page. The Wix Blog page has the short version of the setup.

When posts stop appearing

• The key lacks the Manage Blog permission. It connects and then fails at post creation. Recreate the key with that permission.
• The wrong site ID. A Wix account can hold several sites; the key alone does not identify one.
• The key was revoked. API keys are managed in your Wix account and stop working the moment they are removed.
• Posts arrive without an image. The feed item has none. Check the raw feed before blaming the connection.

Frequently Asked Questions

Which Wix permission does the API key need?

Manage Blog. A key without it will connect successfully and then fail when PostRSS tries to create a post, which is the most common setup problem here.

Why does PostRSS need my site ID as well as the key?

Because a Wix account can contain more than one site, and the key alone does not say which blog the posts belong in.

Do items arrive as drafts?

No. Each new feed item is created and published as a Wix Blog post, so it is worth checking that your source feed carries full text and an image before connecting it.

Will the post include the article image?

Yes, when the feed item carries one. Items without an image produce posts without one — nothing can supply a picture the feed never sent.

Does this create duplicate content problems?

Publishing the same article on two domains is duplication, and search engines will pick one to rank. Every post links back to the original; if search performance on the original matters, treat the Wix copy as distribution rather than as a page you expect to rank.

Can one feed fill blogs on several Wix sites?

Yes. Each site is a separate Target with its own key and site ID, and the same feed can be a source for all of them.

Will connecting a feed import my archive?

No. Only items appearing after the Target starts running are published.

The bottom line

Wix Blog is a two-credential setup with one thing that catches people out: the API key must carry the Manage Blog permission, and you need the site ID as well. Get those right, make sure your source feed ships full text and an image, and a blog that used to be updated by hand updates itself. It is included from the Professional plan.
