You can build a social feed aggregator (also known as a social wall) that works without writing code. Point a vibe-coding tool like Lovable, Replit, Bolt, or v0 using the Walls.io social media API, describe what you want in one clear prompt, and it generates the whole app: pulling your aggregated posts, storing your token safely, and rendering a live feed. Here’s the prompt and some information about each tool.
If you would rather write the code yourself, we have a developer guide to the Walls.io API with PHP and JavaScript. This one is for people who would rather describe the result and let the tool build it.
Think of a social feed as one screen that collects posts from numerous networks and shows them together, live. New to the idea? This article explains what a social media wall actually is in more detail. Three situations account for most of the walls people build.
At events, a social media feed on a big screen turns the audience into the show. Attendee posts, photos, and hashtags scroll past; people see themselves up there, and they post more. If that is your case, there are plenty of ideas for how to run social media at your event.
On a website, the same feed becomes a widget on your homepage or a campaign page, keeping the page alive with user-generated content that refreshes itself. And on digital signage, the wall runs on screens in a shop, a lobby, or a stadium. One feed, many screens, and you decide how each one looks. Browsing a few real social wall examples is the fastest way to picture it.
No matter where the show is set, the work behind the scenes is always the same. It’s annoying, but it’s also essential: collecting good content from many different platforms at once. A social media API that is built for aggregation is what makes that disappear.
Why is one aggregation API simpler than juggling many?
It’s a mistake to set up networks one by one. Each platform has its own way of getting you logged in, its own way of storing data, and its own way of getting approval. All of a sudden, you might find yourself having to deal with a whole new set of challenges. If you do it yourself, you’ll oversee a bunch of different integrations, and you’ll have to keep fixing them every time the network changes the rules.
Walls.io flips that around by acting as a single Meta-API. You connect once and get social media aggregation – get content from social media and show it anywhere, on any supported network, in the same format. Since the fields are already organized, a post from any network looks the same to your app. This means that a vibe-coding tool only has to learn one shape. You can add or remove sources from your Walls.io settings, not from the app itself.
This last point is especially important for vibe coding. The less the tool has to think about, the better it works. One clean endpoint and one data shape are about as simple as an app can get. Start a free trial, then come back and run the prompt.
Start your Walls.io social media feed trial and get your API key
Where do you find your Walls.io API access token?
You will need one thing before the tool can fetch anything: an access token, which ties each request to your wall. Head to the Walls.io dashboard, open your feed’s settings, go to the API section, and hit Activate API access. The token appears there for you to copy.
That token comes from API Access – use a single API to integrate and manage content from multiple networks and platforms – which is part of every paid Walls.io plan. The pricing page shows which tier you need, and the API docs on GitHub have the full details if you ever want them. Keep the token nearby because you’ll need to paste it into your tool’s secrets area later, not the app itself.
This is the part that does the work. The prompt below is written in simple language and works in Lovable, Replit, Bolt and v0. Paste it in, and when the tool asks for your Walls.io token, add it through its secrets or environment settings rather than typing it into the app.
Build a web app that displays a live "social wall": a responsive grid of
social media posts aggregated by Walls.io.
Where the data comes from
- Use the Walls.io API. Read the docs first so you use the real endpoint
and field names: https://github.com/DieSocialisten/Walls.io-API-Docs
- Fetch posts from GET https://api.walls.io/v1/posts using my access token.
Keep my token safe (this part is important)
- Store my Walls.io access token as a backend secret / environment
variable. Never put it in the frontend or in any client-side code.
- The Walls.io API does not allow browser (CORS) requests, so make the
call from a server function or backend route, not from the browser.
The browser should only ever talk to my own backend, never to Walls.io
directly.
What to fetch
- Request only these fields: id, type, comment, external_fullname,
userlink, post_image_cdn, external_image_cdn, permalink,
created_timestamp.
- Get the 24 newest posts and sort by -created_timestamp. (The API's
default order is by arrival time, not post date, so set this
explicitly or the order will look wrong.)
Keep it fast and reliable
- Cache the API response for about 5 minutes instead of calling on every
page load. This stays well within the rate limit.
- If a request fails, show the last cached posts so the wall never goes
blank.
- Refresh the wall in the background every few minutes so new posts
appear without a manual reload.
How it should look
- A clean, modern, responsive card grid. Each card shows the author name
(external_fullname), the image (post_image_cdn, falling back to
external_image_cdn, and no image if neither exists), the post text
(comment), and a link to the original post (permalink).
- Make it look good on a large screen or TV as well as on mobile, since
this may run on a display at an event.
- Sanitize post text so nothing in a post can break the layout or inject
markup.
When you are done, tell me exactly where to paste my Walls.io access
token and how to publish the app.
Two small habits make the result much better. First, if the tool offers a plan or preview step before it builds, read it and confirm that the token is going into a backend secret. Second, make small changes to the site after it’s up and running. For example, you could make the cards larger for a TV screen or group posts into a masonry layout. Don’t ask for everything at once.
Which vibe-coding tool fits you best?
All four will build this social media aggregator. The main differences are in how much they design for you, how they host the result, and how they handle your token. Here are some things to keep in mind for each.
Lovable
Lovable turns a prompt into a full-stack app. It generates React with Tailwind and shadcn/ui on the front, and a backend through Lovable Cloud (built on Supabase) with edge functions and a proper secrets manager. That secrets manager is precisely where your Walls.io token should go. It stays backend-only and gets injected into the edge function that calls the API, so it never reaches the browser. Use Plan Mode to check the approach before it writes anything, and Visual Edits to make small changes to the card design by clicking instead of typing. The most important thing to check is that the fetch runs in an edge function, not a client-side function.
Replit
Replit and its agent are the most independent of the four. The Agent builds, runs, hosts, and deploys the app in your browser. It also comes with a secrets manager for environment variables and a long list of built-in integrations. Run the Agent with the prompt, put your token into Replit Secrets instead of the code, and let it deploy on Replit’s own hosting. The Agent happily adds a backend and runs commands, so it handles the “call the API from the server” requirement well. But let’s say it explicitly anyway. Its checkpoints let you roll back cleanly if a change goes wrong.
Bolt
Bolt (from StackBlitz) is a tool that allows you to run a full-stack project entirely in the browser using WebContainers. This makes it the fastest way to create a shareable prototype. This is handy when you want to show a demo to your colleagues by sending them a link. Bolt Cloud provides hosting, a database, and authentication. You can also use Netlify to deploy the frontend. Put your token in an environment variable and have Bolt add a small server route for the fetch. Do not let it call Walls.io from the client. One good thing about its in-browser IDE is that you can see the generated code, so it’s easy to check where the token is used.
v0
v0, Vercel’s builder, is the best choice when appearance is key. It produces React and Next.js interfaces with Shadcn/UI and Tailwind, has grown into full-stack territory, deploys straight to Vercel, and even runs an automatic security scan that flags exposed environment variables and unsafe API calls. Store your Walls.io token as a Vercel environment variable. Then, v0 can fetch it from a Next.js API route or a server component. This keeps the key on the server. Focus on making it look good first, then connect the data.
Others worth a look
The same prompt works in other builders too. Base44 and Mocha are good options for hosting without a lot of technical knowledge, and Figma Make is worth a try if you already use Figma. No matter what you choose, the token rule remains the same: the token belongs in a secret on the backend, and the API call belongs on the server.
Keep your token off the front end
One warning applies to all of these tools. Vibe-coding tools are built to produce something that runs, which is not the same as something that is safe. Veracode’s research found that almost half of the AI-generated code samples had known security problems. There have also been many cases of vibe-coded apps leaking secrets or leaving data unprotected. The solution for a social feed wall is simple: add your Walls.io token to the backend secret, and make the API call on the server, not the browser. The prompt above already asks for this. Leave that instruction in, and look at the result before you publish it to a public screen.
The appeal of this route is clear and straightforward. You can create a live social feed in just an afternoon. You can shape the design by talking to the tool. You only need one integration instead of a dozen. The trade-offs are equally honest: you need a paid Walls.io plan, you lean on both Walls.io and your builder for uptime, and you should check the security before it goes live. For most projects related to events, websites, and signage, that is an easy decision.
Grab your token, paste the prompt into the tool you like best, and you can have a wall running today. Start your free trial and point your vibe-coding tool at the Walls.io API docs.
