Get API key

App builder

Replit + SocialHelper

Give the app you’re building in Replit a share button: it calls the SocialHelper API from a server function, with your API key kept in Replit’s secrets.

Setup

Set it up in Replit.

About five minutes, from key to first post.

Source: Replit documentation ↗

  1. 1

    Create an API key

    In the SocialHelper dashboard, open Developers and create a key. It starts with sh_ and is shown once, so copy it somewhere safe.

  2. 2

    Store the key as a secret

    Add SOCIALHELPER_API_KEY in the Secrets tool; your server code reads it as process.env.SOCIALHELPER_API_KEY. Before you publish, check that it’s set under Publishing → Adjust settings → Production app secrets.

  3. 3

    Ask Replit to build the share function

    Paste this prompt into Replit:

    Add a “Share” button that posts the selected update to my social
accounts. Create a server-side function that sends POST
https://socialhelper.app/api/v1/posts with the header “Authorization:
Bearer ” followed by the secret SOCIALHELPER_API_KEY, and a JSON body
with “text” and “accounts”. Load the account IDs from GET
https://socialhelper.app/api/v1/accounts. Never put the API key in
client-side code.
  4. 4

    Check the function

    It should look roughly like this: the key comes from the secret, and the browser only ever talks to your function.

    // server.js (Node 20+ with Express and express.json())
// Protect this route so only you, or your signed-in users, can call it.
app.post("/api/share", async (req, res) => {
  const { text, accounts } = req.body;

  const response = await fetch("https://socialhelper.app/api/v1/posts", {
    method: "POST",
    headers: {
      Authorization: `Bearer ${process.env.SOCIALHELPER_API_KEY}`,
      "Content-Type": "application/json",
      "Idempotency-Key": crypto.randomUUID(),
    },
    body: JSON.stringify({ text, accounts }),
  });

  res.status(response.status).type("application/json").send(await response.text());
});

Ship it from Replit.
