Get API key

App builder

v0 + SocialHelper

Give the app you’re building in v0 a share button: it calls the SocialHelper API from a server function, with your API key kept in v0’s secrets.

Setup

Set it up in v0.

About five minutes, from key to first post.

Source: v0 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 as an environment variable on the linked Vercel project. Choose the Encrypted type, not Sensitive: v0 can’t read sensitive variables.

  3. 3

    Ask v0 to build the share function

    Paste this prompt into v0:

    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.

    // app/api/share/route.ts (a Next.js route handler)
// Protect this route so only you, or your signed-in users, can call it.
export async function POST(request: Request) {
  const { text, accounts } = await request.json();

  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 }),
  });

  return new Response(await response.text(), {
    status: response.status,
    headers: { "Content-Type": "application/json" },
  });
}

Ship it from v0.
