How to Set Up Your X API Credentials

Follow these steps to connect your X/Twitter account to Threadify so you can post threads directly.

Before You Start

You need an X (Twitter) account
The X Developer Portal is free to use (Free tier allows 1,500 tweets/month)
The entire setup takes about 5 minutes

Create a Developer Account

Go to the X Developer Portal and sign in with your X account.

If this is your first time, you'll be asked to agree to the developer terms. Select the Free tier — it's all you need for posting threads.

Create a Project and App

In the Developer Portal dashboard, click Projects & Apps in the left sidebar.

Click + Add Project. Give it any name (e.g., "Threadify Posting"). Then create an App within that project — name it anything you like.

Set Up User Authentication

Click into your App, then go to the Settings tab.

Scroll down to User authentication settings and click Set up (or Edit if already configured).

Set these values:

App permissions: Select Read and write
Type of App: Select Web App, Automated App or Bot
Callback URI: Enter https://example.com/callback
Website URL: Enter any URL (e.g., https://example.com)

Click Save.

Important: You MUST set permissions to "Read and write" BEFORE generating your Access Token. If you change permissions later, you'll need to regenerate the tokens.

Get Your API Key and Secret

Go to the Keys and tokens tab in your App.

Under Consumer Keys, you'll see your API Key and API Key Secret. If they're not visible, click Regenerate to create new ones.

Copy both values — you'll need them in a moment.

Generate Your Access Token and Secret

On the same Keys and tokens page, scroll down to the Authentication Tokens section.

Click Generate next to Access Token and Secret.

Copy the Access Token (starts with a number like 123456789-...) and the Access Token Secret.

Tip: The Access Token is tied to YOUR X account. Whoever's Access Token is used, that's the account the threads will be posted from.

Paste Into Threadify

Go back to the in Threadify and paste all four values:

API Key (Consumer Key)
API Key Secret (Consumer Secret)
Access Token
Access Token Secret

Click Save & Connect. Threadify will validate the credentials by checking your X account. If successful, you'll see your @username confirmed.

Troubleshooting

Getting a 401 Unauthorized error?

This usually means your Access Token was generated before you set "Read and write" permissions. Go back to Step 3, verify the permissions, then regenerate your Access Token and Secret in Step 5.

Getting a 403 Forbidden error?

Your app permissions are set to "Read only." Go to Settings → User authentication settings → change to "Read and write" → Save → then regenerate your Access Token and Secret.

Can't find the Keys and Tokens tab?

Make sure you're looking at your App (not the Project). In the left sidebar, click Projects & Apps → your project name → your app name. The tabs should appear at the top.
