Generating engaging social media captions with ChatGPT is already a staple for many content creators and social media managers. However, copying and pasting those drafts into a scheduling tool still takes extra time.

In this walkthrough, based on the tutorial video [How to post directly to social media from ChatGPT](https://www.youtube.com/watch?v=heZPGn_LkXw), we share how you can connect ChatGPT directly to OneUp — a social media scheduling platform — so you can draft, schedule, and publish posts directly inside your ChatGPT workflow.

## What You Need Before Starting

- **ChatGPT Account:** Access to custom plugins/MCP tools setup

- **OneUp Account:** A [OneUp](https://www.oneupapp.io) account to generate your API key and manage connected social profiles


## Step-by-Step Guide

### Step 1: Set Up the Custom Plugin in ChatGPT

1. Open ChatGPT and navigate to the **Plugins** menu.

2. Click the **+** icon to create a new custom plugin.

3. Name your plugin (e.g., `OneUp`).


### Step 2: Grab the OneUp MCP Connector URL

1. Log in to your OneUp account.

2. Open the **API Docs** and navigate to the OneUp MCP Connector setup page (under **ChatGPT Setup**).

3. Copy the setup URL provided in the documentation.

4. Paste the URL into your ChatGPT plugin configuration, leave authentication set to **OAuth**, and click **Create**.


### Step 3: Link Your OneUp API Key

1. Click **Sign In** on the newly created plugin popup.

2. In a separate tab, go to your OneUp dashboard, click the **Gear icon** in the dropdown menu, and select **API and MCP**.

3. Click **Generate API Key** and copy the resulting key.

4. Return to the authentication screen, paste your API key, and click **Authorize**. The tab will automatically close once the connection succeeds.


### Step 4: Adjust Plugin Permissions

To ensure seamless execution when ChatGPT posts on your behalf:

1. Go to **Installed Plugins** inside ChatGPT and locate your OneUp plugin.

2. Verify that it displays **Connected**.

3. Open **Permissions** and set the permission level to **Allow all actions** (this prevents ChatGPT from blocking scheduling workflows).


### Step 5: Draft and Schedule Posts via Prompt

Once connected, you can schedule posts natively through the chat window!

> **Example Prompt:**
>
> "Create a Facebook post with the caption 'Hello' to my testing Facebook page under the \[Category Name\] category for 3:00 PM today."

ChatGPT will trigger the OneUp connector and confirm once the post has been scheduled successfully. You can verify the post directly in your OneUp Calendar or account dashboard.

## Beyond Basic Scheduling

Integrating OneUp with ChatGPT isn't just limited to basic post-scheduling. You can also prompt ChatGPT to:

- Publish instantly or schedule ahead across multiple channels

- Fetch social media comments and generate replies directly inside ChatGPT

- Retrieve performance analytics and ask ChatGPT questions about your engagement trends to optimize your content strategy
