This guide explains how to create an iOS Shortcut that uploads a Markdown file to a GitHub repository using the GitHub API.

---

Steps to Create the Shortcut

1. Prepare Your GitHub Personal Access Token

• Go to GitHub Developer Settings.
• Generate a Personal Access Token with the following permissions:
  • repo (for private repositories).
  • public_repo (for public repositories).
• Save the token securely, as it will be used in the Shortcut.

---

2. Create a New Shortcut

Open the Shortcuts app on your iPhone or iPad and follow these steps:

Step 1: Add Input (Markdown Content)

1. Use "Ask for Input" to get the Markdown file path and name:

   • Prompt: Enter file path (e.g., posts/article1.md).
   • Save this as a variable (e.g., FilePath).

2. Use "Get File" to select the Markdown content:

   • Use the File action to allow the user to pick a Markdown file.
   • Choose Open file and save its contents into a variable (e.g., MarkdownContent).

---

Step 2: Encode the Content in Base64

1. Add "Base64 Encode" action:

   • Input: MarkdownContent.
   • Save the Base64-encoded content as a variable (e.g., EncodedContent).

2. Add "Replace Text" to remove newlines (\n) from the encoded content:

   • Replace: \n.
   • With: (leave blank).
   • Save the result back to EncodedContent.

---

Step 3: Construct the GitHub API URL

1. Add a "Text" action:

   • Input:

    https://api.github.com/repos/{owner}/{repo}/contents/{FilePath}
   

• Replace {owner} with your GitHub username.
• Replace {repo} with your repository name.
• Replace {FilePath} with the variable FilePath.

1. Save the result as a variable (e.g., GitHubURL).

---

Step 4: Construct the Request Body

1. Add a "Dictionary" action:

   • Key: message → Value: Add new post.
   • Key: content → Value: EncodedContent.
   • Optional: Add branch → Value: main (if uploading to the main branch).

2. Save this dictionary as RequestBody.

---

Step 5: Send the Request to GitHub

1. Add a "Get Contents of URL" action:

   • Method: PUT.
   • URL: GitHubURL.
   • Headers:
     • Authorization: token YOUR_PERSONAL_ACCESS_TOKEN.
     • Content-Type: application/json.
   • Body: RequestBody.

2. Add error handling to check the response.

---

3. Test the Shortcut

Run the Shortcut:

1. Input the file path (e.g., posts/article1.md).
2. Select a Markdown file from your device.
3. The Shortcut will upload the file to the specified GitHub repository.

---

Troubleshooting

• Ensure your GitHub token has the correct permissions.
• Check the Base64-encoded content for unwanted line breaks.
• Verify the repository path and branch exist.
• Debug using the "Show Result" action to inspect variables at each step.

This Shortcut will dynamically handle file paths, encode content, and upload Markdown files directly to your GitHub repository.
