    3. Open your terminal, navigate to the directory where you want to clone the repository, and run the following command:

      git clone <copied-url>
  4. Navigate to the directory of the cloned repository in your terminal and run composer install.

cd zotero-notification # or whatever the name of the extracted folder is
composer install
  • If you don't have composer installed, you can download it from here.

Creating the .env file

  1. In the public_html folder of your 000webhost site, create a new file named .env.
  2. Open the .env file and set your environment variables in the format VARIABLE_NAME=value. For example:
ZOTERO_API="your_zotero_api_key"
ZOTERO_USERID="your_zotero_user_id"
SENDGRID_API_KEY="your_sendgrid_api_key"
FROM_EMAIL="your_email_address"
TO_EMAIL="the_email_address_to_send_notifications_to"
  • Change the FROM_EMAIL and TO_EMAIL values to the email addresses you want to send the notifications from and to, respectively.

Getting the Zotero API Key & User ID

  1. When logged in to your Zotero account, navigate to the "Settings" section in the topbar menu, and then "Feeds/API" to create a new API key.
  2. You can find your userID in this section itself. Copy the userID and paste it into your .env file as the value for ZOTERO_USERID.
  3. Click "Create new private key" (API key), give description and set the permissions and save the key. Finally, copy it into your .env file as the value for ZOTERO_API_KEY.

Getting the SendGrid API Key

  1. Sign up for a free account on SendGrid.

  2. After logging in, navigate to the "Sender Authentication" section in the left-hand menu, and then "Verify a Single Sender" to create a new sender using your email address from which you want to send the notifications.

  3. After verification, navigate to the "Email API" section in the left-hand menu.

  4. Click on "Integration Guide".

  5. Choose "Web API" as your email send method and click on "Next" to choose PHP as your preferred language".

  6. Give your API key a name, and click on "Create Key".

  7. Copy the API key and paste it into your .env file as the value for SENDGRID_API_KEY.

Remember to keep your API key secure and do not share it with anyone.

Setting up GitHub Actions

  1. In your GitHub repository, navigate to the "Actions" tab.

  2. Click on "New workflow".

  3. Click on "set up a workflow yourself".

  4. Paste the following YAML script into the editor:

name: Scheduled Workflow
on:
  schedule:
    - cron: '0 */3 * * *' # runs every 3 hours
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Run a one-line script
      run: curl https://zotero-notify.000webhostapp.com/index.php
  1. Click on "Commit changes".

  2. Enter a commit message, choose to commit directly to the main branch and hit "Commit changes" again.

Limitations

  1. The free plan of Zotero offers 300 MB of storage and if you are out of storage, you will not be able to sync your library, and eventually, the script will not be able to fetch the latest updates.
    • So, if you have more than 300 MB of stored data, you will have to upgrade to a paid plan.
    • If you don't want to upgrade, a way to get around this is to simply remove annotated PDFs after reading and and linking a hosted version of the file from google drive or dropbox.
  2. Google can mark the email as spam. So, you may have to check your spam folder for the notifications and set the email address as "not spam" to receive the notifications in your inbox.
