SFTP Setup for Google Merchant Center

1. Log in to Google Merchant Center
2. Click the Settings icon (gear)
3. Select SFTP and Google Cloud Storage

In the SFTP section:

1. Click Generate to create SFTP credentials
2. Note your Username (format: {merchant_id}@{merchant_id}.sftp.googleproductfeed.com)
3. Set and save your Password

Important: Save your password immediately—Google won't show it again.

Location: Magmodules → Google Shopping - Feed → Automation and Google Merchant SFTP Transfer

After saving:

1. Generate a feed manually or via CLI
2. Check if the file was uploaded to Merchant Center
3. Verify in Products → Data sources that the feed was received

For automatic uploads, enable cron-based feed generation:

With both cron and SFTP enabled:

1. Cron generates fresh feed on schedule
2. Extension automatically uploads via SFTP
3. Google processes the new data

Symptoms: SFTP upload fails, connection errors in logs.

Check:

1. Credentials correct? Copy-paste from Merchant Center to avoid typos
2. Password expired? Regenerate in Merchant Center if needed
3. Firewall blocking? Ensure outbound connections to sftp.googleproductfeed.com:19321 are allowed

Symptoms: "Authentication failed" in logs.

Solutions:

1. Regenerate credentials in Merchant Center
2. Update credentials in Magento
3. Test connection again

Symptoms: File uploads but Merchant Center shows no update.

Check:

1. Filename matches? Merchant Center expects specific filename
2. Feed format valid? Check for XML errors
3. Feed registered? Ensure data source is configured in Merchant Center

Test connection outside Magento:

# Using sftp command
sftp -P 19321 username@sftp.googleproductfeed.com

# Using lftp
lftp -u username -p 19321 sftp://sftp.googleproductfeed.com

After first successful upload:

1. Go to Products → Data sources
2. Click Add data source
3. Select SFTP
4. Enter the filename your extension uses
5. Set processing schedule (or leave as "Process as soon as possible")

Check feed health regularly:

1. Products → Diagnostics - View errors and warnings
2. Products → Data sources - See last processing time
3. Products → All products - Verify product count

SFTP credentials are stored encrypted in Magento's configuration. Access is limited to admin users with configuration permissions.

If your server has strict outbound rules, allow:

• Host: sftp.googleproductfeed.com
• Port: 19321
• Protocol: SFTP (SSH-based)

Periodically rotate SFTP passwords:

1. Generate new credentials in Merchant Center
2. Update in Magento configuration
3. Test upload works with new credentials
