How to automatically download price lists from email, FTP, or a link?

Downloading price lists from email

Email remains one of the most common methods for receiving price lists from suppliers. Many companies send updated files via email on a daily or weekly basis.

Setting up automatic import from email

Basic connection parameters:

• Protocol: IMAP or POP3 (IMAP is preferred for storing emails)
• Server: imap.gmail.com, outlook.office365.com, or your ISP's server
• Port: 993 for IMAP SSL, 995 for POP3 SSL
• Authentication: login/password or OAuth2 for Google/Microsoft

Benefits of Email Import

• Does not require technical knowledge from the supplier
• The supplier controls the frequency of shipments.
• The history of all updates is saved in your mailbox.
• It's easy to add a new supplier - just email

Safety recommendations

Use a dedicated email address only for receiving price lists. This simplifies filtering and improves security. Enable two-factor authentication and use app passwords instead of your primary email password.

Downloading from FTP/SFTP servers

FTP (File Transfer Protocol) and its secure version, SFTP, are the professional standard for exchanging files between companies. Large suppliers prefer this method for regularly updating their price lists.

Setting up an FTP connection

Connection parameters to the provider's server:

• Host: ftp.supplier.com or the server's IP address
• Port: 21 for FTP, 22 for SFTP
• Login and password: provided by the supplier
• File path: /prices/current.xlsx or /export/price_list.csv
• Mode: Passive (PASV) for working through NAT/Firewall

Automatic file downloads

Set up an FTP server check schedule:

• Daily: for suppliers with frequent price changes
• Weekly: for stable price lists
• According to the schedule: on certain days of the week (for example, Monday and Thursday)
• On file change: check modification date, download only when updating

Working with multiple files

Some suppliers host multiple files on FTP for different product categories. Use file masks for automatic processing:

• price_*.xlsx - all files starting with "price_"
• *_2025-10-*.csv - current month files
• Processing by folders: /new/, /archive/

Download via HTTP/HTTPS link

Downloading a price list via a direct link is the simplest and fastest integration method. The supplier hosts the current file on the web server, and your system downloads it periodically.

Types of HTTP links

1. Direct link to the file

The simplest option is a direct link to the file:

• https://supplier.com/exports/price_list.xlsx
• https://partner.com/feeds/current_prices.csv
• https://api.provider.com/files/catalog.xml

2. Dynamic URLs with parameters

Links with parameters for filtering or authentication:

• https://supplier.com/export?key=YOUR_API_KEY&format=xlsx
• https://partner.com/price?client_id=12345&date=today
• https://api.provider.com/v1/prices?category=electronics

3. API endpoints

REST API for retrieving structured data in JSON or XML:

• Requires an API key or authorization token
• Return data in a standardized format
• Supports pagination for large catalogs
• May provide additional metadata

Benefits of HTTP Download

• Simplicity: does not require setting up an email or FTP client
• Speed: direct download without intermediate steps
• Reliability: works via the standard HTTP/HTTPS protocol
• Monitoring: It's easy to check link availability
• Caching: Using HTTP headers for optimization

Working with protected links

For security, many providers use authentication:

• Basic Authentication: login and password in the request header
• API Key: unique key in URL parameters or headers
• OAuth 2.0: access token for API integrations
• IP Whitelist: access only from permitted IP addresses

Cloud storage (Dropbox, Google Drive)

Cloud file storage services are becoming a popular way to share pricing, especially for small and medium-sized businesses.

Google Drive

Integration methods:

• Public link: the provider makes the file available via a link
• Shared folder: access to a folder with regularly updated files
• Google Drive API: programmatic access via OAuth2
• Service Account: automatic access without user intervention

Dropbox

Connection options:

• Shared Links: direct links to files for downloading
• Dropbox API: integration via API keys
• Shared folders: file synchronization between accounts
• Webhooks: file change notifications

OneDrive / SharePoint

Microsoft cloud solutions for corporate clients:

• Integration with Office 365 / Microsoft 365
• Microsoft Graph API for file access
• Azure AD support for authentication
• Versioning and file change history

Setting up automatic downloads

To work with cloud storage you will need:

1. Access a file or folder from a provider
2. Set up an API connection (for automation)
3. Specify the path to the file in the cloud
4. Set a schedule for checking for updates
5. Configure processing of new file versions

Automating the download process

After setting up data sources, it is important to properly organize the automatic process of updating price lists.

Update schedule

Factors in frequency selection:

• Price volatility: How often do supplier prices change?
• Competition: the criticality of relevance to your niche
• System load: data volume and processing time
• Supplier's working hours: when he updates prices

Processing order

When working with multiple suppliers, it is important to organize the queue correctly:

• Prioritization: key suppliers first
• Parallel processing: several price lists at the same time
• Night loading: main process during non-working hours
• Division by categories: grouping similar price lists

Error handling

Typical problems and solutions:

• File unavailable: try again in 15-30 minutes
• Invalid format: administrator notification, file skipping
• Partial data: decision to apply or reject
• Authentication error: credentials verification, notification
• Timeout: increase waiting time or optimization

Logging and monitoring

Keep detailed logs of all operations:

• Download start and end time
• Uploaded file size and number of records
• Operation success or error code
• Changes in data (new products, price changes)
• Processing time and resources used

Versioning and backups

Save the history of downloaded files:

• Archiving source files: storage 30-90 days
• Database snapshots: before applying changes
• Price change history: to analyze the dynamics
• Rollback option: restore previous version

Safety and compliance

Automatic price list downloads involve the transfer of confidential commercial information. Reliable data protection is essential.

GDPR Compliance

When working with European suppliers, please consider GDPR requirements:

• Data encryption: during transmission (TLS/SSL) and storage
• Data minimization: upload only the necessary information
• Access rights: restricting access to credentials
• Logging: audit of all data transactions
• Data Processing Agreement: agreement with suppliers

Secure storage of credentials

Recommendations:

• Do not store passwords in clear text in configuration files.
• Use an encrypted vault for credentials
• Use different accounts for different providers
• Change your passwords regularly (every 3-6 months)
• Use strong, unique passwords

Malware protection

Files from external sources may contain threats:

• Antivirus scan: scanning all downloaded files
• Isolated processing: sandbox for file parsing
• Format validation: checking for compliance with the expected type
• File size: maximum size limit
• Extension whitelist: only allowed file types

Network security

• Firewall: limiting outgoing connections
• IP Whitelist: connect only to known servers
• VPN: secure channel for critical data
• SSL/TLS: mandatory encryption for all protocols
• Certificate Pinning: checking server certificates

Conclusion

Automatic price list uploading isn't just a time saver; it's a fundamental element of a modern online store's competitiveness. A properly configured system allows you to:

• Save 15-20 hours a week on manual file processing
• Improve data accuracy by eliminating the human factor
• Ensure prices are up-to-date in real time
• Scaling your business without proportional growth of staff
• Improve relationships with suppliers through secure data exchange

Selecting a download method

Email import Suitable for small stores with 5-10 suppliers, does not require technical skills from contractors.
