Automatically downloading price lists from suppliers is a critical element of online store inventory management. Manually processing files from dozens of suppliers takes hours of work and creates the risk of information becoming outdated. Modern systems allow you to set up automatic price list imports from various sources: email, FTP/SFTP servers, direct HTTP links, and cloud storage.
In this guide, we'll cover all the main methods for automatically uploading price lists, their settings, advantages, and security recommendations. Proper automation will save you up to 15-20 hours a week on routine operations and ensure your catalog is always up-to-date.
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
Filtering emails
Set up processing rules for automatic price list recognition:
- Sender: email addresses of specific suppliers
- Email subject: keywords "price list", "catalog"
- File extensions:.xls,.xlsx,.csv,.xml,.zip
- Attachment size: spam protection limit
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
FTP vs. SFTP: Security Issues
SFTP (SSH File Transfer Protocol) - a modern standard that necessarily uses encryption:
- All data is transmitted in encrypted form.
- Protection against interception of logins and passwords
- GDPR and PCI DSS compliance
- Ability to use SSH keys instead of passwords
Recommendation: Always use SFTP instead of regular FTP when working with sensitive data.
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
Setting up HTTP import
Main parameters:
- URL: full file address or API endpoint
- Method: GET (usually) or POST for APIs
- Authentication: Basic Auth, Bearer Token, API Key
- Headers: additional headers (User-Agent, Accept)
- Timeout: response time (30-60 seconds)
- SSL verification: certificate verification for HTTPS
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
Advantages of cloud storage
- Convenience: a familiar interface for suppliers
- Automatic synchronization: files are always up to date
- Version history: the ability to roll back to a previous version
- Sharing: easy to manage rights
- Mobility: access from any device
- Reliability: backup and high availability
Setting up automatic downloads
To work with cloud storage you will need:
- Access a file or folder from a provider
- Set up an API connection (for automation)
- Specify the path to the file in the cloud
- Set a schedule for checking for updates
- 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
Recommended intervals
- High frequency products (electronics, currency-dependent): every 2-4 hours
- Average frequency (clothing, shoes, accessories): 1-2 times a day
- Stable assortment (furniture, building materials): once a day or every other day
- Rare changes (books, stationery): 2-3 times a week
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
Problem notifications
Set up alerts for critical situations:
- Email or SMS if key price lists fail to load
- Notification about a long absence of updates
- Price Change Warning (Possible Error)
- Alert when there is a significant change in the quantity of goods
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
Backup
Ensure secure storage of critical data:
- Daily backup of the price list database
- Archiving source files from suppliers
- Storing backups in a separate physical location
- Regularly check for recovery possibilities
- Documenting the disaster recovery procedure
