Supplier API security: protecting your data during integration
Every integration involves credentials: keys to your suppliers' APIs and keys to your own store. In the wrong hands, a store key can change prices, read customer data or delete products. A supplier key can expose your purchase prices or exhaust your request limits. A few habits keep these risks small.
Give each integration the minimum access it needs
Most store platforms let you create API keys with specific permissions. A tool that updates prices and stock needs write access to products, not access to customers, orders or payments. Create a separate key for each integration with only those rights.
Keep credentials out of shared places
- Do not send API keys in chat messages or e-mail threads with many recipients.
- Do not keep them in shared spreadsheets or documents.
- Store them in the integration tool itself or in a password manager.
Rotate and revoke
- Replace keys periodically and immediately after an employee or contractor who had access leaves.
- Revoke keys for integrations you no longer use.
- Keep a short list of which keys exist, who created them and what they are for.
Use secure connections only
Supplier APIs and file links should use HTTPS. If a supplier still offers plain HTTP or unencrypted FTP, ask whether a secure option is available, especially when the data includes prices and terms you do not want exposed.
Validate what comes in
Security is also about integrity. A compromised or broken supplier feed can push wrong data into your store. Basic checks help: no zero prices, no unusually large price changes without review, no sudden drop in the number of products.
Watch for unusual activity
Check your store's API logs from time to time. Requests at unexpected times or from unknown integrations are worth investigating.
Share less data
When you send data to partners, such as dropshipping clients or marketplaces, include only what they need. Purchase prices and supplier names usually stay internal.
