Although they're often used together, Seller ID and Amazon Merchant Token serve different purposes within Amazon Seller Central and third-party integrations.
🏪 What Is a Seller ID?
A Seller ID is a unique identifier assigned to your Amazon seller account.
Amazon uses it to:
Identify your seller account
Associate listings with your account
Process orders and inventory
Distinguish your business from other sellers
Your Seller ID remains tied to your Amazon seller account and is commonly used in Amazon URLs, reports, and API integrations.
🔑 What Is an Amazon Merchant Token?
A Merchant Token is a unique identifier used when authorizing third-party applications to access your Amazon Seller Central account.
It helps:
Verify account ownership
Connect third-party software (such as AccelerList)
Grant API permissions securely
Authorize data access between Amazon and external applications
Many third-party tools request your Merchant Token during setup or troubleshooting.
📊 Key Differences
Seller ID | Merchant Token |
Identifies your seller account | Used for third-party authorization |
Associated with listings and orders | Associated with API and application access |
Used by Amazon internally | Used during app integrations |

💡 Which One Does AccelerList Use?
AccelerList may use:
Seller ID to identify your Amazon account and retrieve inventory/listing data.
Merchant Token during account setup, authorization, and troubleshooting to verify and connect your Amazon account.
✅ Summary
A Seller ID identifies your Amazon seller account, while a Merchant Token is primarily used to authorize and connect third-party applications like AccelerList to your Amazon account securely.
