Authorization Limits

All Selling Partner API (SP-API) applications are subject to authorization limits determined by the type of selling partner that your application supports.

After your application reaches its authorization limit, you can't add additional authorizations. To maintain flexibility, perform regular audits of your authorizations.

Authorization limit summary

There are two types of authorization: self-authorization (where you authorize your own application) and OAuth authorization (where other selling partners authorize your application). The following table summarizes the available methods and limits by application type.

Application types and limits

This section describes the three types of applications and their authorization limits.

Private applications

Private applications are available only to your organization. The following authorization limits apply:

• Available authorization types: Self-authorization only.
• Authorization limits: Maximum of 10 self-authorizations. To add more authorizations, either update the application to be public or remove existing self-authorizations.

These applications are publicly available to other organizations and are authorized by sellers. The following authorization limits apply:

• Available authorization types: The following OAuth flows: Selling Partner Appstore Authorization Flow or Website Authorization Flow. For testing purposes, you can also self-authorize your public application through the private application authorization workflow.

  • Unlisted applications: Maximum of 25 OAuth authorizations.
  • Self-authorizations: Maximum of 10 self-authorizations for internal testing.
