# Selling Partner Authorizations FAQ
Frequently asked questions about selling partner authorizations.
What is an authorization?
Authorization is the process by which a selling partner grants your Selling Partner API (SP-API) application permission to call the SP-API on the selling partner's behalf. For example, when a selling partner authorizes your order management application, they give your application permission to retrieve their order data through the SP-API. To learn more about authorization, refer to [Authorize Applications](https://developer-docs.amazon/sp-api/docs/authorizing-selling-partner-api-applications).
Is there a limit to how many authorizations my SP-API application can have?
SP-API applications have authorization limits based on the selling partner type your application supports. To learn more about the limits, refer to [Authorization Limits](https://developer-docs.amazon/sp-api/docs/application-authorization-limits).
Why did my selling partner authorization count decrease?
This can happen for several reasons:
1. As part of data-access maintenance, Amazon periodically deactivates application authorizations that have not been renewed by the selling partner in more than 365 days and have not made an API call within this time frame. Selling partners can reactivate at any time through their **Manage Your Apps** page in Seller Central or Vendor Central. To learn more about renewing authorizations, refer to [Reactivate Authorizations](https://developer-docs.amazon/sp-api/docs/reactivate-authorizations).
2. Selling partners can voluntarily revoke authorization of SP-API applications they no longer want connected to their account. To learn more about revoking authorizations, refer to [Revoke Authorizations](https://developer-docs.amazon/sp-api/docs/revoke-authorizations).
Why does Amazon remove selling partner authorizations from my SP-API application?
As part of data-access maintenance, Amazon periodically deactivates SP-API application authorizations that have not been renewed by the selling partner in more than 365 days and have not made an API call within this time frame. This protects selling partner data by ensuring third-party access remains aligned with actual usage. This is a core principle of Amazon's data security practices.
Two principles drive this:
* **Selling partner data protection** - If a selling partner is no longer actively using your SP-API application, their data should not remain accessible. Removing outdated authorizations closes that unnecessary exposure.
* **Least-privilege access** - Permissions should reflect real activity. An authorization with no business need for the selling partner serves no functional purpose. Removing it keeps access scoped to what is in use.
Where can I find steps to test my reauthorization workflow?
When a selling partner reauthorizes your SP-API application, your application needs to correctly exchange parameters with Amazon and receive updated authorization information. If your reauthorization workflow is not set up correctly, selling partners might lose access to your SP-API application when they attempt to reconnect. Test your reauthorization workflow to ensure a seamless experience.
For test scenarios and steps, refer to [Test your reauthorization workflow](https://developer-docs.amazon/sp-api/docs/renew-authorizations#test-your-reauthorization-workflow).
Does removing an inactive authorization disrupt anything for me as the SP-API application developer?
No. Amazon only deactivates authorizations that have not been renewed by the selling partner in over 365 days and have received zero API calls within that time frame. Your SP-API application was not actively using those connections, so nothing in your integration breaks.
What is unaffected:
* Live API calls and active integrations.
* Any authorization where at least one API call was made in the past 365 days.
* Your SP-API application's credentials, client ID, or OAuth configuration.
Does removing an inactive authorization disrupt anything for the selling partner?
No. Amazon only deactivates authorizations that have not been renewed by the selling partner in over 365 days and have received zero API calls within that time frame. Selling partners whose authorizations Amazon deactivated were not actively using your SP-API application. They might see fewer "active" applications within their **Manage Your Apps** page in Seller Central or Vendor Central, but no active workflow is interrupted.
How does a selling partner reactivate a deactivated authorization for my SP-API application?
Selling partners can follow the steps provided in [Reactivate Authorizations](https://developer-docs.amazon/sp-api/docs/reactivate-authorizations).
How does a selling partner reauthorize my SP-API application?
Selling partners can follow the steps provided in [Reauthorize Applications](https://developer-docs.amazon/sp-api/docs/reauthorize-applications).
Does the deactivation of an authorization affect any contracts or agreements I have with my selling partners?
No. Deactivation of an SP-API application authorization is a technical action that removes SP-API data access only. It has no bearing on any service contracts, subscription agreements, or financial arrangements between you and your selling partners. If the selling partner wishes to reactivate, they can follow the steps provided in [Reactivate Authorizations](https://developer-docs.amazon/sp-api/docs/reactivate-authorizations).
