# Troubleshooting Applications

Troubleshoot and resolve problems with your Creators API–enabled websites or applications.

* **Register for Amazon Associates before registering for the Creators API**.

  After you have your Store ID (Partner Tag) from [Sign up as an Amazon Associate](en-us/onboarding/sign-up-as-an-amazon-associate), use the primary email address in your Associates account to [register for the Creators API](en-us/onboarding/register-for-creators-api.md). Use `partnerTag` in all requests to Creators API calls.

* **Check that you are specifying inclusive resources**

  You may not receive the expected information in your Creators API response if you have specified resource(s) that does not return the data you want.

* **Check the structure of your request**.

  Each Creators API operation has a reference page. Verify that your request uses the parameters correctly. For more information, refer [Operations](en-us/api-reference/operations.md).

* **Try your request with multiple ASINs or Keyword search strings**.

  The Amazon catalog is large and sometimes individual products have irregular data results.

* **Check how quickly your application is submitting requests**.

  If your application is submitting requests faster than allocated throughput (transactions per second), you may receive `ThrottleException` errors from the Creators API until you decrease the rate of your requests. For more information, refer [API rates](en-us/concepts/api-rates.md).
