Hello stawan,

Welcome to the DigiKey TechForum! Although there are many resources available on the TechForum, the DigiKey API requires a different pathway for troubleshooting. The FAQ portion of the API does outline some issues, however I believe in your specific case you will need to reach out to our developer team directly by using the link below.
