Title: API Connection StatusAPI Authorization failure Last modified: January 30, 2024 --- # API Connection StatusAPI Authorization failure * Resolved [tarzine](https://wordpress.org/support/users/tarzine/) * (@tarzine) * [2 years, 4 months ago](https://wordpress.org/support/topic/api-connection-statusapi-authorization-failure/) * I have contacted USPS to request for access, and received a service request number. * I am getting the following message after I added the password “**API Authorization failure. User [ my user name] is not authorized to use API RateV4.**“ * I mostly ship 6×8 kraft envelope and most of everything I ship is under 2 ounces. We want open our store up internationally and we need rates to do that. I would like to get this resolved as soon as possible, so I can start shipping.

To obtain > these permissions, contact [webtools@usps.gov](https://wordpress.org/support/topic/api-connection-statusapi-authorization-failure/webtools@usps.gov?output_format=md). * Our plugin uses the following APIs: - RatesV4 - IntlRateV2 * These should be included in the response along with the details of the account for which you are requesting the access. * If you encounter any difficulties, please let us know we will be happy to help.

I even contacted USPS through the given email address. They said that the permissions were granted, but I’m still getting the same error.

Has the status of the API connection been updated? * Best regards, Tomek * [reddrikc](https://wordpress.org/support/users/reddrikc/) * (@reddrikc) * [2 years, 4 months ago](https://wordpress.org/support/topic/api-connection-statusapi-authorization-failure/#post-17391421) * Hey [@tograczyk](https://wordpress.org/support/users/tograczyk/), I communicated with USPS again and it seems like the problem has been resolved.

They sent me the same message a second time as a response. Frustrated is an understatement, why did they make this so much more complicated than it used to be. I never had issues historically doing this. * ![Image](https://i0.wp.com/media.discordapp.net/attachments/375850495367053342/ 1202683452793823312/image.png?ssl=1) * Plugin Support [Tomek Graczyk](https://wordpress.org/support/users/tograczyk/) * (@tograczyk) * [2 years, 4 months ago](https://wordpress.org/support/topic/api-connection-statusapi-authorization-failure/#post-17392004) * [@tarzine](https://wordpress.org/support/users/tarzine/) Thank you for the confirmation. * Did you add the USPS shipping method to your WooCommerce shipping zones after getting the API connection? * [https://octolize.com/docs/article/usps-adding-the-usps-live-rates-shipping-method/](https://octolize.com/docs/article/usps-adding-the-usps-live-rates-shipping-method/)– How to add the USPS Live Rates shipping method? * Could you please send a screenshot of your shipping zones and USPS plugin settings? * — * [@jcapehart2](https://wordpress.org/support/users/jcapehart2/) There have indeed been changes in the way you can access the API.
