signature_invalid: Failed to validate signature

Started by Matt K -   in API Authentication

Hello,

My name is Oleg, I am a developer of a partner app. I have been seeing the error with message 'signature_invalid: Failed to validate signature' from several clients since 18 May. It raises while invoice and items saving. I have not found any difference in the environment for those clients in contrast to others which are not facing this problem. Also locally in the development environment, all is working fine.

I use ruby 2.3 and own fork of the xero-gateway gem. Any help or direction for further investigation is appreciated. Ready to provide any necessary additional information.
