PARTNER_AUTHENTICATION_FAILED

@chetan singh - Thank you for your question. The PARTNER_AUTHENTICATION_FAILED error indicates an issue authenticating your integration.

There are a few possible causes of this error and you should likely see another exception message that is more meaningful. For example, The specified Integrator Key was not found or is disabled. An Integrator key was not specified. or The specified Integrator Key was not found or is disabled. Invalid account specified for user.

The first error usually indicates that the “Authorization: Bearer {accessToken}” header in your API call is missing or not formatted correctly. The second error usually indicates that you are calling the wrong base path in your request URL. For example maybe you are trying to make a call to your production account, but are using the demo environment’s base URL in your request URL.

Here is a very helpful blog post that provides more detail on this error:
