Canada Post API create label error - "Contract Number is a required field.\r\n"

[rodriguezljr]

I'm trying to create a label with the carrier Canada Post via API, but after i enter all the relevant fields for the api call the system returns a 500 error response:

 "Message": "An error has occurred.",

    "ExceptionMessage": "Contract Number is a required field.\r\n",

    "ExceptionType": "SS.Business.Shipping.Exceptions.ShippingProviderException"

This is a weird error because it is not in shipstation docs and i'm not sure what to pass as a parameter even though i have the contract number.

Has anybody had this same issue before?

Just wanted to say that yes, I have had this issue persistently the only workaround was to get OneBalance but now that we have a credit account I would greatly prefer to use the standard Canada Post. Has anyone solved this?

Hi @anxvtg, 

Thanks for being a part of our community and for your comment. I see that you were able to reach out to our support team about this and get some answers. 

 Just for community knowledge, this error can occur because of a mismatch of account types. If anyone else is seeing this error message I would first recommend reaching out to our support team, as there are some troubleshooting steps we can assist with when attempting to remove and re-add the account.
