The Purolator tracking API only allows you to track packages with your own API keys. This means if you’ve added your Purolator account to the EasyPost API, and you try to generate a tracker without enabling tracking services, the tracker will not create any status updates within EasyPost.
In order to generate valid Purolator trackers within EasyPost, you must first have Purolator enable your accounts API keys for tracking services. Purolator can enable your API key to work with EasyPost tracking services by reaching out to them at this link: https://www.purolator.com/en/support/contact-us
