For Partners that want to sign up for their first account for testing the Sandbox or Production, a new account can be created by including a signupKey in the URL path. This associates your Partner configuration and rate sets directly to your account. Also, you should use this method if you intend to have your own master account, where you control the payment wallet and pay for shipping costs directly to Packagehub.
Sandbox: https://portal-qa.packagehub.com/signup?SignupKey={signupKey}
Production: https://portal.packagehub.com/signup?SignupKey={signupKey}
If you are an Integrator Partner that wishes to allow individual customers to sign up for their own PackageHub account to manage their payment wallet and pay shipping costs directly to PackageHub, please reference the Partner Signup Link and Email Invite to Landing Page.
