No, you can't move your account to another company. If you're going to join another company you'll need to create a StubHub developer account and use a different email address. You can also close your account, but you won't be able to use this email address to sign in to a developer account.
A company is a collection of team members working within your organization. As an administrator on our standard, premium or enterprise plan, you can invite people to join your company, and then track each team member's usage, manage roles and more.
Each of our APIs falls under a product line: Event Catalog, Inventory Management, Order Management, Sales Management, or Market Intel. You can review our APIs to learn more about what they offer. After you create your StubHub developer account and subscribe to our APIs, you can play around with the APIs to see how they work and figure out what you need.
