Create and update clients

Create a client

You can use the buyers.clients.create method to create a Client that represents one of your clients.

Here are some things you can do with a Client resource:

  • Reference the client in negotiations with publishers.
  • Subscribe the client to auction packages.
  • Manage the client's access to the Authorized Buyers Marketplace UI.

The following sample demonstrates how you can create a new Client with the create method.

Patch a client

You can use the buyers.clients.patch method to update an existing Client. For example, you can use patch to update the displayName. The following sample demonstrates how you can update a Client with the patch method.
