Use the Update Account Owner for Multiple Accounts endpoint to assign multiple accounts to a different user in your team's Apollo account.
To update more than the account owner, such as domains or phone numbers, use the Update an Account endpoint instead.
This endpoint requires a master API key. If you attempt to call the endpoint without a master key, you will receive a 403 response. Refer to Create API Keys to learn how to create a master API key.
