The Trade Desk API - Troubleshooting

Updated on Jul 8, 2026

While configuring your The Trade Desk API connection, you may encounter several issues. Understanding these common errors can help streamline the setup process and facilitate quick resolutions.

Authorization failed on connect (personal login instead of API credentials)

Error message:

Error
"This user does not have access to the API."

This message appears in Improvado when you try to connect The Trade Desk. It happens when the credentials entered are your personal The Trade Desk website login, which cannot be used for an API connection. The Trade Desk API requires dedicated Platform API credentials.

Solution:

  • Request dedicated Platform API credentials from your The Trade Desk Account Manager. The API login is usually prefixed with ttd_api_ (for example, ttd_api_username@domain.com) and is different from your normal TTD website login. See Get Started with the TTD API.
  • Make sure Public API access is enabled for that API user (your Account Manager enables this on the account side).
  • Reconnect the integration in Improvado using the ttd_api_ login and password.

Authorization issues

Error message:

Error
"Access Denied. You do not have the required permissions to perform the requested action."

This error occurs when the authenticated user does not have Public API access enabled in The Trade Desk Partner Portal. Even if your login and password are correct, the API token will not have the necessary permissions without this enablement. or when the API access token has expired. Since TTD uses a login/password authentication flow that issues a short-lived token (valid for 24 hours),

Solution:

  • Ensure you’re using the refreshed token in your API calls (tokens expire every 24 hours).‍
  • ‍Ask your Trade Desk representative or account manager to enable Public API access for the user you authenticate with — at minimum the PublicAPI_General_View scope, plus any additional scopes your integration requires. This is an account-side setting and one of the most common blockers when connecting to the TTD API.

Wrong permissions

Error message:

Error
"The user does not have all permissions needed to generate the report."

‍‍This error occurs when the user can view reports but does not have permission to create or schedule them.

Solution:

  • Ask your Account Manager to grant Scheduling API access and report creation permissions.
  • In User Management Platform (UMP), ensure the API user:
    • Has access to the required advertisers
    • Has permissions to create and schedule reports (not view-only)

An admin can review and update these settings in UMP.
