Provide the following information in your request:

  1. The user email for the account tied to the Developer Portal.
  2. The required API model: https://developerportal.thomsonreuters.com/gosystem
  3. Request to enable any required subscriptions.
  4. Request that they set up the app in your Developer Portal and confirm when it's complete.
