Examine the EasyPost Objects section to understand the API's structure, which is critical for constructing requests and interpreting responses.

• EasyPost initially returns a one-cent rate for shipments once the CTT Express account is set up.
• CTT Express will charge the appropriate amount for postage via their billing system.

• CTT Express representatives provide rate cards detailing expected costs based on shipment parameters (package size, weight, location, etc.).
• Acquiring this custom rate card from CTT Express is required to receive custom negotiated rates as part of the API rate response.

• Once the rate card is received from CTT Express, users should contact EasyPost support at support@easypost.com for assistance installing this rate card to their account.

Billing is handled directly by CTT Express and follows a bill-on-scan model.

• Charges are applied when the shipment is scanned into the CTT Express network, not at the time of label creation.
• EasyPost is not involved in the billing process.
• All invoices, adjustments, and billing inquiries are managed through CTT Express.

CTT Express Codes are automatically selected per shipment based on the shipment type; however, service levels may also be configured per shipper account.
