Documentation Review

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


Jitsu is a Live Rating integration, enabling real-time rate retrieval for shipments created via EasyPost. Rates are guaranteed valid for a minimum of 5 minutes.

  • When creating a shipment, EasyPost requests Jitsu for shipment rates specific to the user's Jitsu account.
  • The rates provided are directly from Jitsu and tailored to the user's specific account details.
  • In cases of discrepancies or incorrect rates, users are advised to contact their Jitsu account representative.
  • The representative can then update the rates in Jitsu's database to ensure user account accuracy.
