Documentation Review

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


Maergo is a Live Rating integration, enabling real-time rate retrieval for shipments created via EasyPost.

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

Billing is directly handled by Maergo. EasyPost does not participate in the billing process for Maergo services. Contact a Maergo representative for details.
