To resolve this "Unauthorized Error", reach out to your DPD account representative to verify:

  1. You are using the correct credentials.

  2. Your credentials are enabled for EasyPost API usage (contact your DPD Rep)

  3. If you're connecting a "DPD Local" account, ensure you've connected to EasyPost using "Interlink Express" in EasyPost's carrier account page.

    You can not use the DPD UK integration for DPD Local (formerly known as Interlink Express). If you are not sure what kind of DPD account you have, contact your DPD account representative.

If the error persists after you've made sure the credentials are accurate, and have connected your account using the correct carrier on EasyPost, request assistance from EasyPost by contacting them at [email protected].
