Steps to upload your carrier shipping rates

Note: Remember to keep your CSV file under 5 MB or 10,000 rates.


1. Are all fields, except for the postal code, mandatory?
Yes, all fields are mandatory.

2. If the carrier already supports rate API, which rate will have priority?
Currently, if the carrier supports the rate API, you cannot upload your rates. However, if you have such a requirement, feel free to contact us.

3. Will rates be returned in the Label API response if the user has uploaded rates?
Yes, both Rates API and Label API can display the uploaded rates.

4. Can I upload rates that will take effect later?
Yes, ensure you set the real "effective_from" date, formatted as YYYY-MM-DD. Leaving it empty uses the current date. If multiple rates have different effective_from dates, the nearest to today's rate is considered.

5. What happens if I set the overlapped weight range wrongly?
AfterShip doesn't check overlapped weight ranges. Verify your uploaded data for accuracy. Ideally, avoid overlapping weight ranges. If present, the system will consider the earliest rate as the result.
