The SimpleSell API is a REST API that lets you connect your own systems to SimpleSell. Use it to create parcels from your shop, ERP, or warehouse software. SimpleSell then processes them into shipping labels and customs declarations. With the API, you can:
  • Create, update, and delete parcels
  • Process parcels to generate shipping labels and tracking numbers
  • Print parcels and download labels and customs declarations as PDF
  • Cancel parcels
  • List and filter parcels, for example to get the tracking numbers of processed parcels
  • Look up your shipping methods and packagings

​
Requirements

To use the API, you need a SimpleSell account on the Essential plan or higher. You can also use the API during your trial. The Free plan doesn’t include API access. Requests from accounts without API access return 402 Payment Required.
