Mydema API for developers

Connect your e-shop or ERP to Mydema directly: live shipping prices at checkout, shipments and vouchers for paid orders, tracking and the prepaid credit wallet.

Integration guide

Authentication, request and error conventions, every endpoint with examples, and the rules an integration must follow.

Getting started

  1. Log in to the Mydema panel and add your store under Settings › Integrations with the Add Site button.
  2. Copy the API key it generates. It starts with mk_live_ and is shown once.
  3. Load credit: shipping vouchers are paid from your prepaid Mydema credit.
  4. In Postman import the collection and one environment, select the environment and paste your key into the apiKey variable.
  5. Run the requests in order, starting with Plugin login. The token, basket id and chosen route carry over from one request to the next.
