There are two versions of the Sendcloud API: API v2 and API v3. API v3 is our latest version and is receiving active updates, with new features and improvements over API v2. API v2 is our legacy API and is entering maintenance mode. It is still available for existing users but will not receive new features. For new users, we recommend starting with API v3 to make use of the latest features and improvements. If you need help with moving to API v3, check out our migration guide.

​
What does maintenance mode mean for API v2?

API v2 is starting to enter maintenance mode as of April 2026, which means:
  • Endpoints that enter maintenance mode are closed to new users. New users should use API v3 instead.
    • There is an exception for Sendcloud Partners, who may still use API v2 for new accounts. If you are a Sendcloud Partner, ensure you pass the Sendcloud-Partner-Id header to your requests.
  • Existing integrations remain fully functional. If you are using API v2 and your Sendcloud account was created before April 2026, you can continue to use it without interruption. It is still possible to rotate your API keys and create new API integrations for users who created their Sendcloud account before April 2026.

Endpoints in maintenance mode

Currently, only the Create a parcel or parcels endpoint in the Parcels API v2 is in maintenance mode and therefore closed to new users. Other v2 APIs are still available for new users, but we recommend using API v3 for all new integrations to benefit from the latest features and improvements.
