Migration Path

• Retirement API

  • No breaking changes were made to the retirement API (/quotes and /orders endpoints).

• Web migration

  • For entities that created a profile on Carbonmark, you could get information about them by using the GET /users/:walletOrHandle endpoint. In this new version of the API you should use the GET /teams endpoints.

    • Example: https://v16.api.carbonmark.com/teams?wallet_address=0xf3de051d4183b1a9a1258c9815cedb0ac725a65f
• Other breaking changes

  • If you were using the GET /holdings endpoint make sure that you take into account that the amount attribute is now a number.

  • If you were using the retireeProfile information from the Retirement model; you would need to perform an additional query to the GET /teams endpoint (see Web migration).

  • If you were using the batches and batchesPrices attributes of the Listing model, please contact us.
