Breaking Changes

We aim to maintain backward compatibility across all of our API releases; however, occasionally we need to make breaking changes. Below you will find a list of future and past breaking changes.

June 28, 2023

We are planning a breaking change to the Paxos v2 REST API List Deposit Addresses service. On June 28, 2023, we are adding a default of 100 results to the limit query parameter and restricting the maximum page limit to 1,000. The 100-results-per-page default applies when no limit, or zero (0), is specified. If the pagination limit is set in excess of 1,000 items, the API returns a Bad Request error, irrespective of the actual number of retrieved items. This change enables Paxos to improve platform stability for all users.

The change is scheduled to be deployed in the Sandbox environment on June 14, 2023, giving you time to prepare and test your integrations. We recommend you test your integrations in Sandbox during the testing window.

Expected Release Date
  • Sandbox: June 14, 2023
  • Production: June 28, 2023
Version Impacted Paxos v2 REST API
Service Impacted Limit Deposit Addresses
Parameter Modified limit
Summary To improve platform stability for all users, all integrations must set a paginated results limit of 1,000 or less.

Please contact if you have any questions or concerns.

  • NOTE: All itBit REST API services will be turned off on April 26, 2023.

Paxos has initiated an End of Life (EOL) process for the itBit REST API (v1). We will discontinue service for all itBit REST Production ( and Sandbox ( APIs on April 26, 2023. After a review of our existing product offerings, we determined that the Paxos REST API (v2) provides a better experience for all users and should be used as the primary entry point for all REST services. See the migration guide for details.

The crypto_network parameter will be required when requesting a crypto withdrawal and when depositing crypto in the Sandbox environment no earlier than February 15, 2023, to facilitate testing. The changes will go live in the Production environment no earlier than February 22, 2023. This change will enable Paxos to support future rollouts of multichain assets and ensure all requests are processed on the intended network.

All integrations must specify crypto_network when using either service by February 22, 2023.
