Saxo Bank Updates OpenAPI Requirements for Brokers

Saxo Bank has announced significant updates under its OpenAPI requirements that will directly affect introducing brokers. The changes, designed to enhance the bank’s risk model, will require brokers to adapt their systems ahead of the enforcement date. Saxo confirmed that the adjustments are already live and strongly advises partners to begin implementing them immediately to avoid disruptions.

The update impacts several endpoints. Specifically, the POST cm/v1/signups endpoint will now include the new NatureOfBusinessWithCategory property. Meanwhile, Saxo Bank will remove the GET cm/v1/signups/options endpoint and continue the GET cm/v2/signups/options endpoint with enhanced mapping logic.

These modifications represent a step toward tighter compliance and greater transparency in client onboarding. As part of the new framework, the Nature of Business (NOB) will be extended with additional values, and every NOB value will now fall under a specific category. This dual requirement means that both the NOB value and its associated category must be presented to the end user during the signup process. 

Saxo highlighted that this change is crucial to aligning client profiles with its strengthened risk assessment standards. Furthermore, the bank confirmed that enforcement will begin on December 1, 2025. By this date, Saxo Bank will completely remove the older cm/v1/options endpoint that lacks the updated parent property mapping logic. Consequently, introducing brokers must transition fully to the new system before the deadline. Saxo noted that the early release of the updated mapping logic and properties gives firms ample time to prepare, test, and integrate the adjustments into their workflows. 

In addition, the institution emphasized that adopting the changes early will help partners avoid operational challenges and ensure smooth onboarding experiences for clients. While the technical requirements may demand system reconfiguration, the improvements are expected to deliver long-term benefits in terms of compliance, security, and risk management. With this announcement, Saxo reinforces its commitment to building a more robust and transparent trading environment. Introducing brokers using Saxo’s OpenAPI must now act swiftly and align their systems well before the December 2025 enforcement date.
