Between 11–12 March 2026, some users of the API Demo environment experienced difficulties signing in and accessing certain test endpoints. This occurred during routine improvements to the demo gateway.
Affected users saw messages such as invalid credentials or 429 rate‑limit responses. This only affected testing activity in the demo environment for a limited period.
The situation arose when the Demo environment briefly began using a newer gateway that expected a different token format. Since many users were still using the previous format, this created compatibility issues that led to the authentication and rate‑limit behaviour observed. Returning the environment to the earlier gateway immediately restored all expected functionality.
