Sandbox is down

hantranjp — Sun, 12 Jul 2026 20:22:47 GMT

Hello,

Currently, the https://apitest.cybersource.com/microform/v2/sessions is timing out on my local machine and on the Cybersource docs: https://developer.cybersource.com/api-reference-assets/index.html#flex-microform

Anyone else?

The iframe for inputs is also down: https://testflex.cybersource.com/microform/bundle/v2.12.1/iframe.html

Since both the microform v2 sessions endpoint and the Microform iframe were timing out, that seems to point more toward a sandbox-side issue than a problem with the local integration.

For anyone still seeing this kind of behavior, it would be useful to compare the same request from another network and check whether the iframe URL fails independently of the capture-context request. If both fail from different environments, that is a pretty strong indication that the issue is upstream rather than related to the merchant configuration.
