Hi @davidsonsns , Looking at our API request and response logs and there seems to be quite a bit of requests within a short time span to create a funding source, initiate micro-deposits, and verify micro-deposits. I’m wondering if there is some contention in the Sandbox with the volume of requests that is causing issues with the state of the resource. I passed this on to our engineering team for further investigation.
@davidsonsns , we believe this is due to the sequence of requests where the Funding Source is being removed which removes micro-deposits. When we receive the request to verify, which is causing the 404, the funding source had already been removed.
