patch https://api.finmo.net/v1/fx-conversion/simulate
This API works only in sandbox and allows you to simulate completion of a FX Conversion.
To complete the fx-conversion, it must in PENDING status. Upon successful execution of this API, the fx-conversion status will change to COMPLETED or CANCELLED.
You will get a 406 error if the fx-conversion is not in PENDING status or if you try to complete an already completed or cancelled fx-conversion.
Finmo does not support cancellation of FX conversion at the moment. Our platform works based on a good funds model and will always check the balance in source currency before it progresses further, secondly for cancellation to work it would be based on spot rates and the FX rates would be different and could result in a loss to you.
