I have a question regarding REST API

[정석인]

Hello, I'm a user who wants to implement an automated trading program using the Upbit Open API. https://docs.upbit.com/docs/create-authorization-request

Labview is using the 2015 version.

When executed separately, the upper sequence receives an error response, and the lower sequence receives a normal response.

I'm not sure what went wrong in the sequence above.

Where should I fix it?

If you let me know the information you need, I'll answer it
