Signing request by SHA-256 HMAC

Hello all,

I try to get data from an REST API of the marketplace real.
Each request must be signed by a SHA-256 HMAC in base64 encoding.

The description is here: real.de Onlineshop API Documentation

I dont get the solution, does someone has an example how I can handle the authorization by using the same UNIX-Timestamp from a header?

Thanks in advance for your help.

Postman has a built-in JavaScript library that can calculate HMAC. See here an example.

What exactly have you tried and where did you get stuck?
