Hi @Gio for your integration to work you need only the “Private Key”, not the “Identifier” or the “Public Key”. when saving the new private key, you need to copy the whole content like below

-----BEGIN RSA PRIVATE KEY-----
MI…………..w==
-----END RSA PRIVATE KEY----- 

I could see that you have two private keys. You need to make sure your code reference the updated one.
If the new saved private key is different from the generated one, you would need to reach out to Azure or the developer of this integration.

Con esgta informacion, donde tengo que ir para obtener el

Y el clientId, cual es es este:IdUsuario = 'xxxxxxx-5443-42c6-9e31-xxxxxxxxxxxxx'

Donde generamos el impersonatedUserId… es lo que nos falta… 

The impersonatedUserId is the one you want to authenticate as. This could be your own UserID or the UserID of any user from your Docusign account. The UserID can be found by going to Admin > Users > open the user you want to impersonate. The UserID is the GUID shown below User ID
