Thanks for your help.
I solved the problem, i will post a guide for anyone that has the same problem.
1- You need to create an user to get the token, the user must be for OAuth2.
[Follow the Clients Credentials Grant Steps]
2- You need to found your endpoint of your API, i see that this depend of your proyect’s version, in my case is https://[My-Domain]/api/oauth/access_token
3- The HTTP Request Method need to be POST.
4- In body Parameters you will introduce the grant_type (client_credentials in this case), the client_id and the client_secret
5- When you executed your Node, if all run correctly, you will get your token access.
