Buró de Crédito credentials

"claveUsuario" and "contrasenaUsuario" are the username and password provided by Buró de Crédito. They must be valid and your Buró de Crédito account active in order to query in production.

If you want to use "vault", is possible to manage variables instead of use credentials in hard code.
For example, instead of use the next code:

  "encabezado": {
    "claveUsuario" : "USER123456",
    "contrasenaUsuario" : "PASS1234"

You should use the next:

  "encabezado": {
    "claveUsuario" : "@vault:secretVaultName:1",
    "contrasenaUsuario" : "@vault:secretVaultName:2",
    "nombreUsuarioCompleto": "@vault:secretVaultName:3"

Where secretVaultName is the name of the credential created in vault.
:1 means that link take the first tuple value of the vault credential with the name "secretVaultName".
:2 means that link take the second tuple value of the vault credential with the name "secretVaultName"
:3 means that link take the "User Consulting to Buró de Crédito" value of the vault credential with the name "secretVaultName"
