About Producto Requerido and your Buró de Crédito users

You need to check with Buró de Crédito the privileges associated to your users before starting to query. Some products need specific privileges. We strongly recommend to review it with your Buró de Crédito contact.

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": {
    "productoRequerido": "501",
    "tipoResponsabilidad": "I",
    "tipoContrato": "AF",
    "claveUsuario": "KK25251001",
    "contrasenaUsuario": "kiban123"

You should use the next:

  "encabezado": {
    "productoRequerido": "501",
    "tipoResponsabilidad": "I",
    "tipoContrato": "AF",
    "claveUsuario": "@vault:secretVaultName:1",
    "contrasenaUsuario": "@vault:secretVaultName:2",

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"

For more information about vault, please visit our knowledge center in this link or visit the API related to vault in this link.

Also there you can see our options to update automatically the password of your "Buró de Crédito" user. Soon we will have an API to check the validity of your username and password manually.

If you don't want to use vault, to test the call in our sandbox environment we recommend using this credentials:
claveUsuario: KK25251001

The "autenticacion" segment within the query is only meant to be sent if you're using this process to receive your customer's authorization to check his credit report.

Data cleaning

Before sending the data to Buró de Crédito, kiban cloud performs data cleaning, necessary to prevent Buró de Crédito from sending back an error.

Here are the validations and transformations we are performing:

  • Validate that the data you included is alphabetical.
  • Remove the accents.
  • Replace the letter Ñ by N.
  • Remove the special characters.
  • Put letters in uppercase.
  • Remove spaces at the beginning and end of values (trimming).
  • Allow compound surnames, for example, Del Toro.
  • Do not allow two names in the primerNombre field.
  • Remove commas from the address field.
  • Split the address if it is greater than 40 characters : we then send the address in two different fields (40 caracteres max per field) to Buró de Crédito.

If you detect transformation in the data that you included in your call, this is because of the rules mentioned above, required to make a successful call to Buró de Crédito.
