KEX-Angebote-API

⚠️ You'll find German domain-specific terms in the documentation, for translations and further explanations please refer to our glossary

General

These APIs allow the calculation of Schaufensterkonditionen as well as calculating and accepting Angebote based on a Vorgang. All APIs documented here are GraphQL-APIs.

This API may contain advanced beta features that are still in development. Beta features may undergo modifications or be removed at a later release.

⚠️ This API is continuously developed. Therefore we expect all users to align with the "Tolerant Reader Pattern", which requires clients to be tolerant towards compatible API changes when reading and processing the data. This means:

  1. unknown properties must not result in errors

  2. Strings with a restricted set of values (Enums) must support new unknown values

  3. sensible usage of HTTP status codes, even if they are not explicitly documented

Authentication

These APIs are secured by the OAuth 2.0 client credentials flow using the Authorization-API. To use these APIs your OAuth2-Client needs the following scopes:

Scope Label in Partnermanagement Description
privatkredit:angebot:ermitteln KreditSmart-Angebote ermitteln Scope for calculating Schaufensterkonditionen and Angebote
privatkredit:antrag:schreiben KreditSmart-Anträge anlegen/verändern Scope for accepting an Angebot (creating an Antrag)

Request

These APIs accept data with the content-type application/json with UTF-8 encoding. The fields inside a block can be sent in any order.

The APIs support all common GraphQL formats. More information can be found at https://graphql.org/learn/queries/.

The body of a GraphQL request contains the field query, which includes the GraphQL query as a String. Parameters can be set directly in the query or defined as variables. The variables can be sent in the variables field of the body as a key-value map. All our examples use variables.

{
  "query": "...",
  "variables": { ... }
}

Error codes

One of the special features in GraphQL is that most errors are not reflected via HTTP error codes. In many cases you receive a status code 200, even though an error has occurred. These GraphQL errors can be found in the errors field of the response body. More information about error codes can be found here.

HTTP-Status Errors

Error Code Message Description
401 Unauthorized Authentication failed
403 Forbidden The API client misses a scope
415 Unsupported MediaType The wrong content type was used

GraphQL Errors

Error Code Message Description
400 Bad Request Request format is invalid (mandatory fields are missing, wrong parameter names or values, ...)
403 Forbidden The authenticated user does not have sufficient rights
409 Conflict The Vorgang was updated after the offer was calculated and before the offer was accepted

Schaufensterkonditionen

Schaufensterkonditionen, both the top Schaufensterkondition and a complete list, can be retrieved via our GraphQL API using HTTP POST.

The URL for the Schaufensterkonditionen is:

https://kex-angebote.ratenkredit.api.europace.de/schaufenster

Query Top-Schaufensterkondition

Hints

  • The calculation of Top-Schaufensterkondition requires a valid auszahlungsbetrag and laufzeitInMonaten. If the provided values are not valid, an GraphQL-Error with the status code 400 is returned.

Request

The GraphQL-Query is called topSchaufensterkondition and contains the following parameter:

Parameter Name Type Default Value Details
partnerId Partner-ID The Partner-ID of the API Client
auszahlungsbetrag Euro! - (mandatory field) Value must be greater than 0
laufzeitInMonaten Int - (mandatory field) Value must be greater than 0
finanzierungszweck Finanzierungszweck Calculation over all values of Finanzierungszweck
datenkontext Datenkontext TESTUMGEBUNG

Response

The Query returns a Schaufensterkondition.

Angebote

You can calculate a list of machbare and vollständige Angebote using data of a Vorgang via our GraphQL-API using HTTP POST. Using the id of the corresponding Angebot you can accept it.

The URL for calculating and accepting Angebote is:

https://kex-angebote.ratenkredit.api.europace.de/angebote  

Query Angebote

Hints

  • The calculation of Angebote is only possible if the corresponding Vorgang includes a valid Kreditbetrag and Laufzeit or Rate. Should that not be the case the API user receives a GraphQL-Error with the status code 400. The Vorgang has to be corrected before you can continue.
  • Please provide the correct value for the vertriebskanal. That is important in order to deliver e.g. the correct documents for B2B and B2B2C and to generate appropriate and valuable reporting.
  • To empower API users with insightful predictions and enhance API capabilities, a feasibility prediction score was added. Based on a prediction model, this score is a beta feature that aims at predicting the likelihood for a Vorgang to secure reliable machbare Angebote. The score is in percent. The higher the score value, the more likely the Vorgang will lead to machbare Angebote. In case of an error while calculating the feasibility score, the Angebot will be returned with an empty score field.

Request

The GraphQL-Query is called angebote and has the following parameters. If only the vorgangsnummer is provided, only complete offers will be returned.

Parameter Name Type Default Value
vorgangsnummer String! - (mandatory field)
options AngebotOptions { includeVollstaendigkeitsstatus: [VOLLSTAENDIG], includeMachbarkeitsstatus: [MACHBAR], vertriebskanal: B2B2C }

Response

The Query returns a list of Angebote.

Example

POST Request
POST https://kex-angebote.ratenkredit.api.europace.de/angebote
Authorization: Bearer xxxx
Content-Type: application/json

{
  "query": "query angebote($vorgangsnummer: String!) {
    angebote(vorgangsnummer: $vorgangsnummer) {
      ratenkredit {
        produktanbieter {
          name
        }
      }
      gesamtkonditionen {
        sollzins
        effektivzins
        gesamtkreditbetrag
      }
    }
  }",
  "variables": {
    "vorgangsnummer": "ABC123"
  }
}
POST Response
{
    "data": {
        "angebote": [
            {
                "gesamtkonditionen": {
                    "effektivzins": 2.99,
                    "gesamtbetrag": 10916.88,
                    "sollzins": 2.95
                },
                "ratenkredit": {
                    "produktanbieter": {
                        "name": "Testbank AG"
                    }
                }
            }
        ]
    }
}

Mutation Angebot-Annehmen

Hints

  • Currently the API only supports Fernabsatzgeschäft.
  • The vertriebskanal that was used to query the offers will be used when an offer is accepted, if no vertriebskanal was provided the default value B2B2C is used. That is important in order to deliver e.g. the correct documents for B2B and B2B2C and to generate appropriate and valuable reporting.
  • When accepting an offer the authenticated user needs to have a Handelsbeziehung for the corresponding bank, which allows the acceptance. Otherwise the user receives a GraphQL-Error with the status code 403.
  • Accepting an offer is only possible if the Vorgang did not change in the meantime. Should there be updates between the calculation of offers and accepting an offer the user receives a GraphQL-Error with the status code 409. In this case the calculation of the offers needs to be done again.
  • To optimize the process we might calculate alternative offers.
  • The Kundenbetreuer of a Vorgang is important for accepting an offer as the name and contact details will be sent to the bank.

Request

The GraphQL-Mutation is called angebotAnnehmenand has the following parameter:

Parameter Name Type Default Value Comment
vorgangsnummer String! - (mandatory field)
angebotId String! - (mandatory field) The ID of the calculated offer that is to be accepted

Response

This Mutation returns a jobId.

Example

{
  "data": {
    "angebotAnnehmen": {
      "jobId": "AB12345678"
    }
  },
  "errors": []
}

Query Annahme-Job

Hints

  • If the offer cannot be accepted from the bank, the response will contain status=SUCCESS but not contain any Antrag.
  • A partner can only query jobs that were created by this partner otherwise a 403 FORBIDDEN is returned.
  • Only complete offers can be accepted, if an incomplete offer is requested, it will result in a 400 BAD REQUEST

Request

The GraphQL-Query is called annahmeJob and has the following parameter:

Parameter Name Type Default Value Comment
jobId String! - (mandatory field) The ID of the job, which was returned when initiating the acceptance process
jobOptions JobOptions { includeMachbarkeitsstatus: [MACHBAR]

Response

This Query returns an AnnahmeJob. It contains the Status of the acceptance process and the Antrag if the process was successful.

POST Request
POST https://kex-angebote.ratenkredit.api.europace.de/angebote
