One key concept within Bisnode Business Contacts is the unique entity ID. This is designed to be a unique, persistent ID for entities within Bisnode, which facilitates for you to be able to get a single customer view across all your databases and systems. This is a necessity to be GDPR-compliant.

Structure your data and find relations

Identify not only companies, but also related offices and decision makers

There are three different entity types in the BBC API: Company, Worksite and Employment. Each entity has its own unique ID. From Company comes the ID for all associated Worksites, and from each Worksite comes the ID for all associated Employments. This means that you can create a structured hiearchy in your company data, and identify relevant relations and decision makers for your business.

How to use the API

This guide is intended to help you get going with your integration against the Bisnode Business Contacts API. It serves as a complement to the  Endpoint Reference  and aims to bring a high level understanding of the key concepts of the platform. 

Schemas are provided for all entity types in this documentation. Most data provided in this API is optional, i.e., a particular field specified in the schema may not appear in the response if no such information is available for that particular entity. An API client should keep this in mind and properly handle missing information.

Entity types and ID:s in BBC API

One key concept within Bisnode Business Contacts is the unique entity ID. This is designed to be a unique, persistent ID for entities within Bisnode.

There are three different entity types in the BBC API: 


The legal, cohesive company, which may have several subordinate worksites


The physical worksite, which may comprise a head office or branch


Decision makers at a particular worksite/office 

Each entity has its own unique ID. From Company comes the ID for all associated Worksites, and from each Worksite comes the ID for all associated Employments. 


Key Features


This method is recommended when direct contact exists with somebody who is able to confirm an identity – such as, for example, via a CRM, app or the web.


Select is used in order to find new customers and to make a selection from a large amount of prospects for a campaign.


This method is recommended for companies whose customer data is unsatisfactory, or when one wishes to supplement a request with Bisnode’s unique ID number in order to exclude certain entities from a prospect selection.


Through Match, Select och Search you can identify the entities that are of interest for you. Via Download you can then get updated and enriched information about these entities.


Keep your data updated and enriched over time by subscribing for changes and new entitites.

Read more about each key feature below, and in the section Endpoint reference.


Search process

1. The client sends a search request to the API containing criteria with significant identification value

2. The API responds with a result that contains basic data in order to confirm the identity

3. A new request is sent, in order to retrieve further information about the selected entity. For output, see the Download section.

Select process

1. Select the entities you wish to be included in your selection by choosing selection criteria

2. In the next step, you get the number of entities within your chosen selection

3. If you are happy with the count, you can go further and retrieve the unique IDs within your selection, which will enable you to exclude any existing IDs

4. Finally, you can download all the selected entities to obtain complete information. For content of the output, see the Download section.

Match process

1. The integrator submits a query to the matching endpoint containing those entities that are to be matched

2. The response contains Matching Type, Status, Customer id and BBC ID (worksite and company ID)

3. If Multiple hits are chosen you can review the hits and choose the ones that are correct

4. Download your matched customers. For content of the output, see the Download section.

Download process

Submit Company, Worksite or Employment ID:s, retrieved from Search, Select or Match. There are three available information packs to download: Company, Worksite and Employment. See Endpoint Reference for content in each pack.

From Company comes the ID:s for all associated Worksites, and from each Worksite comes the ID:s for all associated Employments, so you can combine these information packs and create a structure and hierarchy in your company data. 

Note that there is variation in the coverage of the variables in the information packages and in different countries. 

Countries that are covered in BBC are Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Italy, Latvia, Lithuania, the Netherlands, Norway, Poland, Russia, Slovakia, Spain, Sweden, Switzerland and United Kingdom.

Subscribe process

1. The integrator submits a query to the subscribe endpoint containing BBC IDs from your previous download, that are of interest to monitor

2. If the entity has changed since last modified date, you will get information which fields that have changed, and if there are any deleted or new worksites and/or employments

3. Download your updated customers with complete information


Working with VAT and National Registration Numbers

The BBC API uses its own entity IDs to download and request changes for companies, worksites and employments. This means that to download and request changes for an entity you need to know its entity ID.

To make it easy to work with VAT or national registration numbers, the API provides the possibility of searching by registration numbers and VAT numbers. When downloading a company resource these can be found in the fields nationalRegistrationNumber and vatNo, respectively. You may also search a company or worksite based on these numbers. The outline below illustrates how to convert organization or VAT numbers to BBC IDs.

Use the Search endpoint for companies and filter on nationalRegistrationNumber and companyStatus like so:

1. Search active companies with the desired VAT/registration number, for example: /companies?companyNumber=5564363421&companyStatus=ST00. The companyNumber parameter is used to specify either the VAT or national registration number. The parameter companyStatus=ST00 means that only active companies will be returned.

2. Make sure there is only one hit among the search and extract the ID of that hit. You can now use this ID to download complete company information and use it to query for changes. It is recommended that you save this ID along with the company information to easily query for changed properties.

You can do the same for official worksite numbers if this exists in the country, for example for SE you can search on "cfar".

Changes and versioning

API version is provided in the base of the requested URL in the form of "v1", "v2" etc. Only major version numbers are used.

API versions are raised only on breaking (i.e. backwards incompatible) changes in the API. Fields may be added but will never be removed during an API version lifecycle. When developing your application, take care to ensure that your application is able to handle additional fields.

Get Access

API access

Bisnode provides API access for client developers by means of a CLIENTID and a SECRET. The client developer uses the CLIENTID and SECRET to get an access token from Bisnode's authentication endpoint at https://login.bisnode.com/as/token.oauth2. The access token is then passed along in the Authorization header to all BBC API requests.

Step 1. Get the access token

To get an access token you need to make a POST request to https://login.bisnode.com/as/token.oauth2 using the following HTTP header: Content-Type: application/x-www-form-urlencoded and the following request body: grant_type=client_credentials&scope=bbc. The request must be authenticated using HTTP Basic authentication and a base64-encoded string CLIENTID:SECRET.

Example in cURL

curl -H "Content-Type: application/x-www-form-urlencoded"\

     -X POST -d 'grant_type=client_credentials&scope=bbc'\

     --user base64_encode($CLIENTID:$SECRET)\


Example response


  "access_token": "eyJhb....seAtPCCQ",

  "token_type": "Bearer",

  "expires_in": 7199


Step 2. Use the access token

Supply your access token with all requests to the API using the HTTP Authorization header: Authorization: Bearer <your access token here>. You should reuse the access token for multiple calls to the API. See the next section on recommended usage.

Example in cURL - search for "Bisnode"

curl -H "Authorization: Bearer eyJhb...seAtPCCQ"\


Reusing the access token

After you have fetched an access token you should save it and use it for subsequent calls to the BBC API. There is no limit on the number of calls it can be used for, but it will expire after a certain time.

We recommend that you disregard the value of the expires_in field and that you simply keep using the same access token until it expires, at which point the API will return an HTTP status of 401 Unauthorized. When that happens you should retrieve a new access token from the authentication endpoint and retry the operation. Care should be taken to not introduce an endless loop of failed API requests and getting new access tokens.

The following pseudo code illustrates how to use the authentication endpoint and BBC API.

function make_authorized_bbc_api_request():

    if not has_cached_access_token():





    except bbc_error_status_401_unauthorized:



Backwards compatibility for CRM integrators

To enable use of several users in the same client, use the special header X-BISNODE-USERNAME. This should only be used for backwards comparability for legacy clients. The X-BISNODE-USERNAME enables us to track individual users' usage.




Resources may point to other API resources by means of hyperlinks. The format used for exposing these relations is Hypertext Application Language (HAL).. The content type of all BBC documents is thus "application/hal+json" and clients should treat them as any JSON data but with the extra benefit of having provided links to related resources.


Links promote the idea of explorability and makes it possible to fetch documents right from the web browser (provided an access token is sent along with the request) for casual browsing of the data before connecting through more advanced client applications.

Search navigation

Links are also used for easy navigation of search results for the /worksites and /employments endpoints. By default two links are always available in this context; "first" and "last". If the search result spans more than one page (i.e "hitsReturned" is less than the value of "hitsTotal"), "previous" and "next" links will also be available depending on the current position.
