Identity Resolution APIs

The Identity Resolution (IDR) API includes two ways to match your request criteria to entities in the Dun & Bradstreet database.

• Identity Resolution returns multiple results based on the request parameters.
• Cleanse and Standardize returns the standardized version of the input parameters.
• Match and Append returns the best match plus the requested data product response.

For more information on the Identity Resolution feature please see the Identity Resolution guide.

If you have a large number of entities to submit (more than 4000), D&B Direct+ also provides a Multi-Process API for this purpose. For additional information, please see:

Before using any API, you must have an access token; see the Authentication page for more information.

The following resources are available:

• Error and Information Messages is a list of all error messages with explanation and suggested actions.
• JSON sample containing all possible response elements.
• Open API (Swagger) specification which can aid in development for consuming the responses.
• Postman collection allowing you to run the APIs from Postman.
