Overview

Spade’s unique approach to transaction enrichment involves matching each transaction to a real merchant entity (”counterparty”) in our database, and returning granular merchant, category, and location information. Matching accuracy is critical, and we have developed a “match score” model that assesses how confident we are that each match is correct. This is a machine learning model that is constantly fine-tuned to create more and more accurate predictions. In addition to using this model to filter out matches that don’t meet a quality bar, we surface results via our API to allow you to make decisions about when and how to use our data.

​
How do I interpret match scores?

Match scores range in value from 0.00 to 100.00 — the higher the match score, the higher the likelihood that a counterparty or location returned was the one involved in a transaction. We return two types of match scores: counterparty match score and location match score. This is not a probability of a match being correct, but simply a representation of our confidence. Over 99% of our matches are accurately scored by the model, despite most confidence scores falling in the 85-95 range. Note, the returned model score is not a probability of a match. While these numbers are not representative of probabilities, they are directionally relevant to the probability of match accuracy. You can be more confident in a 99 score than a 90 score, more confident in a 90 score than an 80 score, and so on.

​
What is the counterparty match score?

  • Counterparty match score is an assessment of how confident we are that a specific counterparty we return is the one involved in a transaction (e.g., how likely it is that WALMART002191BRYANOH is a transaction occurring at Walmart)
  • Counterparty match scores appear in the counterparty portion of the response.

​
What is the location match score?

Note: location match scores are only available on card enrichments.
  • Location match score is an assessment of how confident we are that a specific location we return is the one involved in a transaction (e.g., how likely it is that WALMART002191BRYANOH is a transaction occurring at the Walmart at 1215 S Main Street, Bryan, Ohio).
  • Location match scores are only returned when we match on a location that is identified as physical in the spendingChannel field (it is null for digital transactions)
  • Location match scores appear in the location portion of the enrichment

​
When is a match score not returned?

  • In the rare event we are unable to match a transaction to a counterparty or location in our backing data we will return a null match score.
    • This indicates that the returned data is not based on a match and is instead derived from what was in the request.
    • It can also be identified by the presence of a counterparty or location ID - if no ID is present, no “match” has been made.
  • At times, we may be able to find a counterparty match but not a location match. In these events, the match score in the location portion of the response will be null but the match score in the counterparty portion will be a numerical value.

​
How should match scores be used?

Match scores can help you make decisions about how to use enriched data in your systems. For example, for decision-making processes (e.g. card authorization flows or fraud assessments) we suggest setting a higher threshold on counterparty match score, whereas for customer analysis, budgeting, or UX/UI improvements, a lower counterparty score threshold is sufficient.
