Payer Finder API

  • Finds payer ID values that meet certain criteria
  • Is a “helper/utility” API that other MN APIs use (tradingPartnerServiceId in Eligibility request, and so on, which is the Payer ID. This is required to request benefit information from an insurance carrier. This will vary based on the payer you want to connect to.) Here is a list of test tradingPartnerServiceId
  • Returns results of a search to JSON structure
  • Exports filtered (or unfiltered) results to CSV file
