fdsh-client

A Node.js client for the Federal Data Services Hub (FDSH)

Install

Install with npm:

npm install fdsh-client

Synopsis

Setup a bunch of config data:

const fdsh = require('fdsh-client');
const fs = require('fs');
 
// connectivity config
const host = 'dev.hub.cms.gov'
const port = 5443
const path = null
const userId = 'MY_USER_ID'
const password = 'MY_PASSWORD'
const cert = fs.readFileSync('/path/to/cert.pem')
const key = fs.readFileSync('/path/to/key.pem')
const connectivityArgs = { host, port, path, userId, password, cert, key }
 
// method-specific config
const firstName = 'MARK'
const middleName = ''
const lastName = 'WHITE'
const ssn = '277025100'
const dob = '1991-07-08'
const methodArgs = { firstName, middleName, lastName, ssn, dob }
 
// some simple callbacks
let onThen = result => console.log(result)
let onCatch = err => console.error(err)

Then you can start feeding it to methods that correspond to FDSH services.

For example, the Hub Connectivity Service:

fdsh.HubConnectivityService.hubConnectivityCheck(connectivityArgs)
  .then(onThen)
  .catch(onCatch)

…outputs:

{ ResponseMetadata: { ResponseCode: 'HS000000', ResponseDescriptionText: 'Success' } }

The Verify SSA Composite Service:

fdsh.VerifySSACompositeService.verifySsa(connectivityArgs, methodArgs)
  .then(onThen)
  .catch(onCatch)

…outputs:

 
{ SSACompositeIndividualResponse:
  { ResponseMetadata: { ResponseCode: 'HS000000', ResponseDescriptionText: 'Success' },
    PersonSSNIdentification: '277025100',
    SSAResponse:
    { SSNVerificationIndicator: 'true',
      DeathConfirmationCode: 'Unconfirmed',
      PersonUSCitizenIndicator: 'true',
      PersonIncarcerationInformationIndicator: 'false',
      SSATitleIIMonthlyIncomeInformationIndicator: 'true',
      SSATitleIIAnnualIncomeInformationIndicator: 'false',
      SSATitleIIMonthlyIncome: [Object] } } }
