Check if User Account Exists

Fetching Nav user account information is done through GraphQL query. See Using our GraphQL API and account GraphQL Query.

Used to determine if a Nav user account exists and get basic account information.

Required arguments:

• userID

User ID

The userID argument is a unique identifier created by you to link your user to our data. It is a required argument for almost all our queries and mutations. It can be any string, up to 255 characters long.

Example

import fetch from 'node-fetch'

const doesAccountExist = async (userID) => {
  // Use GraphQL to request an Authentication Code
  const response = await fetch('https://api.nav.com/partners/graphql', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'x-api-key': 'my-secret-api-key',
      'x-partner-id': 'my-partner-id',
    },
    body: JSON.stringify({
      query: `
        query CheckAccountExists($userID: String!) {
          account(userID: $userID) {
            userID
          }
        }
      `,
      variables: {
        userID: userID
      }
    })
  })
  const responseData = await response.json()

  return !!responseData.data.account
