Multi-Field Request is a feature enhancement to our Enrich API launched on July 1st, 2019. It adds the ability to match multiple input fields that may be available instead of just one. Using multi-field requests, you can submit any contact identifiers you already have for a given individual:

1. Personal/work email address (hashed or clear text)
   
2. Phone number(s)
   
3. Mobile Ad IDs
   
4. Social ID
   
5. Social URL
   
6. Social username 
   
7. Record IDs
   
8. PersonIDs
9. Name and home address (must have both and not available on the trial plan)
   

These identifiers will be used to resolve to an individual and return additional information through Insights Bundles enabled for your account. 

Why Multi-Field?

• Noticeable increase in Match Rates
  

• Ability to query based on new & combination identifiers like name & address
  

• More secure authorization
  

Who has access to Multi-Field Request?

All users of Enrich API will have access to Multi-Field Enrich. However, users of our v2 API will not have access to the multi-field request. We recommend that you upgrade to Enrich API to access this powerful capability.  

How to use Multi-Field Request?

Multi-field request capability will be available on the existing Enrich API endpoint and there is no need to generate a new key. However, you will need to change the way input is passed to the API. 

So, what’s changed for the input fields?

1. You will now be able to search on one or many email addresses and phone numbers for a given contact.
   

2. Email Hash is now part of the email input field instead of its own input field.
   

3. You will now be able to search on social IDs, URLs, and usernames (except Facebook and Instagram).
   

4. You can now search on location or name in the request, if both are present and follow the laid combination it enhances call out.
