Multi Field Request

With Resolve, the ability to match on one or many input fields is available. Resolve to individuals by sending any identifiers you may already have, such as an email address(es), Twitter handle, LinkedIn URL, phone number(s), name and location(address), name, social URLs, MAIDs, and more.

The more contact data inputs you can provide either via API or Batch, the more accurate and precise we can get with our identity resolution capabilities. If your Multi Field Request contains incomplete identifier combinations alongside valid inputs, the valid inputs only will be used to identify and resolve an individual. For example, if a name/address combination does not adhere to what is acceptable alongside a valid email, only the valid email will be used to lookup an individual.

When providing inputs, there’s a few helpful tips to keep in mind:

When providing inputs, there’s a few helpful tips to keep in mind:

• To use MD5 emails, be sure to first lowercase and ensure any extraneous characters (e.g. extra spaces or surrounding quotation marks) are stripped off.
• To use postal address, a name is required alongside the input and vice versa.
• Only one name/address combination can be included in the API request
• To use an international phone number, a country code is required.
• There is a maximum of 25 identifiers by type that you may use in your multi field request. A 400 Response will be returned if there are more than 25 identifiers for any given identifier type.

Location or Name in request

Authorization

Authenticating with the FullContact API is accomplished through the use of an API key.
You can generate and manage your API keys from the FullContact Platform UI

When accessing the FullContact API, include your API Key within the "Authorization" header of your POST,
using a prefix of "Bearer". An example of this is shown below.

curl -X POST https://api.fullcontact.com/v3/identity.resolve \
 -H 'Authorization: Bearer {Your API Key}'

❗️

Keep Your API Keys Secret

Your API keys are essentially like passwords to access the FullContact API, and should be kept secret. Do
not embed them in client-side code or post them in publicly accessible areas such as support forums or GitHub.
It is a common and easy mistake to accidentally copy and paste code snippets, including your API key,
when seeking help - be sure to remove your API key and any other sensitive information before posting.
