Update a Contact
Contacts API

URL Parameters

contact_id

The ID of the contact to be retrieved, as returned by GET. It typically follows the format c-###-####, but is not guaranteed to do so, and should be treated as an opaque string.

Query Parameters

city

company

The contact's company, church, or other organization. It will be printed beneath the name and above the street address.

country

Leave the country blank if the contact is in the United States.

For non-US addresses, use the English name of the country (e.g. Germany rather than Deutschland). Place other elements of the address in the city, state, and postal_code fields normally.

For example, even though German addresses place the postal code before the city name, keep the city in the city field and the postal code in the postal_code field. Our software automatically reformats international addresses as needed when printing envelopes.

external_id

Use this field to store your application's identifier for this contact.

file_as

The name we should use when showing this contact in a list. It is usually in the format LastName, FirstName for individuals, or just the regular name for companies and churches.

If the file_as parameter is cleared, a new one will be generated automatically, based on the contact's name (using the updated name, if applicable).

greeting

The name we should use in the first line of a mail-merged letter, usually following the word "Dear".

If the greeting parameter is cleared, a new one will be generated automatically, based on the contact's name (using the updated name, if applicable).

name

The contact's full name, as it should appear on the first line of an envelope.

postal_code

state

street

The street address may contain multiple lines
