A contact resource contains information about a user who is known, perhaps through an email exchange, to another user. Contacts are just like entries in an address book. The person who is listed as a contact does not have to give his or her approval. For example, Joe can add everyone from his school to his address book, and he does not need to ask each of them for permission to be added to his list of contacts.


Use this URI to get a single resource for the user specified by {guid}. The {cid} is the ID. You can get IDs by running an HTTP GET operation to retrieve a collection of contacts. Then, you can extract the value of the {cid} field from each Contact Object in the collection. With the {cid} field, you can then run an HTTP GET operation to retrieve a single contact or run an HTTP DELETE operation to delete a single contact.

The Contacts section provides the details for obtaining the Contact Object.

This is the syntax for getting or deleting a specific contact with the {cid} for a specific GUID.{guid}/contact/{cid}

JSON Syntax for Contact Object

Example Responses for GET Contact

In the following responses, you can see the URIs which identify the exact location of each information block. You can use the URI to access specific fields for this contact. See the Single Field section for details.
