Private Constituent Lookup

The Constituent Lookup API is a RESTful API.

This service provides external Compassion clients the ability to retrieve constituent information based on the constituent's email address.

The service returns JSON as default. The service will also return XML. This is controlled by the Accept parameter in the Message Header (i.e., for XML, it should be "Accept: application/xml" and for JSON, it should be "Accept: application/json").
