The SKY API will eventually provide access to the most valuable and commonly used data objects in Raiser's Edge NXT and Financial Edge NXT.
Until full release of all objects, the API will be limited in scope, with the Raiser's Edge NXT being restricted primarily to Constituent details first, and Financial Edge NXT restricted to General Ledger initially.
Specific timing and order of subsequent objects, fields, functions, etc. is subject to change, and will be determined by partner and client feedback.
