*IMPORTANT NOTICE: All applicants please read immediately applicant System-to-System provides applicants (with a high volume of application submissions) a web services interface for automated submission of completed grant applications and related services. The system allows applicants who submit grant applications frequently, to save time and resources by eliminating the need to reenter repetitious data into multiple individual application forms and therefore streamlines the application submission process. The system is designed for secure e-business transaction processing and provides a platform independent messaging service that follows the Simple Object Access Protocol (SOAP) with attachments specification.

NOTICE: Applicant System-to-System Endpoint Access Limitation

The system is currently experiencing strain due to frequent user access. Applicant System-to-System users are asked to limit their entry into the system for querying opportunities and checking application submission status to NO MORE THAN ONCE PER HOUR to reduce the load on the LDAP server.

Testing of any sort (i.e. application package submission) within the live Production environment is strictly prohibited. All S2S privileges will be revoked for any certificate associated with a test application package in the Production environment. All testing for must be completed in AT07.

Note: The Applicant System-to-System 2006 Endpoint has been terminated. Applicant System-to-System users are to access the system using the 2007 Applicant System-to-System Endpoint:

Applicant System-to-System Interface provides:

  • Platform Independent Messaging Service
  • Security (Secure Socket Layer (SSL) and mutual authentication)
  • Opportunity Schemas and Instructions
  • Automated Grant Application Submission
  • Validation (XML vs. Schema Check)
  • Applicant Status Tracking

*Please Note: does NOT provide certificates necessary to communicate with the system, software to populate the grant application XML, agency specific validation or web services to directly communicate with backend agencies.

NOTICE: Special Characters not Supported will only accept ASCII characters in XML, while other characters may be supported by the schema, they may cause differences in the resulting hash value generated when the application is processed by resulting in a FATAL error in the submission.
