Shared Services: Using Web Services With Other Grant Systems

If you have spent a year or more in the federal grants world – whether as an applicant or as a federal employee – you may have noted the wide range of federal grant systems that are used across the government.

It is lesser known among grant pros that has created a range of web services – often called application programming interfaces (or APIs) outside the grant world – that system administrators can use to link their grant systems to

Web Services for Applicants also has web service integrations that can be used by applicant-focused systems.

Maybe an organization has a high volume of submissions, thus making a proprietary system that integrates with more financially feasible.

Or perhaps an organization desires to use a single system for human resources and financial management. In such a case, federal grant submissions could be processed from within the entity’s system thanks to a web service.
