API for Data Sharing and Reporting

Largest consideration is if an API that returns immediate results is best solution or a callback mechanism.

Need to consider paging, exclusions for data, fields, documents
- 50/100 registrations at a time suggested, possible a single Registration as well?

Need to work with usage - can the client use their paging logic

Need to open the API Gateway, get API keys to clients

Invocation mechanism needs to be known - how often will the API be used? How often do refreshes happen?

Effort depends on fields to be included
