What is changing

The medication request and immunization endpoint data can now be filtered by the last updated parameter.  

Additionally, a new attribute, Meta.lastupdated, is now available for these resources.

Why we’re making the change

We’re making this change to enable API users to pull different data in lieu of the all-time data set resulting in an increase in API call performance and a decrease in load on our infrastructure.

What will current users of the endpoint need to update in their code

Current users who want to filter the resource output based on the last updated date can now add a _lastUpdated parameter in the URL using the following URL convention: 

a-<practice_id>.E-<enterprise_id>&intent=<order or plan>&_lastUpdated={gt|lt|ge|le}[date]

For example: 

/MedicationRequest?patient=a-11287.E-3605&intent=order,plan&&_lastUpdated=lt2015

What will happen if users of the endpoint do not update their code

This is an additive change. Nothing will happen if changes are not made.
