e-RS FHIR CHANGE NOTIFICATION - Strict enforcement of FHIR instant datatype

It has been identified that the e-RS APIs are not strictly enforcing fields using the FHIR instant datatype.

The FHIR documentation defines the FHIR instant datatype as follows:

“An instant in time - known at least to the second and always includes a time zone.”

The e-RS currently incorrectly accepts FHIR instant values that:

  1. Do not have a time component (i.e. date only)
  2. Have a date and time but are missing the timezone

In January 2025 the e-RS will start rejecting FHIR instants that do not have a time component (1).

Later in the year the e-RS will start rejecting FHIR instants that do not contain a timezone (2).

Please take action now to ensure your integration is not impacted by these changes.

We have already contacted partners that have provided non-compliant values in the Integration or Production environment in the last 3 months.
