Developer Features in 21R1

We are pleased to bring you the following additions and enhancements to Developer Portal features in 21R1. REST API features added in 21R1 only affect API v21.1, unless otherwise noted.

For issues fixed in a release, see the "Developer Features" category of the fixed issues list in Vault CDMS Help.


Enhancements to API Limits

Release Date: 20R3.4 - February 5, 2021

As of 21R1, the Vault API no longer enforces daily limits and no longer returns the daily limit HTTP Headers in responses for calls made using v21.1 and higher. The daily limit also no longer appears in Admin > Settings > General Settings and will not be returned in the API Usage log. Previous versions of the API will return static values for the daily limit headers:

Additionally, the burst limit has been raised to 2,000 calls in a five-minute fixed period. When the burst limit is exceeded, Vault delays all API calls for 500ms and no longer returns an error. Users who exceed the burst limit are logged in the System Audit log and can also be viewed in the API Usage log. Users no longer receive notifications when burst limits are exceeded.

Retrieve Code Requests

Release Date: 20R3.4 - February 5, 2021

Users may leverage the API to retrieve Code Requests. Studies that use a third-party system for clinical coding may use the Retrieve Code Requests API to extract the Code Requests generated by Vault EDC data and retrieve any updates out of Vault CDMS. This API may retrieve no more than 1000 records per request. It uses the lastmodifieddate parameter as a bookmark to paginate records.
