Getting Started
Base URLs
The base URLs for the VA Facilities API in the various environments are:
Sandbox: https://sandbox-api.va.gov/services/va_facilities/v0
Production: https://api.va.gov/services/va_facilities/v0
Authorization
API requests are authorized through a symmetric API token, provided in an HTTP header with name apikey.
Response Formats
Clients may request several response formats by setting the Accept header.
application/json - The default JSON response format complies with JSON API. This media type is not available for bulk requests using the /facilities/all endpoint. It will return 406 Not Acceptable.
application/geo+json - GeoJSON-compliant format, representing each facility as a feature with a point geometry.
application/vnd.geo+json - Deprecated. Prefer application/geo+json.
text/csv - Available for the bulk download operation only. Some structured fields are omitted from the CSV response.
Response Elements
Some data elements within the response are only present for facilities of a given type:
The patient satisfaction scores contained in the satisfaction element are only applicable
to VA health facilities.
The patient wait time values contained in the wait_times element are only applicable to
VA health facilities.
The list of available services in the services element is only applicable to VA health and
benefits facilities.
The operational hours special instructions contained in the operationalhoursspecial_instructions element is only applicable to VA health and Vet Center facilities.
Facility ID Formats and Constraints
A facility ID has the format prefix_stationNumber. The prefix is one of nca, vc, vba, or vha. Cemeteries may be national (VA) or non-national; non-national cemeteries have the station number prefixed with an s. There are no other constraints on the format. Examples:
Health: vha_402GA
Benefits: vba_539GB
National cemetery: nca_063
Non-national cemetery: nca_s1082
Vet center: vc_0872MVC
Mobile Facilities
The mobile health facilities move regularly within a region. If a facility comes back from this API with "mobile": "true", the latitude/longitude and address could be inaccurate. To get the exact current location, please call the number listed.
Deprecations
activestatus field is deprecated and replaced with operatingstatus.
application/vnd.geo+json media type is deprecated and replaced by application/geo+json
