Internal GCAPI
Calling GCAPI
A basic call to GCAPI looks like this:
http://[como-URL]/api/[api-subsystem].php?passcode=[my-passcode]&op=[operation]&encoding=[json|xml]
The como URL and passcode are from the results of a GCManage API remote login call. The como URL is what GCManage determines is the path to the como system. This can either be proxied or the direct IP of the system. passcode is the authentication mechanism used by GCAPI -- it is a code generated every 24 hours by a system and reported to GCManage. subsystem names the subsystem you want to work on and operation defines the actual operation to perform. Each operation can have a number of other parameters that will be passed via other parameters in the URL.
Local Application Authentication
Applications may also want to call the API without an associated GCManage account. GrandCare will provide each application an "application key" that allows for a simple way to fetch the required passcodes. To do this, call the API via "localhost" using the following URL:
http://[como-URL]/api/system.php?op=getpasscodes&appkey=[gc-provided-app-key]
This will return the required passcodes for making authenticated calls to the API. See the section on the System API Subsystem for more information about the getpasscodes API call.
Results From GCAPI
The response from GCAPI will either be encoded in JSON or XML, depending on the requested encoding. By default the response will be encoded in XML.
XML Results
By default, GCAPI responds to commands by returning an XML document. Here is the most basic success result:
<gcapi> <result>SUCCESS</result> </gcapi>
The root XML element for all GCAPI results is gcapi. The other always present element is result, which contains either SUCCESS or FAILURE, depending on whether the call succeeded or not. A failure response also contains the fail-message element, which gives the reasons for the failure. For example:
<gcapi> <result>FAILURE</result> <fail-message>Invalid credentials for API call</fail-message> </gcapi>
This result would occur if invalid credentials were supplied during the GCAPI call.
JSON Results
GCAPI can also respond by returning a JSON object. Here is the most basic success result:
{
"gcapi": {
"result": "SUCCESS"
}
}
A failure encoded in JSON looks like:
{
"gcapi": {
"result": "FAILURE",
"fail-message": "Invalid credentials for API call"
}
}
API Subsystems
History
The History subsystem allows you to fetch ADL and wellness data from a system. All of the operations take the same parameters and return different data.
bp
Fetches blood pressure sensor history from the system

- offset - [optional] - Skip this number of entries. Useful for paging
- date - [optional] - Returns only entries for this date
- days - [optional] - Returns entries for the last number of days
- devices - [optional] - Comma separated list of devices to get data. Can be a single device
- resident - [optional] - ID of resident to limit data to
Results
SUCCESS, the total number of readings, and a list readings.
