Key field filters

When requesting data you can optionally pass additional parameters that will filter the data returned by a key field.

Parameter	Description	Examples
General	Parameters described in overview	user=user&password=user&version=3.3
Company	The company context	company=1
Record ID	ID of a specific record to use as a filter	client=1/F667
Response	Returned data	A JSON string containing the data

In this example a list of activities is returned but is filtered to only return activities for a specific client

http://<SERVER>/jsonapi/activities.json?company=1&version=3.3&user=user&password=user&style=modeldata&modelstructure=activitylist&client=1/F667

To poll for created/modified records..

http://<SERVER>/jsonapi/activities.json?company=1&version=3.3&user=user&password=user&style=modeldata&modelstructure=activitylist&timestampoffsetfrom=-900

http://<SERVER>/jsonapi/activities.json?company=1&version=3.3&user=user&password=user&style=modeldata&modelstructure=activitylist&timestampoffsetfrom=-900

The list of key fields that can be used as filters include:
