Common Fields
API objects have a type field indicating their object type. Each object in the API may be given an identifier, indicated via its id field, and will typically be addressable via a URI. Many objects will also have a created_at field indicating the object's creation date as a UTC Unix timestamp.
Dates and Timestamps
All temporal fields in the API are encoded as Unix timestamps and are by definition always treated as UTC. The most common time fields in the API are created_at and updated_at.
| Parameter | Description |
|---|---|
| created_at | The time the object was created. In most, but not all cases, this is the time the object was created according to the API server. |
| updated_at | The time the object was last updated according to the API server. |
Optional Fields
Unpopulated optional data is returned as follows -
- Number, String and Boolean types may be returned as having
nullvalues. - Arrays and Objects may be returned as empty (
[]{})
In general clients should be able to handle null and empty fields.
Metadata and Custom Attributes
Some object types, such as Events, Users and Companies, have a metadata or custom_attributes field that allows clients to set custom-defined data about an object.
