This service retrieves the signature data associated with the signature Ids specified in the URL.
You can specify up to 5 Id values at a time.
No request body is used for this service.
|updated_since||ISO 8601 timestamp||Finds items by modification time. This retrieves only those objects with one or more timestamp members, one of which falls after the specified timestamp.|
|list_all||false (default), true||(only usable with updated_since) If set to true, list_all retrieves a comprehensive list: ProductName returns a larger set of results that includes the IDs (or primary key values) of every object that falls within the selection range and the JSON for the updated objects. Setting list_all to true can be used, for example, if you need to refresh a local cache.|
On success, the response body contains a JSON array of signature objects:
|id||string||Uniquely identifies the signature data. When set, it indicates that an event has been signed by a driver.|
|data||string||Contains the binary signature data encoded as Base64. The specification for encoding binary signature data is as follows:
Signature data begins with a header section, followed by a number of point collections. To reconstruct the signature, each of these point collections must be rendered in turn with connecting line segments.
