New Fields

Two new optional fields have been added to the sendTrip request payload.

​
1. namesignURL string · optional

A URL pointing to a pre-generated namesign asset for passenger pickup. Supported file types: HTML, PDF, or an image. Best practice for URL structure (not required, but recommended): 
# Extension-based
https://example.com/booking/123456789/namesign.pdf
https://example.com/booking/123456789/namesign.png
https://example.com/booking/123456789/namesign.html

# Parameter-based
https://example.com/booking/123456789/namesign?format=PDF
https://example.com/booking/123456789/namesign?format=PNG
Usage guidance:
Include namesignURL in the payload so the receiving operator can display the namesign to their driver.
If the inbound payload contains a namesignURL, your system should render it. On mobile devices, display it full-screen for easy passenger identification at pickup.

​
2. tripAttributes array · optional

An array of structured attribute objects describing special requirements or services for the trip. The code field is required on each item; all other fields are optional. Schema:

Backward Compatibility

Both fields are optional. Existing integrations require no changes. If your platform does not send these fields, trip processing is unaffected.
