Improved
Planned API behavior correction on Custom Experience

custom_experience_id: nullexplicitly creates the Signature Request without a Custom Experience. - If your integration currently relies on the absence of
custom_experience_idto create an unbranded Signature Request, explicitly set the field tonullafter September 8th, 2026.
