EnvelopeCustomFields Resource
The EnvelopeCustomFields resource provides methods that allow you manage custom fields in an envelope.
Custom fields can be used in the envelopes for your account to record information about the envelope, help search for envelopes and track information. The envelope custom fields are shown in the Envelope Settings section when a user is creating an envelope in the Docusign member console. The envelope custom fields are not seen by the envelope recipients.
There are two types of envelope custom fields:
