Links included in the message are also converted to hyperlinks in the email. The message may contain the following html tags including a, abbr, acronym, b, blockquote, code, em, i, ul, li, ol, and strong. Be aware that when the text to html ratio is too high, the email may end up in spam filters. Custom styles on these tags are not allowed. If this field is not passed, a default message will be used.

Name of the signature request.

The destination folder to place final, signed document and signing log. Only ID and type fields are required. The root folder, folder ID 0, cannot be used and can also not be null.

When this value is not passed in when the signature request, then we will use a default folder which is either the parent folder of the first source file in the payload if we have the permission to upload to that folder or a folder called "My Sign Requests".

object arrayin bodyrequired

Array of signers for the signature request. 35 is the max number of signers permitted.

Note: It may happen that some signers belong to conflicting segments (user groups). This means that due to the security policies, users are assigned to segments to prevent exchanges or communication that could lead to ethical conflicts. In such a case, an attempt to send the sign request will result in an error.

Read more about segments and ethical walls.

It is an entity that belongs to a Sign Request and can only be used/accessed within this Sign Request. A signer group is expected to have more than one signer. If the provided value is only used for one signer, this value will be ignored and request will be handled as it was intended for an individual signer. The value provided can be any string and only used to determine which signers belongs to same group. A successful response will provide a generated UUID value instead for signers in the same signer group.
