Signature Request

Create Embedded Signature Request

Creates a new SignatureRequest with the submitted documents to be signed in an embedded iFrame. If form_fields_per_document is not specified, a signature page will be affixed where all signers will be required to add their signature, signifying their agreement to all contained documents. Note that embedded signature requests can only be signed in embedded iFrames whereas normal signature requests can only be signed on Dropbox Sign.

Client id of the app you're using to create this embedded signature request. Used for security purposes.

hide_text_tagsboolean

Enables automatic Text Tag removal when set to true.

NOTE: Removing text tags this way can cause unwanted clipping. We recommend leaving this setting on false and instead hiding your text tags using white text or a similar approach. See the Text Tags Walkthrough for more information.

The custom message in the email that will be sent to the signers.

metadataobject

Key-value data that should be attached to the signature request. This metadata is included in all API responses and events involving the signature request. For example, use the metadata field to store a signer's order number for look up when receiving events for the signature request.

Each request can include up to 10 metadata keys (or 50 nested metadata keys), with key names up to 40 characters long and values up to 1000 characters long.

subjectstring

The subject in the email that will be sent to the signers.

test_modeboolean

Whether this is a test, the signature request will not be legally binding if set to true. Defaults to false.

use_text_tagsboolean

Send with a value of true if you wish to enable Text Tags parsing in your document. Defaults to disabled, or false.

Controls whether auto fill fields can automatically populate a signer's information during signing.

NOTE: Keep your signer's information safe by ensuring that the signer on your signature request is the intended party before using this feature.
