How to detect signature fields in package from PDF

Take a look at this example. You'll find a PDF and a C# class that makes a REST API call to create the package with the appropriate JSON to extract the fields from the PDF. Hope it helps. https://developer.esignlive.com/code-share/document-extraction-rest-api/

Using the same naming conventions for your fields as you'll see in this blog: https://www.esignlive.com/blog/e-signlive-how-to-document-extraction-net-sdk/ You should be able to simply set the "extract:" property in your package JSON payload (package level property) to true and the fields will be extracted. Let me know if you need a full example and I'll gladly get you one. :)

Thank you for the quick response. I've tried following the instructions in that guide before, and I wasn't able to extract the signatures. Following the guide, I've generated PDFs in acrobat with signature fields adhering to the nomenclature specified. After enabling the extract property and making the POST request I still haven't had any luck extracting the signatures yet. If you could provide a full sample with the REST API (preferably with a sample PDF as well), that would be great!

Definitely. I will take a look at this in the morning and get you something, ASAP.

I tried with a JSON that looks something like the below with a field named [Signer1.Capture1] to extract signature field. The create package works but when I try retrieving the signing url it gives back an unexpected error. Not sure what is the issue. { "roles":[ { "id":"Signer1", "type":"SIGNER", "index":0, "signers":[ { "firstName":"Signer", "lastName":"1", "email":"[email protected]", "language":"en", "title":"" }], "name":"Signer1" }], "documents":[ { "approvals":[ { "role":"Signer1", "fields":[ { "id":"[Signer1.Capture1]", "page":0, "subtype":"CAPTURE", "extract":true, "type":"SIGNATURE" }], "name":"[Signer1.Capture1]" }], "name": "Test File" }], "name": "Test Package REST", "type":"PACKAGE", "language":"en", "description":"New Package", "autoComplete":true, "status":"SENT" }

Thanks, that works perfectly!

Awesome! Glad to help! :)
