Frequently Asked Questions

What is Fill automation and how will it help my business?

Fill automation means using Fill templates to automatically populate, send, and collect signatures on documents. It removes manual data entry, speeds approvals, and reduces errors so teams close deals, onboard people, and process vendors faster.

How does viaSocket connect Fill to my existing apps?

viaSocket links your CRM, forms, HRIS, accounting, and storage apps to Fill using no-code workflows. You map fields once, then data flows automatically: create a document, send for signature, and route the signed file where you need it.

Can I use AI to populate or verify documents?

Yes. AI-enabled automation via viaSocket can extract, normalize, and enrich data from emails, forms, or documents before sending it to Fill—so addresses, clauses, pricing, and other fields are filled accurately without manual review.

Is my data secure when using Fill with viaSocket?

Yes. Connections use secure transfers and role-based access so only authorized systems and people can send or view documents. You control templates, who signs, and where signed files are stored.

Do I need templates or technical help to get started?

No technical work is required. Create Fill templates (or use existing ones), map source fields in viaSocket, and activate the workflow. You can preview documents before sending and adjust mappings anytime.
