Introduction

Penneo Collect lets you build online forms, collect data and files from your respondents, and turn each submission into a signed document, all through the API.

This overview explains the core concepts. Each feature then has its own page with the details and examples.

The flow

You create a form via the API. It describes the sections, fields, and signers you want.
You publish the form and share its public URL (or a prefilled link) with a respondent.
The respondent fills and submits the form.
The submission is sent to Penneo Sign for signing.
You retrieve the submitted answers and the signed PDF through the API.

Forms and submissions

Concept	What it is
Form	The reusable template you define. Identified by an `formId` (UUID).
Submission	One respondent's completed form. Identified by a `submissionId` (UUID).

A single form (externalId) produces many submissions.

ID	Identifies	You use it to
`formId`	The form	Update, publish, or archive the form
`submissionId`	A single submission	Retrieve the answers for that submission
`requestId`	A prefilled request	Retrieve the answers for that request

Where to go next

Getting Started — authenticate and create your first form end to end.
Forms — build forms: field types, signers, conditional logic, merge fields, options, and managing the form lifecycle.
Prefilled Requests — send a respondent a link that is already filled in, with signers attached and reminders enabled.
Submissions — list submissions and retrieve submitted data.

Base URL and authentication

All endpoints live under:

https://app.penneo.com/collect/api
