Integrate eSigning with API | DealBuilder

Integrate digital signing with DealBuilder's API

Do you want to embed digital signing in your own system or software? DealBuilder offers a flexible and powerful e-signing API that makes it easy to automate the entire document flow — from generation to signing and reversing status via webhooks.

Our esign API gives you full control over how documents are created, customized, and signed — whether you're working with ready-made PDFs or template-based documents.
‍

Three Ways to Use DealBuilder's Signing API

Our esignature API supports several different integration methods, adapted to different needs and workflows. Here are three concrete ways you can use the DealBuilder API:

1. Automatic PDF signing

Submit a ready-made PDF with simple parameters such as signers and metadata. You select a template ID that controls deadlines, signing method, notification, and access. DealBuilder automatically sends the document for signing and updates you with webhooks once the document is signed.

Typical usage:
— Order confirmations
— Contracts generated in other systems
— Documents to be digitally signed only, without changes

2. Automated document generation from template

External systems send data (e.g. products, prices, discounts, and terms) to DealBuilder, which generates a complete document from a template and sends it for signing. This gives you an automated and professional flow from data to finished signed document.

Typical usage:
— Offers and agreements generated from a CRM
— Onboarding of new customers
— Order forms or service agreements

3. Semi-automatic flow with manual quality assurance

For situations where the document should be reviewed before it is sent out, DealBuilder can receive data from a remote system and fill out the document -- but allow the user to make final adjustments manually. Then the document can be easily sent out for signing.

Typical usage:
— Complex bidding
— Personalized HR documents
— Contracts that vary from customer to customer

With DealBuilder's signing API and webhook support, you get a complete toolkit for automating document processes:

— Send data from own systems: Pre-fill documents automatically via GET requests to DealBuilder
— Receive updates: Get notified in real time when a document is sent, signed or rejected
— Synchronize products: Keep product data up-to-date between DealBuilder and other systems
— Connect Forms: Allow customers to fill out a form and have a quote or appointment sent automatically
