API for Internal Direct Connectivity

Automate Your Print-and-Mail Workflow Directly from Your Software

The DocuSend REST API provides organizations with a simple way to automate the printing and mailing of business documents directly from their internal systems. Instead of downloading PDFs, uploading them to a website, printing them in-house, or working with multiple vendors, your application securely sends documents to DocuSend through the API, where they are automatically printed, prepared, mailed, tracked, and delivered.

Automate Your Print-and-Mail Workflow Directly from Your Software

What Is an Internal Print and Mail API?

An internal print-and-mail API allows your business applications to communicate directly with a professional mail production facility.

Instead of an employee having to:

  • Download a PDF
  • Print the document
  • Fold pages
  • Insert them into envelopes
  • Apply postage
  • Deliver mail to the post office

your software performs a simple API request, and DocuSend handles the entire production and mailing process automatically.

This allows your employees to focus on higher-value work instead of repetitive mailing tasks.

Why Companies Use Direct API Connectivity

Many organizations generate documents from systems such as:

  • ERP software
  • Accounting software
  • Utility billing systems
  • Healthcare applications
  • Insurance platforms
  • Financial systems
  • Government applications
  • CRM software
  • Property management systems
  • Membership management platforms
  • Legal practice management software

These systems already generate PDF documents. Rather than creating another manual workflow, the DocuSend API allows those PDFs to be transmitted automatically for printing and mailing.

There is no need for employees to log into another application or upload files manually.

Eliminate the Cost of Maintaining an Internal Mailroom

Operating an internal mailroom often involves significant hidden expenses, including:

  • Printers and production equipment
  • Folding and inserting machines
  • Envelope inventory
  • Paper storage
  • Ink and toner
  • Postage management
  • Equipment maintenance
  • Employee labor
  • Training
  • Equipment replacement
  • Learning and managing USPS mailing regulations

With DocuSend, you only pay for the mail you actually send.

  • No minimum monthly volume
  • No long-term equipment leases
  • No inventory management
  • No dedicated mailing staff required

Your organization gains enterprise-level mailing capabilities without the operational overhead.

From Manual Workflow to Automated Delivery

Without an automated mailing solution, a typical workflow may involve several manual steps after a document is created, including:

  • Exporting or locating the PDF
  • Printing documents
  • Folding and inserting pages into envelopes
  • Applying postage
  • Preparing mail for pickup or delivery to the postal service

Using the DocuSend API, these steps can be incorporated into a single automated process. Once the document is generated, your software submits it directly to DocuSend, where it is prepared and mailed according to your selected options.

Perfect for Event-Triggered Documents

Many mailing services work well for scheduled monthly jobs.

However, businesses often need to mail documents that cannot be scheduled because they are generated by specific customer or business events.

Since these documents are generated unpredictably, maintaining an internal mailing process becomes inefficient.

The DocuSend API processes documents immediately whenever your application creates them, regardless of volume or frequency.

Scale Without Limits

Business mailing volumes often fluctuate dramatically.

One day you may send five documents.

The next day you may send five thousand.

DocuSend is built to handle both scenarios without requiring infrastructure changes or additional staffing.

Benefits include:

  • No minimum quantities
  • No maximum volume restrictions
  • Automatic scaling
  • Consistent processing
  • Enterprise reliability

Whether your organization sends occasional notices or millions of pages annually, the same API supports your workflow.

Secure Document Delivery

Business documents frequently contain confidential customer information.

The DocuSend API uses secure transmission methods to help protect your documents during submission and processing.

Organizations can confidently automate the mailing of sensitive documents such as:

  • Financial statements
  • Utility bills
  • Insurance documents
  • Medical communications
  • Tax documents
  • Legal notices
  • Customer invoices

Easily Integrate with Existing Applications

The REST API is designed for straightforward integration with virtually any modern programming language or development platform.

Typical integrations include:

  • Internal business applications
  • Customer portals
  • Accounting systems
  • Billing software
  • ERP platforms
  • CRM systems
  • Web applications
  • Desktop software
  • SaaS platforms
  • Custom enterprise software

Once integrated, printing and mailing become another automated business process.

Typical API Workflow

The process is simple:

  1. Your application generates a PDF.
  2. Your software submits the document through the DocuSend REST API.
  3. DocuSend validates and processes the job.
  4. Documents are printed using professional production equipment.
  5. Pages are folded, inserted into envelopes, and prepared for mailing using automated first-class postage.
  6. Mail enters the postal stream.
  7. Your application can retrieve job status and tracking information through the API.

No manual intervention is required.
