Gravity Forms and Formstack Documents Integration: Setup Options and Workflows

Blog
By blogjoker

The best setup is usually Gravity Forms for data, Formstack Documents for files, and Zapier or Webhooks as the bridge. Gravity Forms collects the answers on your WordPress site. Formstack Documents turns those answers into clean PDFs, contracts, quotes, letters, invoices, or reports. The trick is picking the right connection method before you build everything twice. Nobody enjoys that.

TLDR: Use Zapier or Make if you want a simple setup with very little code. Use the Gravity Forms Webhooks Add-On if you want a cleaner direct path. A small clinic that processes 120 intake forms per week could save about 10 hours weekly if each generated document saves 5 minutes of manual copying. For example, a patient submits a Gravity Form, and Formstack Documents instantly creates a signed intake PDF and emails it to staff.

What This Integration Actually Does

Think of Gravity Forms as the friendly front desk. It asks the questions. Name. Email. Services. Dates. Prices. Weird pet name. Whatever you need.

Formstack Documents is the robot in the back office. It takes that data and drops it into a template. Then it creates a polished document. No copy and paste. No “final FINAL version 7.pdf” chaos.

Together, they can create:

  • Contracts from quote request forms.
  • Invoices from order forms.
  • Certificates from course completion forms.
  • Client intake packets from onboarding forms.
  • Proposals from sales forms.
  • HR documents from job application forms.

The form is the input. The document is the output. The integration is the conveyor belt.

Option 1: Use Zapier

This is the easiest path for most teams.

Zapier watches Gravity Forms for a new submission. Then it sends the form data to Formstack Documents. Formstack creates the file. Then Zapier can keep going. It can email the file. Save it to Google Drive. Add a row to Google Sheets. Ping Slack. Light a tiny digital firework.

Basic Zapier workflow:

  1. Create your form in Gravity Forms.
  2. Create your document template in Formstack Documents.
  3. Add merge fields to the template.
  4. Make a Zap with New Form Submission as the trigger.
  5. Choose Create Document Merge as the action.
  6. Map Gravity Forms fields to Formstack document fields.
  7. Test it with real sample data.

This works well if your team wants speed. It also helps if non-developers need to edit steps later.

The catch is… Zapier can get messy when flows grow. One form may turn into 14 steps. Then one field name changes. Suddenly your lovely workflow acts like a toaster in the rain.

Option 2: Use the Gravity Forms Webhooks Add-On

This option is cleaner. It can also be faster. Gravity Forms can send form data straight to a URL after submission. Formstack Documents can receive that data through its merge endpoint or API setup.

This is a good pick when you want fewer tools in the middle.

Basic Webhooks workflow:

  1. Install the Gravity Forms Webhooks Add-On.
  2. Create your Formstack Documents template.
  3. Find the merge URL or API endpoint in Formstack.
  4. Create a webhook feed in Gravity Forms.
  5. Set the request method, often POST.
  6. Map your fields.
  7. Submit a test form.

This setup feels more direct. It means fewer monthly app limits. It also gives you more control over the payload.

But it is less friendly for beginners. Expect to waste time on tiny things like headers, authentication, and field names. One capital letter can ruin your coffee.

Option 3: Use Make or Another Automation Tool

Make is great for visual builders. It lets you build a flow with bubbles and paths. It can pull data from Gravity Forms. It can send that data to Formstack Documents. It can also route the result based on rules.

For example:

  • If order total is over $5,000, send the proposal to sales.
  • If the form says rush order, store the PDF in a priority folder.
  • If the state is California, use a California contract template.

This is handy when your process has branches. It is also nice for teams that like to see the whole flow on one screen.

Option 4: Custom Code

This is the power tool option. Use it when your process is odd, large, or private.

A developer can use Gravity Forms hooks like gform_after_submission. When someone submits the form, custom PHP can send the entry data to Formstack Documents through its API.

This is best when you need:

  • Custom data cleanup before the document is made.
  • Strict security rules.
  • Special file naming.
  • Complex conditions.
  • No third-party automation middle layer.

The downside is clear. You need a developer. You also need someone to maintain it when APIs change. Code is not “set it and forget it.” Code is “set it, document it, and please do not let Dave edit it on Friday.”

How to Build the Document Template

Start with the final document. Not the form. This saves pain.

Open Word, Google Docs, or the Formstack Documents builder. Create the document you want. Add merge fields where form answers should appear.

Example fields might be:

  • {client_name}
  • {email}
  • {project_total}
  • {start_date}
  • {service_package}

Keep field names simple. Use clear labels. Do not use five versions of “Name.” You will regret it during mapping.

Then build your Gravity Form to match the document. If the document needs a billing address, the form needs one too. Simple, but easy to miss.

A Simple Contract Workflow

Here is a common setup.

  1. A client fills out a quote form on your WordPress site.
  2. Gravity Forms stores the entry.
  3. The integration sends the entry to Formstack Documents.
  4. Formstack creates a contract PDF.
  5. The PDF is emailed to the client.
  6. A copy is saved in Dropbox or Google Drive.
  7. The sales team gets a Slack alert.

That is a full admin process from one form submission. No one had to copy an address into a contract. No one had to rename a file by hand. Beautiful.

Smart Workflow Ideas

You can keep it basic. Or you can get clever.

  • Conditional templates: Send different documents based on form choices.
  • Approval steps: Create a draft first, then email it after manager approval.
  • Payment records: Add payment details from Gravity Forms payment fields.
  • File storage: Save every generated file to a client folder.
  • E-signature: Send contracts to an e-sign tool after creation.
  • Internal alerts: Notify staff when a high-value form arrives.

A service business could generate 300 proposals per month. If each proposal takes 8 minutes by hand, that is 40 hours of admin work. One full work week. Gone.

Common Mistakes to Avoid

  • Changing field labels after setup. This can break mapping.
  • Skipping test entries. Always test with messy real data.
  • Using unclear field names. “Field 7” helps nobody.
  • Forgetting file names. Use names like Contract ClientName Date.
  • Ignoring failed runs. Set alerts when an automation fails.
  • Sending private data without care. Use secure connections and proper access rules.

Which Setup Should You Choose?

Pick Zapier if you want easy setup and quick edits.

Pick Make if you need visual branching and more control.

Pick Webhooks if you want fewer tools between Gravity Forms and Formstack Documents.

Pick custom code if your workflow is special, sensitive, or large.

For most small teams, start with Zapier or Make. Get the process working. Watch it for two weeks. Then decide if you need a direct webhook or custom build.

Final Tip

Build one workflow first. Not five. Choose one form and one document. Make it work from start to finish. Then clone the pattern.

Gravity Forms and Formstack Documents can remove a silly amount of admin work. The setup is not magic. It is just clean field mapping, smart testing, and a workflow that does exactly what your team already does by hand. Only faster. And with fewer sighs.
