SnapPDF + Webflow

What you can build

• Webflow Logic block: "SnapPDF Merge" as a native step.
• Legacy webhook support for pre-Logic sites.
• Cover-page generation from form field values (applicant name, role, date).
• Auto-email the merged PDF via Resend or SendGrid handoff.
• Store the PDF in the CRM (HubSpot, Salesforce) as a deal attachment.

Setup

1. 01
   In Webflow Logic, add a SnapPDF block

   Logic → New flow → Trigger: Form submission → Add step → search "SnapPDF". Pick Merge.
2. 02
   Map form fields

   Drag the uploaded-file fields into the Merge step's files[] parameter. Add a cover-page step with form values interpolated.
3. 03
   Authorize SnapPDF

   First use prompts for your API key. Webflow stores it as a secret.
4. 04
   Add a handoff step

   Resend, SendGrid, HubSpot — whatever you use. Pass the merged PDF URL or file.
5. 05
   Publish and test

   Submit a test form with sample files. Check that the merged PDF lands where expected.

Code example

Webflow Logic flow as pseudocode: form → merge → cover → email.

TRIGGER: Form submission (form_id: "vendor-intake")

STEP 1: SnapPDF → Merge
  files:
    - {{trigger.files.case_study_1}}
    - {{trigger.files.case_study_2}}
    - {{trigger.files.case_study_3}}
  preserveBookmarks: true

STEP 2: SnapPDF → Fill Form (cover-template.pdf)
  values:
    applicant_name: {{trigger.name}}
    company: {{trigger.company}}
    role: {{trigger.role}}
    submitted_at: {{now}}

STEP 3: SnapPDF → Merge (final)
  files:
    - {{step_2.pdf}}
    - {{step_1.pdf}}

STEP 4: Resend → Send Email
  to: ops@acme.com
  subject: "New vendor intake: {{trigger.company}}"
  attachment: {{step_3.pdf}}
