How to Create Multi-page PDFs

Use workflows to stitch multiple PDFs, JPGs, and PNGs, into a single multi-page document.

Inputs

Create a Workflow and use the + Add Input button to declare your inputs. These are the parameters that you'll supply to the API when you run your workflow.

Note: Available inputs can be found on the Create Multi-Page PDF tool page and the API parameters can be found on the API Reference page.

Each Inputs has:

• name  - used as references in your steps and API requests
• type  - the type of input you're supplying
  • text   
  • url   
  • number   
  • boolean  (true/false)
• required  - determines whether a run must supply this input

Multi-page PDF

Add a Tool step and select Create multi-page PDF from the list. Use the + ref drop-menu to add your inputs to their corresponding fields.

API Workflow Run

Send a POST request to the /v5/workflow_runs  endpoint, along with your workflow UID and a list of "urls": ["page1.jpg", "page2.png", "page3.pdf"] .

var data = {
  "workflow": "VymBYa7gMjW6JQ2njM",
  "inputs": {
    "urls": [
      "page1.jpg",
      "page2.png",
      "page3.pdf"
    ]
  }
}
fetch('https://api.bannerbear.com/v5/workflow_runs', {
  method: 'POST',
  body: JSON.stringify(data),
  headers: {
    'Content-Type' : 'application/json',
    'Authorization' : `Bearer ${API_KEY}`
  }
})

Note: Workflows can be created via the API as well. See Create a Workflow for more.
