Power Automate HTTP request convert Word to PDF

kelseyvdheijden · November 5, 2024, 1:22pm

Hi everyone,

I would like to convert a Word (.docx) file with a HTTP Post request in Power Automate in order to convert the file to PDF. I’m able to get is working through Postman, but I don’t know how to do it in Power Automate. I want to avoid the Plumsail connector because if I do so the user has to insert the API-key when connecting to the flow. Can you help me please?

Current setup:

URL: https://api.plumsail.com/api/v2/convert/docx-to-pdf
Headers:
- Authorization: *
- Content-Type: application/json
- Accept: application/json
Body: [SharePoint file content]

Many thanks in advance!

Hello @kelseyvdheijden,

These settings look correct. Do you have any errors when running the request?

You can additionally test the settings here.

Hello @kelseyvdheijden,

It is necessary to form a multipart content in the body

for example

{
 "$multipart": [
   {
     "headers": {
       "Content-Disposition": "form-data; name=\"File\"; filename=\"application\""
     },
     "body":
   },
   {
     "headers": {
       "Content-Disposition": "form-data; name=\"Data\""
     },
     "body": 
   }
 ],
 "$content-type": "multipart/form-data"
}

Also, use Compose to convert base64 to bytes
