Has anyone uploaded a PDF to Content Builder using REST? I think this is the Route, just not sure exactly how it works.

POST /asset/v1/content/assets

I see a few properties:

Data    object      Property bag containing the asset data
Content string      The actual content of the asset

Looking to upload the PDF in Content Builder for use as an Email Attachment.

As per your post I was able to upload a pdf file into sfmc content builder. It took me a little while to gather all the necessary attributes but it is all available in REST Reference API.

Here are the steps and things to consider:

  • Make sure the API user account has Assets read and write access.
  • Your pdf file that needs to be uploaded to the content builder needs to be Base64Encoded which you can convert using this website.
  • If you wish to upload the pdf file to a specific folder within content builder then you need to specify the folder ID and name within the category object attribute.
  • Also proper assetType needs to be set for specific type of file - in your situation it is name as pdf and id as 127.
  • Also I am using Postman to test this scenario.

  • Below is the sample request which works successfully:



{ "name": "pdf name to be uploaded", "assetType": { "name": "pdf", "id": 127 }, "category": { "id": 123456 (ID of the folder) , "name": "name of folder where pdf is uploaded" }, "file": "xxxxxBase64Encoded-Filexxxxx" }

  • On an unrelated note: for id/name attributes like assetType and category, only the id is required. The name is useful for display purposes on GET but will be ignored on POST/PUT/PATCH. Oct 30, 2017 at 13:21
  • Thank you for your response. I was able to successfully add a file. Oct 30, 2017 at 19:24
  • Just a friendly comment, you don't need to pass category name is the payload as id is all you need
