Workflow : Action send HTTP - download and store PDF in return

[zkuun8]

Hello,

I’m looking to create an automated process using the WORKFLOW extension, with the goal of retrieving a PDF by sending an HTTP request.

Currently, the POST returns a response that I capture in WORKFLOW. However, this response is a download link for a PDF file.

My goal is to download this PDF and then add it to my Attachment's entity.

Unless I’m mistaken, this isn’t possible natively.

What approach do you recommend? Hook, Custom Services action, ... ?

Hi,

I'd create a custom Formula function that will download the attachment content. Your workflow action can obtain the link from the Send HTTP Request action response, write it into a formula variable. Then, your custom function will download the attachment by a given URL and create an Attachment entity. The function could return the attachment ID.

It's just on option. Maybe there're are better approaches for you.

You can also utilize a second Send HTTP Request action that will download the file. You can use placeholders when specifying the URL. Then, using a formula script, you can create an attachment record.

It's important to unset the variable with the file content at the end.
