Solved: Re: How do you return pdf content from an API to P...

Hmp-pt · ‎06-09-2020

Hi,

Does anyone have experience with this?

Here is the output from my HTTP GET request. The API says the pdf file is returned.

I'm trying to display this file in a pdfviewer within Power Apps.

I return the output to Power Apps using a Response action, put the result of the flow into a collection and then set the document property on the pdfviewer like so:

But it says it expects a Blob.

How do I return that?

Do I have to save the file somehow and then use the GetAttachmentContent action?

I tried lots of ways but with no success thus far.

Please help!

Watch the video. He is using Flow to get the file content via a connector (API) also.

Take a look at this video tutorial by Paul Culmsee. It returns a PDF from Flow to display using the Response action. It should give you what you need.

Thanks @Pstork1 .

What do I return though and how? All the videos I've seen are obtaining the pdf content from files stored in Sharepoint and using the GetFileContent/GetFileAttachment action to get the content.

I have the output from the API.

Thanks again.

Hi @Pstork1 and @Hmp-pt

Would you be able to guide me on the solution. I have an API that downloads a pdf file. I would like to display the PDF in powerapps. I watched the video, but they are using sharepoint to get the file.

Regards,

drombley

Once you have retrieved the file in the flow the process is the same. Where is the file stored? and what do you mean that it downloads the file? Does the API return the file or just download it to your local workstation?

The API call downloads the pdf file to the local workstation. Can the flow handle that?

Pstork1 · ‎10-14-2023

A cloud flow can only access files on the desktop through a network share and an on-premises gateway. That would require a Premium license and you probably won't have a network share created for the location where the file is downloaded. So it is theoretically possible, but only if you have the right licensing and all the other pieces are in place. So in general I don't think you will find a cloud flow can handle that. You might want to try a Power Automate Desktop flow instead. Taht runs on the local workstation and has access to downloaded files more easily.
