Question

How to download PDF after API conversion

Hi,

I've been trying to use Adobe PDF Services API to transform a .docx to .pdf. I used the exemple Postman colection following the given steps (https://documentcloud.adobe.com/document-services/index.html?_gl=1*1ckwf6v*_gcl_aw*R0NMLjE2NTQ3ODE0MDEuQ2p3S0NBand0SWFWQmhCa0Vpd0FzcjctYzhVbUdFY05UcjJ0NmFjenZNNXRpQzVuOHFvRHRROENuOE1BenlHNUJTLV9yYm5zSWJySmdob0NMeWtRQXZEX0J3RQ..#how-to-get-started-) and it seems to work fine. The problem is that I can't manage to get the pdf from the response. It seems to have a PDF in octet-stream, but no matter how I try to save it, I don't get a PDF.

For exemple, if I try to save all the response body and change the file name to .pdf, it opens a PDF with the right number of pages, but completly empty. That happens even if I keep only the part between %PDF-1.7 and %%EOF in the file.

 

The response I get from the GET request has the following structure in the body:

 

--Boundary_96548_2076176993_1654878435333
Content-Type: application/json
Content-Disposition: form-data; name="contentAnalyzerResponse"

Ps: I tried the same thing in python and got same error. I also tried with a .xlsx file, same thing.

If someone can give me some light, thank you very much!

    That isn't a PDF. It's a multipart response that INCLUDES a JSON and PDF; the PDF must be extracted from it.

    Following up: It seems that the problem is not in the "saving the PDF" part, because if I just download the answer and save as .pdf it will be recognized as a PDF with the right number of pages and the right author. However the document is still blank. I've tried oppening in Edge, Google Chrome and Adobe Acrobat online, all blank. I've also tried with different docx and even an image. They all seem to have the right format (number of page and landscape orientation for the image), but all blank.
    I suppose that there is some kind of problem or encription in the PDF, but I was unable to recognize it.
    I'll be thankfull if anyone has any idea of what is happening.

      I am having exactly the same issue when using the POST documentGeneration endpoint.

       

      This is the response I am getting (truncated - full response in the file attached):
