It's a great tutorial but in the last step you miss to convert the content of the response before witing the file.
This could be a way (import base64):
attachment_content = response.json()['contentBytes']
decoded_content = base64.b64decode(attachment_content)
# Save the file
with open(attachment_name, 'wb') as file:
file.write(decoded_content)
file.close()
Bye

Thank you so much for adding this extra bit! I was pulling my hair out

[@djosue27]

Absolutely amazing! Even MS Documentation doesn't illustrate this as easily

[@motuada]

It helped a lot! I had problems at the beginning because I was filtering a specific message. I removed it from the filter and it worked for all messages. I also applied the Base64 tip. Thank you for sharing.

Insanely helpful video - can not thank you enough! Been banging my head against a wall for weeks trying to get this to work and this video finally made it happen. Only thing I did have to adjust at the end when you are setting the “download_attachment_endpoint” it needs (or mine did at least) a “/$value” at the end of that variable so I would get the actual file contents rather than just another JSON string. So helpful - thank you again!

Thanks scott5957, this fixed the unreadable files issue others have been noting.

[@rahulshah1408]

Thank you. That was my other missing puzzle piece.

[@CLGFM]

Finally able to read my mailbox emails, the other tutorials show you only to oauth via browser to authenticate which is useless for service scripts. Thank you.

This was extremely valuable in understanding how to work with the Graph API! Thank you so much for this content.

[@rahulshah1408]

Thank you for the step by step. I am new to python (former database admin with zero coding) and am having to google each line of code I am writing. This has been amazing. out of convenience, do you have a google drive or public github to access the code example?

[@sheepinriver]

Really helpful !! Just wondering does that Mail.Read permission allow read all user mailboxes ? That is the permission very very hard to get unless you are an IT administrator.

[@xFree23Stylex]

Thank you for your help!

[@Nova04550]

I think that's giving app permissions to every mailbox! Probably best to use delegated permissions and then authenticate on behalf of a user.

getting KeyError: 'value' for line 54
for attachment in attachments['value']:

[@magueritemichima6818]

hello Sir , great video , how can i get the code ?

[@MrArjunrajan]

I am getting an error as "/me request is only valid with delegated authentication flow." during subscription call.

[@momoViPRuS]

you WOW

[@cristhiansevilla4091]

when I tried to run the code, this message return {'error': {'code': 'ErrorAccessDenied', 'message': 'Access is denied. Check credentials and try again.'}}

[@JonathanDuque-d5z]

I get unreadable files

[@hemanthbanty6187]

How to download the file to specific folder path rather than the script place.

[@srp9819]

why are you not getting a option on the browser to authorize the graphApi ,
is there a way to by pass that , so that we can run the script any time with a scheduler , without any intervention ?

[@bernardmwanza1628]

my script does not have that browser auth thing, once you have the app secret, appclientid and tenantid hardcoded in the script, you can schedule it using windows task manager

[@RohitKumar-yz3eo]

Can you please tell how to do that

[@abhilashgaddam7836]

I am getting API response 403 what would I do?

[@bernardmwanza1628]

that is a permission problem, you have not assigned your app registration correct permission to access the resources you are requesting.

[@juanjoseospinaduque4524]

@@bernardmwanza1628 Hello sir, at the moment i count all the permissions but im still getting this error "'message': 'Insufficient privileges to complete the operation", i need some special from de administrador o not? thx!

[@SANDRO2464]

{'error': {'code': 'ErrorAccessDenied', 'message': 'Access is denied. Check credentials and try again.'

[@Danips88]

same mistake u.u

[@vamsipreetham6224]

I am getting 401 error why this is coming

[@bernardmwanza1628]

Your code. Is it correct

[@vamsipreetham6224]

The same as your followed each step carefully but getting 401 error

[@bernardmwanza1628]

Although 401 error is usually because of permission issue. Have u assigned and granted your app the correct application permission ?

[@bernardmwanza1628]

You can test the code, step by step, first very if u can get the access token, then next verify if u can get the entire json response for a particular resource instead of the custom filtered one.
