Sending File in WhatsApp Sandbox

[ahmetkocadogan]

I am sending a pdf file in whatsapp sandbox, but file is not received. And i got no error or exception while sending.

Is it a bug? Or whatsapp sandbox does not allow sending files?

Sending image and location is working.

Sending a message via the WA sandbox works correctly (I tested via direct API call):

curl -X "POST" "https://conversations.messagebird.com/v1/send" \
-H "Authorization: AccessKey dummy" \
-H "Content-Type: application/json" \
--data '{ "to":"dummy", "from":"dummy", "type": "file","content": { "file": {"url": "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf"} } }'

and I correctly got the pdf file on client

I am using the C# SDK.

Let me try again, i'll post the result

@dandronic This is what i get from ngrok inspect. And i didn't receive the file. I deleted some parts.

I think there is a problem with that specific pdf (or type). If I send another one (https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf) it works correctly, but the one you are sending it indeed does not get through). I'll research to see if there are any known restrictions/issues with pdf files. Can you do a test with sending https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf ?

[dandronic]

The file you are trying to send https://qconlondon.com/london-2017/system/files/presentation-slides/microsoft_bot_framework_best_practices.pdf is returning a data gzip compressed file/stream. This is something that MessageBird does not currently support (it will be added in the next weeks/months). That's why it is failing. Host the file on a non gzip server and you should not have any more problems.

Thanks. I'll try your pdf file, and close the issue if it succeeds.
