Example of multipart request for custom greeting

[cbzink]

I'm attempting to create a custom greeting as outlined in the docs: https://developer.ringcentral.com/api-docs/latest/index.html#!#RefCreateUserCustomGreeting. Unfortunately this is failing using both a WAV and MP3 file with a 415 Unsupported Media Type error. Below is an example of my code:

$multipartRequest = $rcsdk->createMultipartBuilder()->setBody([
    'type' => 'Voicemail',
    'answeringRule' => [
        'id' => '[redacted]'
    ],
])->add(fopen('test_greeting.mp3', 'r'))->request('/restapi/v1.0/account/~/extension/[redacted]/greeting');

$response = $rcsdk->platform()->sendRequest($multipartRequest);

Could you provide a working example of createMultipartBuilder for this use case? Thanks!

The following CURL request works perfectly fine with my MP3 file, so the functionality is clearly there and the API endpoint works leading me to believe it's definitely an issue with the PHP lib itself.

curl -i -X POST -H "Content-Type: multipart/mixed" -H "Authorization: Bearer [redacted]" -F "json={'type': 'Voicemail', 'answeringRule': {'id': '[redacted]'}};type=application/json" -F "binary=@test_greeting.mp3" https://platform.devtest.ringcentral.com/restapi/v1.0/account/\~/extension/[redacted]/greeting

I don't think it is possible with this SDK. Becuase the SDK only supports multipart/form-data:

ringcentral-php/src/Http/MultipartBuilder.php

Line 146 in f27044f

$headers = array('Content-Type' => 'multipart/form-data; boundary=' . $stream->getBoundary());

multipart/mixed is required in order to update custom greeting audio.

@vyshakhbabji What do you think?

You can send any custom request if you assemble it manually.

@kirill-konshin Yes I agree. Currently user has to do it the hard way.

And making updating greeting audio support multipart/form-data is in our backlog.

So for @cbzink's original question:

Could you provide a working example of createMultipartBuilder for this use case?

The situation is that createMultipartBuilder cannot be used due to incompatible MIME type, however, per @kirill-konshin, the request could be built manually:

You can send any custom request if you assemble it manually.

Can we provide an example of how to do this manually or a pointer to a multipart/mixed library to do this?

I did some Google searches and found CkMime but it is a commercial library:

I also found an unsuccessful reference to using Swift Mailer. At the time, multipart/mixed wasn't possible with v3 and waiting for v4 was recommended. They are on v6 now so it could be viable:
