Custom App: How to connect from an earlier module?

[Henrik_Poulsen]

Hello Community

• I’m building a custom app in Make.com and need some help.

I want to take the audio output from an ElevenLabs module (which runs before this step) so that I can send the same audio file via an API call to Acast. (Acast Open API)
Like this:

I have made it work in postman (incl. file upload), but something is wrong in make.com

My code:
{
// Pre-processing step: Convert the buffer to a file.
“preprocessing”: {
“convertBufferToFile”: {
“input”: “{{parameters.audio}}”,
“output”: “convertedAudioFile.mp3”
}
},
// Upload step: Use the converted file.
“upload”: {
“url”: “/long key ;-)/episodes”,
“method”: “POST”,
“formData”: {
“title”: “{{parameters.title}}”,
“audio”: “{{convertedAudioFile.mp3}}”,
“status”: “draft”,
“summary”: “{{parameters. Summary}}”
}
}
}

Could you please guide me on how to achieve this?
Thanks in advance for your help!

Best regards,
Henrik

You need to have two fields with types filename and buffer.

[
    {
        "name": "name",
        "type": "filename",
        "label": "Name",
        "semantic": "file:name"
    },
    {
        "name": "data",
        "type": "buffer",
        "label": "Data",
        "semantic": "file:data"
    }
]

For more information, see Buffer | Make Developer Hub

Hope this helps! Let me know if there are any further questions or issues.
