Send Voice Message
Send a voice note to a LinkedIn chat from a public audio URL in .mp3, .m4a, .ogg, or .wav format, up to 5 MB. Target an existing conversation with chat_id or start a new one with provider_id, and add an optional text caption or campaign tracking ID. The call fails if the audio URL is invalid or the format is unsupported, and each voice note counts against your daily message limit. Generate audio with any text-to-speech provider and host it using upload_media.
Example prompt: Send a voice note from this audio URL to my chat with Diana, with the caption 'great to connect'
