Platform-Specific Content

When creating or updating posts, you can provide per-platform content overrides via the platformContent object. If omitted, the main text field is used for all platforms. The main text field is used as the LinkedIn text. To override text for other platforms, include them in platformContent. For threads (Twitter, Threads, Bluesky), separate each post with double line breaks (\n\n) in the text field and set isThread: true.
