| Name | Required | Description | Default |
|---|---|---|---|
| message_board_id | Yes | Basecamp resource identifier | |
| subject | Yes | Message subject/title | |
| content | No | HTML message content. HTML rules for content: * Allowed tags: p, span, h2, h3, h4, br, strong, em, strike, code, a (with href attribute), pre, ol, ul, li, blockquote, mark, figure, figcaption, table, tbody, tr, th, td, div, bc-attachment. * Use <p> for paragraphs. Use <p><br></p> for empty line spacing between paragraphs. * Headings: use <h2>, <h3>, <h4> as appropriate. * Inline code: <code>text</code>. Preformatted blocks: <pre>text</pre>. * Ordered lists: <ol><li>...</li></ol>. Unordered: <ul><li>...</li></ul>. * Tables: <table><tbody><tr><th>Heading</th>...</tr><tr><td>Cell</td>...</tr></tbody></table> * To mention people: <bc-attachment sgid="{ person.attachable_sgid }" content-type="application/vnd.basecamp.mention"></bc-attachment> * Single image: <bc-attachment sgid="{ attachment.attachable_sgid }"></bc-attachment> * Image gallery: wrap multiple <bc-attachment sgid="..." presentation="gallery"> in a <div>. * Basecamp auto-enriches bc-attachment tags after saving (adds url, href, filename, content-type, etc.) — you never need to write those. * To consume less tokens, existing <bc-attachment> tags can be rewritten keeping only: sgid, presentation, caption. For mentions also keep content-type="application/vnd.basecamp.mention". Drop everything else including inner HTML. * Background highlights: <mark style="background-color: var(--highlight-bg-N);">...</mark> * Text color highlights: <span style="color: var(--highlight-N);">...</span> * For both, N is 1 (yellow), 2 (amber), 3 (red), 4 (pink), 5 (purple), 6 (blue), 7 (teal), 8 (near-white), or 9 (light gray). | |
