Legacy (v0)
Create a legacy theme
Creates a legacy MySite theme and returns it. name is required and must not match any of the company’s existing MySite theme names, compared case-insensitively; a taken name returns 422 and leaves the existing theme untouched. To change an existing theme, use PATCH /api/legacy_themes/{id}. Send template.content, template.stylesheet, and template.head to give the new theme its own template, which is published immediately. public defaults to true; a public theme appears in the member theme picker and becomes the company’s default MySite theme when none is set yet. Send public as false for a private working copy. Returns 422 with validation errors when the theme cannot be saved. Requires a company admin Bearer token; admin users, company API tokens, and partner tokens also need the my_site_themes update permission.
