Connect WordPress with Cal ID
Add your Cal ID booking page to WordPress with a free plugin (block or shortcode) or a one-line embed.
Cal ID is a free WordPress booking plugin that adds appointment scheduling to any WordPress site. Install it from the WordPress plugin directory, then place your Cal ID booking page with a block or the [cal_id_embed] shortcode, in an inline, modal, or floating layout. Visitors book appointments, classes, or calls in seconds, logged-in users get their details prefilled, and payments run through Stripe, Razorpay, or PayPal automatically after each booking. It syncs two-way with Google and Outlook so you never double-book, keeps your CRM in sync, and matches your brand color and button text. Prefer not to install anything? Paste the same booking page as a one-line embed instead.
