Generate Invoice PDF via Airtable API
Create invoice PDFs using the Airtable API without a paid plan. Pass a RecordId as a GET parameter, fetch properties, and replace Airtable data in an HTML template with Nunjucks. The HTML converts to a PDF and is returned.
Generate Email with ChatGPT
Automate email creation and sending. A CRM link generates an email body from a ChatGPT prompt with dynamic parameters. The native email client opens with the generated text.
HTML Form with Success Page
Create an interactive HTML landing page with a form. The function returns an HTML page via GET. The form submits via POST and returns a success page. The HTML is divided into a layout and partials, composed with Nunjucks.
Export Airtable as JSON
Export Airtable data as a JSON object. Linked tables are resolved, including all properties. Caching minimizes API calls, and the depth of table links can be defined.
