What is Api2pdf?
Api2pdf is a specialized service that simplifies the process of converting HTML, URLs, and various file formats into high-quality PDFs. By integrating this tool as part of your Openclaw Skills library, you eliminate the need to maintain complex, resource-heavy PDF generation libraries locally. It provides a scalable API for creating professional documents like invoices, reports, and certificates on the fly.
This skill uses the Membrane framework to manage authentication and connectivity. This means developers can focus on document logic rather than handling API keys or token refreshes. With support for Chrome-based rendering and LibreOffice conversions, it ensures high fidelity for both web-to-pdf and office-to-pdf workflows.
Api2pdf Use Cases
- Converting dynamic web pages or raw HTML templates into downloadable PDF reports.
- Merging several PDF documents into a single file for streamlined record keeping.
- Converting Microsoft Office documents (Word, Excel, PowerPoint) into PDF format programmatically.
- Protecting sensitive PDFs with passwords or adding custom watermarks for branding.
- Generating barcodes and QR codes to be embedded directly into generated documents.
How Api2pdf Works
- The user installs the Membrane CLI to act as the interface between the local environment and the Api2pdf service.
- Authentication is handled through a secure login flow that stores credentials safely in the Membrane cloud, not on the local machine.
- The user identifies the required action (e.g., convert-url-to-pdf) by searching the available action list within the connection.
- Commands are sent via the CLI or an AI agent, passing necessary parameters like source URLs or HTML strings.
- Api2pdf processes the request in the cloud and returns a URL to the generated document, which is stored temporarily for 24 hours.
Api2pdf Setup
To integrate this with your Openclaw Skills, start by installing the Membrane CLI:
npm install -g @membranehq/cli
Log in to your account:
membrane login --tenant
Search for the Api2pdf connector and establish a new connection:
membrane search api2pdf --elementType=connector --json
# Use the ID from the search results
membrane connect --connectorId=CONNECTOR_ID --json
