1. Prepare project

Choose the fitting client lib for your language or generate / build your own by the OpenApi (Swagger) description.

2. Design your PDF in the playground

Go to 🐢PdfTurtle-Playground, put an example model as JSON and design your PDF. Download the bundle as ZIP file and put it in your resources/assets.

!PdfTurtleBundle-Workflow

3. Call the service with the client and your data

Send a request to a PdfTurtle instance with your bundle and your model. You will get a rendered PDF.

And thats it.

Hint: You can split your bundle

If you want to have the same header for all documents, you can create a ZIP file with with only the header.html and the required assets. Now you can call the Service with multiple bundle files. The service will assemble the files together. Single files can be send as bundle-component without compressing to a ZIP file. All files with other names than "index.html", "header.html", "footer.html" and "options.json" will be put to the folder "/assets/".

PdfTurtle Playground

You can write and test templates with the builtin playground.
