Grabzit Callback - Esempi?
Poni domande su come acquisire o convertire pagine Web o HTML into immagini, documenti CSV, PDF o DOCX nonché su come convertire i video into GIF animate che utilizzano la nostra API.
I'm using this service to generate a PDF from HTML of a contest entry form but now I've enhanced the submission process to allow submitting up to 10 entries at one time. As generating the PDFs in a loop takes roughly 2min (while the user sees a spinning GIF but can't do anything and just has to wait) I'd like to explore the callback functionality but can't find good examples. I know my PHP handler must be publicly accessible but would much appreciate some sample code.
Ciao,
There is some indepth documentation on callback handlers and a working example in the PHP demo.
Cordiali saluti
