Using multiple templates

You may have a scenario where you want to build a PowerPoint using slides from multiple template PowerPoints.

To do this, you have to:

1. Include your template PowerPoint file as a "File" with your POST request to the API. Give your parameter name "files".

2. Include a reference with the name template_list to your JSON payload as below. template list contains template_id and template_name properties. The template_id will later be used by the JSON payload to define which template file is used for each slide. The template_name must be the same name as the filename sent with the form as the "files" parameter.

{
   "presentation":{
      "template_list":[
         {
            "template_id":1,
            "template_name":"template-1.pptx"
         },
         {
            "template_id":2,
            "template_name":"template-2.pptx"
         },
         {
            "template_id":3,
            "template_name":"template-3.pptx"
         }
      ]
      ....
      

3. At the JSON payload give template_id for each slide.

"slides":[
   {
      "slide_index":0,
      "template_id":1,
   ....   

You can't provide multiple template files and a single template file together as shown below.

//This syntax is not allowed.
{
   "presentation":{
      "template":"template.pptx",
      "template_list":[
         {
            "template_id":1,
            "template_name":"template-1.pptx"
         },
         {
            "template_id":2,
            "template_name":"template-2.pptx"
         },
         {
            "template_id":3,
            "template_name":"template-3.pptx"
         }
      ],
      ....

Sample JSON payload:

  "presentation": {
