Today, we’re releasing the latest Slides API tutorial in our video series. This one goes back to basics a bit: adding text to presentations. But we also discuss shapes—not only adding shapes to slides, but also adding text within shapes. Most importantly, we cover one best practice when using the API: create your own object IDs. By doing this, developers can execute more requests while minimizing API calls.
insertText requests to tell the API to add text to slides. This is true whether you’re adding text to a textbox, a shape or table cell. Similar to the Google Sheets API, all requests are made as JSON payloads sent to the API’s
objectID) on a slide:
"text": "Hello World!n"
Adding shapes is a bit more challenging, as you can see from itssample JSON structure:
Placing or manipulating shapes or images on slides requires more information so the cloud service can properly render these objects. Be aware that it does involve some math, as you can see from the Page Elements page in the docs as well as the Transforms concept guide. In the video, I drop a few hints and good practices so you don’t have to start from scratch.
Regardless of how complex your requests are, if you have at least one, say in an array named
requests, you’d make an API call with the aforementioned
batchUpdate() method, which in Python looks like this (assuming
SLIDES is the service endpoint and a presentation ID of
For a detailed look at the complete code sample featured in the DevByte, check out the deep dive post. As you can see, adding text is fairly straightforward. If you want to learn how to format and style that text, check out the Formatting Text post and video as well as the text concepts guide.
To learn how to perform text search-and-replace, say to replace placeholders in a template deck, check out the Replacing Text & Images post and video as well as the merging data into slides guide. We hope these developer resources help you create that next great app that automates the task of producing presentations for your users!
