For the most part, using ImportJSON works well—it’s a low effort way of pulling data from any API’s GET endpoint and storing that data in a sheet for further parsing and filtering. But, there was a flaw: Zendesk’s API calls are paginated and limited to 100 results per page. That meant that we needed to add a new ImportJSON() formula every 100 rows to get all of our data.
This follow-up guide goes the extra step—not to feed a big JSON file into ImportJSON, but to write a script that does everything, including pagination. And, as an added bonus, is easier on your API rate limit.
