I have been able to successfully connect to Asana by using two resources (attached at the bottom) and extract a list of task names and custom field names, but I have been unsuccessful in using the JSONFormatter, JSONFlattener, and the JSONExtractor tools to create a list of tasks and their corresponding custom field values for a specific Asana project. If anyone is experienced in working with the Asana API to collect this kind of data from a particular Asana project, I’d be really appreciative of any helpful tips to create a final output of a project’s tasks and their custom fields. Thank you so much!
