Coupler.io is an add-on to Google Sheets that allows to pull data from various apps to Google Sheets on a set schedule with no coding required.
Any third-party exchange on Directual is organised through API-endpoints. Thus, you go to API builder and create new endpoint where you can choose fields which will be available for reading, also you can setup filtering and sorting.
Go to G suite marketplace and install add-on to your Google-account. Then, open Google Spreadsheet, click Add-ons – Coupler.io – Open dashboard.
In Coupler dashboard choose JSON client as a data source:
Then, paste your API-endpoint URL to JSON URL. Click 'Show advanced'. You'll find a field 'URL query string' there. Type to that field pageSize: N, where N is a number of objects which Spreadsheet will receive (by default pageSize = 30).
Coupler.io will automatically grab data from Directual API-endpoint (with a certain schedule which you can setup).
If your API-endpoint contains links or arrayLinks, Coupler.io will map the objects to flat table.
