Hi Rykie,
I assume your question was about how to make it work faster. You can speed up querying by running queries in parallel as explained here: Iterate Web Request Performance
Also, sometimes APIs can accepts arrays of elements. For instance, one request can accept and process an array of product IDs instead one ID at a time. In this case, a request should be made with an array of IDs (e.g. 1000 elements) that is prepared in EasyMorph first.
To see whether the target API endpoint supports arrays, read the API documentation. Usually, it’s explicitly stationed when an endpoint can process multiple items at a time.
