When you run an API request, Data Fetcher transforms the response into records using the response data transformation and response field mapping. Sometimes this will produce more records than you want. You can limit how many records are output by setting the Max response records.
For example, if the API gives us this response:
But we only want the first record, we can set the Max response records to 1 and we will get:
Set the max response records
On the create request screen, click
to open the advanced options.
Under, Max response records enter the maximum number of records.
If you want to see the changes on the Response field mapping, you will need to refresh the fields.
