The output format for your data:
json_meta - The current default format, where each payload contains a full JSON document. It contains metadata
and an "interactions" property that has an array of interactions.
json_array - The payload is a full JSON document, but just has an array of interactions.
json_new_line - The payload is NOT a full JSON document. Each interaction is flattened and separated by a line
break.
If you omit this parameter or set it to json_meta, your output consists of JSON metadata followed by a JSON
array of interactions (wrapped in square brackets and separated by commas).
Take a look at our Sample Output for File-Based Connectors page.
If you select json_array, DataSift omits the metadata and sends just the array of interactions.
If you select json_new_line, DataSift omits the metadata and sends each interaction as a single JSON object.
