• Basic configuration: Use this setting if the entire address is provided as a single column.

• Advanced configuration: Switch to the advanced setting mode if individual parts of an address are specified. Any fields that are left blank, or values that are null will be ignored. As this is more specific it will tend to produce better results than the full address version.
  
  

  Tip
  You can also concatenate a split up address together by using the Calculated Field step, and stringing each field with a plus (+) operator.

• API Key: OpenCage provides an API key which is necessary to run the geocoding step. To obtain this key, see: https://geocoder.opencagedata.com/ 

• Preview Mode Row Limit: The API key has a usage limit to the number of times you can use the API, depending on your pricing package . These can be consumed quickly, while testing, and once the limit is exhausted, you will not be able to use this step(see https://geocoder.opencagedata.com/pricing for more information). To ensure that you do not use up your limits consume the usage limit too quickly during testing, this field can be used to specify the number of times you could use the key in a preview run. If this value is set to 0, then no limit will be applied. The number you specify here will affect the number of rows in the data preview panel. Note, however, that this setting will not be applied when the flow is published and run.
