I searched thru community posts and also Tulip support site but I’m unable to find how to use query parameters in connector functions.

I have a boolean field in table called _ **ToolKit** _ and i would like to filter data based on data in this column (which can be yes or no). I’m using then this query to populate _ **Single select** _ widget.

I’m probably doing something wrong. When I test query I get error:  
“details” :“Unable to parse query string: extra param(s): ToolKit”  
“errorCode”: “InvalidQueryString”

Without parameters query works.

I have connector to tulip tables.

hello @ermingut, thanks for posting!! here’s a quick guide on how to filter the Table API Connector Function based on parameters.

1. run a Connector Function **GET** `https://{{instance_name}}.tulip.co/api/v3/tables/$tableID$` and find the **name** for the field in your Table you’d like to filter by:

2. add Query Parameters to your Connector Function **GET** `https://{{instance_name}}.tulip.co/api/v3/tables/$tableID$/records` as such:  
`filters.0.field = name of a Table column `  
`filters.0.arg = the value to compare to`  
`filters.0.functionType = comparison function`  
 ![Screen Shot 1](https://us1.discourse-cdn.com/flex020/uploads/agilemfg/original/2X/8/81d89a76b8d867569495617682391497ed59ff35.jpeg)

this will return the filtered Table Records based on the Filters provided. I would like to point out that you can add multiple filters by entering sequential filters and incrementing the index (where it’s set to 0 in the above example).

for further resources, I’d recommend looking at:

- [How to Use the Table API | Tulip Help Center - Support for Building Manufacturing Apps](https://support.tulip.co/en/articles/3983173-how-to-use-the-table-api)

- https://{{instance\_name}}.tulip.co/apiDocs

does this answer you question?? let us know!!

Hi.

Thank you @gio. This is exactly what I need. I tried multiple filters and works beautifully.

happy to hear it @ermingut!!

it would be awesome if you could share the use case for which you’re using this in [Show and tell - Tulip Community](https://community.tulip.co/c/show-and-tell/9).
