You can check the API docs for a specific database by clicking the three dots next to your database name and selecting “View API Docs”.
Next, select the table where you want to apply a filter on and scroll in the documentation until you see the “List rows” section. This sections lists all parameters that can be added to the querystring. Also the filter:
For example: you want to see all the records where the country is Saint Lucia:
https://api.baserow.io/api/database/rows/table/[id of your table]/?user_field_names=true&filter__field_[id of your field]__equal=Saint%20Lucia)
If the filter does not work, it is in my case mostly because I made a typo with the double underscores between filter and the field name or the field name and the actual filter.
Tip: I am not very familiar with Flutterflow, but it is a good practise to use a tool like Postman to test your queries.
I am not sure if I completely understand your question. Do you want to make an API call to search items in an external mobile application through the API?
Thanks for your answer. I’m in a basic level and my English is poor. I will try to understand firt what an API is. I’m very happy with baserow but I try to have a “searching” function on top of the list but I didn’t find it. I read that this function is not available yet.
