I tried posting this question yesterday but now I can't find the post so it looks like it didn't actually get created so I'm trying again.

I've been tasked with creating an interface to our AirTable data using an API developed by Brightvine (Brightvine Data Link).  I can get back all the data using the API interface but I need to be able to pass in the last date the process ran on our end and get only those rows created since the last run date/time.  The BVDL gives me a place to enter URL parameters and I've tried using the "filterByFormula" option but I keep getting an invalid formula error.  The BVDL gives me access to the last run date/time in a couple of different formats when creating a parameter.

Any suggestions will be greatly appreciated.

Thanks,

Ray Porter

 

Try creating your formula in an Airtable formula field first to get the format of the formula right. You will also need a {Created time} field. Then after you have the formula right, move it to filterByFormula.

You will probably want a formula that looks something like this. In your code you will replace the date string with your last run date.

IS_AFTER({Created time}, DATETIME_PARSE("2024-01-01", "YYYY-MM-DD"))

A few notes:

- You can include a time in the formula in addition to the date if you need that precision. Lookup the DATETIME_PARSE() function in the formula field reference for more info. 

- Airtable formulas process date/time fields as GMT, so submit your date/time as GMT not your local time.

- Make sure you url encode the parameters.

- The white space in the formula is not strictly necessary. I just like it to make it more human readable.

Thanks.  After some trial and error, this solution is what I needed.  The Brightvine interface makes our lastrun date/time available to me in a couple of different formats.  Here's the formula that worked:

IS_AFTER({Created Date/Time}, DATETIME_PARSE("[$UTC_LASTRUNTIME(u)]", "YYYY-MM-DD"))

Time zones often trip people up. A few best practices:Always store datetimes in UTC in your database.Convert to local time only when displaying in the UI.When filtering by date, compute start/end of day in UTC or in the user’s timezone — but be consistent on both sides.Example for UTC range in JavaScript.
