Luckily it’s a built in Bubble format - Here are the steps:
As far as doing it the other way around, I assume you would make choose “Date” when you go to set up the API Return Values - For me, “date” pulls in the right date format to work with Bubble. See screenshot.
Hope this helps.
w.fly thanks very much ! You save me a ton of work !

@w.fly Thank you so much for the updated header trick! It’s perfect and has saved me further headache. 
An update to this very old post – This method has been working faithfully for me for years, however I have noticed that every now and then it “doesn’t work”.
Turns out, it’s due to the way the “Current date/time” function natively works in Bubble. When you load a page, it gives the current date and time… however, if you keep the page open for 5 minutes, the current date/time is still what it was when you loaded the page initially.
This can lead to an issue where this worked… then suddenly “doesn’t work” (“hmm, the data is still stale… what gives!?”).
So, the new, free, 5 minute solution, that has proven rock solid for me is the following:
NEW:
This ensures that no matter how long a page has been opened, every time you fire off another API call, the “current date/time” is absolutely the current date/time, thus ensuring fresh data with every call.
Cheers!
Quick question @w.fly
Is it also possible to add this “(header) date” to an API call from a paid plugin? I am using the Stripe Marketplace Plugin and also having the issue with the data that is not refreshing.
Thanks for the help.
If it’s not in the Bubble API Connector, then I don’t believe so 
See image for where I placed mine.
If you don’t have access to that, I am unsure what you could do… Bubble does caching automatically for you and I really haven’t found a way other than the one above to forcefully break the cache.
You’re God 
All works super-fast and stabile.
Thanks, you probably saved me days of research!
Cheers!
I’m wondering why you can’t just use “Calculate formula > Random string” instead of date?
In my case, the API I was using (Wrike) accepted Date as a header – I don’t believe I could’ve just sent it some random string.
Is this not in the docs? This was the exact problem I was experiencing. I was creating a poor-mans polling utility with a repeat every x with a conditional check. I’d really suggest getting this into the docs if it’s not, I didn’t find it at least. Thanks for the find!
I believe you can
@w.fly God Bless you mate! I’ve spent 3 days figuring out how to update the repeating group with info from API and finally found your thread. I wish I’ve found it earlier!
It worked! No words to thank you for the tip.
Testing with a MySql database, I noticed that the changes made through PHPMyAdmin are reflected almost immediately in the repeater group. Did this happen because every second there is a query request to the database?
Hey @maze ,
We’re you able to find a workaround similar to this, but for the Stripe Marketplace Plugin? I’m having issues trying to figure it out. Seems impossible! Ha
I am sorry I can’t help you with this issue…
Amazing thread, thanks a ton!
Hi @julienallard1 @w.fly @agoo7714 I use postgres and I am unable to add a dummy parameter that is now part of the sql statement. I get a error that this data type does not exist when I try to initialise. Can you please advise how you achieved
Infact I have gone to an extent where I have overkilled the workflow and still the repeating group is not refreshing
Your posts have given me some confidence that it is achievable, please help
I am learning some programming the the forum and developing my app, can you please show an example database connector and workflow to make this work.
Any help will be highly appreciated. Thanks
Hi @w.fly Thanks for giving some hope that there is a solution, I was almost in stress since 2 days as I was unable to get the solution working. Can you also share how your repeating group’s data source is set so I can understand how the workflow’s data source injection will impact the repeating group to refresh
