Currently reports can be updated at the following intervals:
- hourly, including every 1, 3, 6, and 12 hours (Business / Team plans only)
All triggers will use the spreadsheet timezone, which you can view by clicking File > Spreadsheet Settings. For more information on changing your sheet timezone, check https://support.google.com/docs/answer/58515.
Please note that if you change your spreadsheet timezone, you will need to delete and re-add your triggers to run off the updated timezone.
To create an automatic trigger, click the Schedule tab in the top navigation menu in the API Connector sidebar.
Here you can choose specific API request names from the drop-down menu, so different requests can have different triggers. Alternately, you can choose the ‘All’ option to select all of them at once.
Once you’ve chosen which request(s) you’d like to schedule, choose your desired refresh frequency.
Triggers are set within API Connector and then managed by Google, which will execute your requests on a recurring interval. According to Google, the time is slightly randomized — for example, if you set a daily trigger between 2am – 3am, Google will choose a time between 2am and 3am for your trigger. Following that, your trigger time will remain consistent each day, such that exactly 24 hours passes before the trigger fires again. If you want to know the exact time your triggers execute, you can add a timestamp to your request (located under Output Options).
In some cases you may want one request to run before a second request, to ensure that some ID or other value is ready for a subsequent request. This can be done by ordering triggers. There are two methods of ordering triggers:
- If you select an “All” trigger, it will run through every request in the sheet, in the order they’re set in the Requests screen. Requests will run from top to bottom.
- If you select specific requests instead of All, it will run through them in the order they’re set on the Trigger screen. Again, triggers will run from top to bottom.
This means that if two triggers are set to run at the same schedule, the one higher up will run prior to the other. Further, if two triggers are set at different intervals, the one higher up still takes precedence over the other one. For example, if you have one trigger that runs every hour, and then one trigger below that that runs every 12 hours, the hourly trigger will run first during each of the 12 hour intervals that these triggers intersect.
On both the Requests screen and the Trigger screen, triggers can be re-ordered by grabbing their handles and dragging and dropping them to the desired order.
Google doesn’t allow add-ons to run triggers more than once an hour. This is their policy for all add-ons, as detailed in the documentation.
As an alternative, you may be able to use API Connector’s custom IMPORTAPI() function to force more frequent refreshes (check the section on Fast cell-based refresh). Note that IMPORTAPI() is a different feature from scheduling, and will run only when the sheet is open.
Google Apps Script services imposes additional quotas and limits. For example there is a limit of 20,000 URL fetch calls (this includes API calls) per day per user, processes can only run for 6 minutes each hour, and triggers have a total runtime limit of 90 mins a day. If your triggers stop running or get delayed, you are likely running into these limits.
The most common causes of trigger issues are the 6 minutes/execution and 90 minutes/day runtime limits on triggers. These runtimes are shared between all your sheets that use triggers, so if you have many sheets or queries refreshing at the same time, your triggers may instead be skipped or pushed to the next hour or day. This can happen consecutively, such that your triggers don’t run at all.
If you are experiencing issues with your triggers, please try the following tips to resolve them:
- To avoid inadvertently reaching Google’s limits, limit triggers and queries where possible. Reserve hourly refreshes for your most important queries, and don’t run hourly refreshes if you only need daily. Your data may never fully refresh if you implement large numbers of hourly triggers.
- Similarly, be aware that paginated calls each count as one URL fetch request, i.e. if you run a request that paginates through 100 pages, Google will count 100 urlfetches. Large amounts of pagination are also more likely to run into Google’s 6 minutes per execution limits. Consider using append mode rather than re-fetching an entire data set via pagination.
- Remove unecessary triggers. Navigate to https://drive.google.com/drive/my-drive and click Recent to identify files that have updated recently, and check to see if these updates were automatically triggered by any script or add-on (not just API Connector). Remove any unused triggers, as they may be interfering with the triggers you want.
- Limit usage of functions like IMPORTAPI(), IMPORTJSON(), and GOOGLEFINANCE() as they can run urlfetches every minute or two and expend your quota.
- Triggers in the Trash bin will remain active until they are permanently deleted. Therefore, navigate to https://drive.google.com/drive/my-drive and click Trash > Empty Trash to remove them permanently.
- Occasionally, Google deletes or disables triggers without apparent reason or warning. This is a bug that has been reported and acknowledged by Google, e.g. here. (Triggers are stored on Google’s side, so you can determine if you’ve been affected by setting triggers and then looking to check if they’ve been deleted or disabled. You can see all triggers associated with your account here: https://script.google.com/home/triggers).
- Re-opening the add-on automatically re-initiates all triggers. So, if your triggers have stopped running, please open the sheet with trigger refresh issues, and open the API Connector sidebar by selecting Manage Request or Create New API Request from the API Connector menu. This will restore any triggers that have been disabled or deleted by Google.
- Google generally provides higher quotas for users with a G Suite business account. If you are using a standard (free) consumer account, upgrading to G Suite may help.
