Integromat's Tools includes several useful modules:
The Basic trigger gives you the possibility to define input bundles
The Compose a string action allows you to simplify mapping
The Text aggregator merges selected bundles into a single bundle using a specified separator
The Numeric aggregator allows to apply aggregate functions (SUM, COUNT, etc.) to received bundles
The Sleep module allows you to pause the flow for up to 300 seconds. NOTE: If you wish to pause the flow for longer periods of time, we suggest to split your scenario into two scenarios - the first scenario would contain the part before the pause, the second scenario would contain the part after it. The first scenario would end up with storing all the necessary information to a Data store together with the current timestamp. The second scenario would periodically check the Data store for records with timestamp older than the intended delay, retrieve the records, finalize the processing of the data and remove the records from the Data store.
