When mapping items, you can use functions. The functions available in Integromat are similar to functions in Excel or those in other programming languages. The functions let you perform various changes to items, such as changing a bundle item to upper case, cutting selected text to a required size, converting a date into a different format, and many others. Functions are intended for advanced users.
When writing a new Tweet, you should not exceed Twitter's 140-character limit. If you create a scenario with a Tweet containing more than the allotted amount, the scenario run will end with an error. If you map a text item that can contain more than 140 characters to be the source field for the Tweet, you may want to use the
substring() function that will remove the extra characters that are over the limit.
Functions are inserted the same way as mapping items. By clicking a target field, it will open the mapping panel which is divided into several sections. You can switch between them by clicking them. The first section (shown upon opening the panel) displays the items that you can map from other modules. In the other sections, you will find different types of available functions.
To insert a function into a field, click the function name or drag it to the target field.
