Working with lists / arrays
Standard approaches to working with lists / arraysCopy
Accessing data in arraysCopy
As described in Mapping data between steps you can directly access list data returned by workflow steps by using jsonpaths such as $.steps.hubspot-1.results[0].properties.email
The [0] being used here tells us that we are digging into the first object in the 'results' array.
This is the standard method of directly sending data from one system to another, if no transformation. filtering etc. is required
Looping through arraysCopy
Probably the most common action taken with lists is to use the loop connector to loop through the entire array and take an action on each item:
For each item in the array you can carry out any operation you need using core / helpers connectors
A common things to do here is to use the Data storage 'append to list' operation to build a new modified list, before using data storage 'get value' outside the loop, in order to retrieve the final modified array and send it on to another service.
Manipulating arrays (filtering, concatenating, extracting items etc.)Copy
Our List Helpers connector can be used for multiple list manipulation tasks including:
Adding items
Filtering to include / exclude items
Sorting
Plucking properties e.g. email addresses from each object
Remove duplicates
Count items
Please see our Academy List Helpers course for an interactive lab which can help you get started on working with our list helpers.
Building listsCopy
When building lists, List Helpers operations such as 'add item to list' and 'add multiple items to list' may meet your requirements.
However, it will sometimes be appropriate to make use of the Data Storage 'Append to list' operation.
This is because the List Helpers operations do not have data storage capacity.
The following example shows looping through an array of contacts in order to perform a minor transformation, create a new contact object and add it to a list that can be retrieved once complete:
