Batch update: update a group of people related to an account, order, job, or another object
Historically, interactions in Customer.io have been one-to-one: a person performs an event, triggering an automation; a person gains (or loses) an attribute, triggering an automation. Now, you can associate an individual piece of data from incoming webhook, with a group of people. When you run a batch update, you’ll update attributes for, or send events to, a group of up to 1000 people.
For example, if you support multiple users in a single account, you might send a webhook to Customer.io when the account state changes. Now you can use that webhook to set attributes for, or send events to, a group of people to reflect their parent account status in your workspace.
You can use liquid A syntax that supports variables, letting you personalize messages for your audience. For example, if you want to reference a person's first name, you might use the variable {{customer.first_name}}.
