# Bulk update contacts

> Update up to 100 saved Apollo contacts synchronously.

`bulkUpdateContacts` applies individual changes to as many as 100 contacts.

```ts automations/bulk-update-apollo-contacts.automation.ts theme={null}
import { automation, onHttpRequest } from "automate.ax"
import { bulkUpdateContacts } from "automate.ax/apollo"

export default automation("Update Apollo contacts", () => {
  onHttpRequest({ scope: "automation" })
  bulkUpdateContacts({
    updates: [
      { contact: "ada@example.com", title: "CTO" },
      { contact: { id: "contact-id" }, account: "example.com" },
    ],
  })
})
```

`updates` must contain 1–100 items. Every item requires `contact`, identified by
ID, exact email/name, or `{ id }`, plus at least one of `account`, `email`,
`firstName`, `lastName`, `linkedinUrl`, `organizationName`, `presentAddress`,
`title`, or `customFields`. Optional `account` selects the Apollo binding.

Returns the full updated `ApolloContact[]` in provider order.
