An account is a company saved in Apollo.

Use the Bulk Update Accounts endpoint to simultaneously update multiple accounts in your team's Apollo account.

This endpoint allows you to update common fields across multiple accounts efficiently, such as account stages, owners, names, and custom fields.

You can update up to 1,000 accounts per request.

Important: Asynchronous processing (async parameter) is only supported when using account_ids to apply the same updates to all accounts. If you use async with account_attributes (individual updates per account), the request fails with a 422 error.
