Use this endpoint to submit a single event for a specified customer. The attributes provided in the data object are examples of point_add and checkout events. Refer to the complete list of events for all available actions and their attributes.

Examples of event submission:

• Standard event submission: Submit an event for the customer without any additional identifiers.
• Event submission with an external ID: Include the external_id attribute to link the event with an external identifier of the customer from another system or database.
• Event submission with multiple accounts: Specify multiple accounts by including their IDs in the 'account' attribute. This requires the Points economy module to be enabled.
  Note: if no account is specified, the event will be assigned to the default account.
