Participant Update

To update an existing account, use the same /api/v2/account/set endpoint. The system determines whether to update an account based on the presence of identifying parameters.


  • Matching Mechanism

The API identifies accounts using the following hierarchy:​

  • id: Account internal ExpoPlatform unique identifier.

  • external_id: An external identifier used by third-party systems.

  • Email: Account Email

If multiple identifiers are provided, the system prioritizes them in the order listed above.

By following this order, the API allows (if necessary):

To change visitor's external ID

To change visitor's email
