Create or update events in Apptoto. Apptoto's auto messages will be sent for the events created if Auto Messages are turned on. Otherwise, be sure to include #auto in the event information in order to tell Apptoto to send the Auto Messages configured for the account.
To update existing events, be sure to provide either an external_id or id, otherwise a new event will be created. For the event properties, this API acts like a patch... meaning that only the events fields you specify will be updated.
However, if you provide a value for the "participants" or "custom_data" field, then provide all of the data. Meaning, it does not act as a patch for custom_data or individual participants.
Please note that participants will not be removed from an event if messages have already started going out to that participant. This "feature" can be turned off, so ask [email protected] if you need it turned off.
Also, please note that we do not support moving an appointment from one calendar to another at this time. If you need this, please contact [email protected] .
