The following should be considered when working with Field Update Keywords.
In order for the Field Update Keyword Action to work, the "Mercury SMS Site Guest User" will need View and Edit access to the field.
Validation Rules, Workflow Rules, Processes & Triggers will run as usual on the Field Updates. These may prevent the update from occurring, or trigger further actions based on the field being updated.
Invalid response values: If the response is invalid for any reason, the field will not be updated. However, the inbound message will still be linked to the relevant record.
Please note that a Lead, Case or Campaign Member Keyword Action will take priority over a Field Update Keyword Action. It is therefore not recommended to have Field Update Keyword Actions that use the same Keyword as any of the other Keyword Action options.
