Updates a contact property's fallback value, the only mutable field. The key and type cannot be changed after creation; create a new property instead.
Paramètres
property_idstringID of the contact property to update.
Corps de la requête
fallback_valueDefault used when a contact has no value for this property and the template does not supply an inline fallback. A string, number, boolean, or RFC 3339 datetime matching the declared type (strings up to 500 characters); a value of another type returns a validation error. Set to null to remove the fallback.
Contenu de la réponse
idID of the property, accepted by every operation that takes a property_id.
keyThe property key, used as the key in contact data and as the attribute in the bird.contact.<key> broadcast template variable. Lowercase letters, digits, and underscores, starting with a letter. Cannot be changed after creation.
typeThe value type every contact must use for a property. Cannot be changed after creation.
datetime values are RFC 3339 timestamps with an explicit offset. Examples include 2024-01-15T09:30:00Z and 2024-01-15T11:30:00+02:00. A bare date or a time with no offset is rejected. The value is normalized to UTC with second precision on write, so 2024-01-15T11:30:00+02:00 is stored and returned as 2024-01-15T09:30:00Z, and any fractional seconds are dropped.
Possible values: string, number, boolean, datetime
fallback_valueDefault used when a contact has no value for this property and the template does not supply an inline fallback. A string, number, boolean, or RFC 3339 datetime matching the declared type (strings up to 500 characters), or null when no fallback is set.
archivedWhether the property is archived. Archived properties disappear from pickers and cannot be used in new template versions. Published templates keep sending. Stored values remain available to read and update. Unarchive the property to restore it.
