Update a contact using the maileon contact id and the corresponding checksum. This call updates standard and custom contact fields as well as the external id of the contact (if provided). It is also possible to update the permission of the contact. In case the permission is upgraded to double opt-in or double opt-in plus, a doi process can be triggered by using the corresponding parameters (and the permission is not set directly).


Parameter Default Description
id The maileon contact id
checksum The checksum of the maileon contact id
permission This parameter should only be used if the permission of the contact should be updated. Supported values are 1: none, 2: single opt-in, 3: confirmed opt-in, 4: double opt-in, 5: double opt-in plus, 6: other. Please be aware of the rules specified with parameter triggerdoi
triggerdoi false If provided and true (supported values are true and false) and if the permission is either 1, 2, 3 or 6 the permission will be set directly and NO DOI mail will be sent as it is not required for those permissions. If the permission is set to 4 (doi) or 5 (doi+), a doi process will be triggered for the contact instead of setting the permission to 4 or 5 instantly (again: the permission will not be changed).
src A string intended to describe the source of the contact. If provided, the string will be stored with the doi process
page_key In case where this method was called by a landing page such as a profile update page, this string offers the possibility to keep track of it for use in reports related to doi processes
doimailing This parameter is ignored if triggerdoi is not provided or false. References the doi mailing to be used. If not provided, the default doi mailing will be used
ignore_checksum false If this flag is set to true, the method will ignore the checksum. This flag should only be set when the call is not issued by a customer directly but by a third party application. See FAQ for further information."
