Enable API update of patron records to blank out expiry date
Sometimes we want to update a patron record and blank out a date in the expiry date field for a continuing staff member.
The patron API cannot do this - blank values are rejected as invalid JSON e.g.
{"expirationDate": " - - "}
{"expirationDate": ""}
{"expirationDate": "--"}
{"expirationDate": "null"}
All we can do is add a date, and for continuing staff we can only use the maximum possible date of 18 Jan 2038.
Enhance the API to accept a blank value in expiry date.
This idea will be reviewed by the Innovative product team for consideration in planning the upcoming product roadmap.
