I need to set a box link to never expire.
The API guide doesn't describe how to do this: https://box-content.readme.io/reference#create-a-shared-link-for-a-folder
I've opened a request on the box communities page, but I'm hoping someone here might know and save me the wait!
I have tried sending both 'NULL' and blank string '' in the field "unshared_at".
NULL just defaulted to the standard date. Blank string failed entirely.
It transpires that PHP was not encoding a null value for 'unshared_at'. If you do successfully send a null, it works just fine.
This works:
{"shared_link": {
"access": "company",
"unshared_at": null
}}
