Hi everyone,

I try to update a field through a custom API using the PATCH method, but it returns this error

    Hi, Looks like a problem with the value in the If Match.

    Yes, it was just a typing error, but I still get the error. The strange thing is that the Get and Post methods work perfectly. I only have the problem to update the registry, could it be some missing property in the API page?

    Hi, Get and Post don't need If-Match, so I still think it's a problem with this value.

    If your API endpoint contains specific value, try using "*" to see if it solves it.

    Hopefully other experts can give you better advice.

    Thanks
