How to Replace Arrays with PATCH in FusionAuth Using application/merge-patch+json
-
The UserData of our users contains an array which is creating a problem for us using PATCH. When PATCH is used to refresh the user it always results in an array append. It appears that one option is to perform a GET request, modify the array, and then execute a PUT request. That's multiple steps, and thus more opportunities for something to go wrong. Can the array values be replaced with a PATCH rather than adding to the array?

Good question. I believe this is due to how we implemented our PATCH calls. If you are making a straight API call, you can change the Content-Type header to application/merge-patch+json which will instead overwrite the existing array with whatever you have provided. That's the most straightforward way to replace array values. There are other methods detailed in the doc below but those involve removing values one by one instead of just overwriting them. The downside here is that I don't believe Client Libraries usually support the merge-patch header.
