PATCH RFC: datatracker.ietf.org/doc/html...
The PUT HTTP verb is used to create or replace the resource under a specific URI completely. In case the resource under a particular URI already exists, it will be completely overwritten by the payload that you send. In case the resource under the particular URI does not exist, the resource will be created.
Practically speaking PUT always almost means replacing an existing resource though because most APIs will not allow the client to choose the URI of a particular resource that does not exist.
In contrast, the PATCH HTTP verb describes what changes should be applied to an existing resource to create a new version. In this case, only individual fields are modified to create a newer and updated version of the resource.
In some sense you could argue that PATCH is less invasive than PUT in the sense that only individual fields are updated whereas with PUT you replace the resource completely with a new state.
In the wild, you will oftentimes find APIs where the HTTP verbs are not properly mapped. I.e. you might find a PUT endpoint that only replaces individual fields of a resource.
What do you think about this video?

Great video. Thanks! My summary:
PUT - Creates or replaces entirely
PATCH - Updates fields
yes, that about sums it up 👍
I've been following up some tutorials from your Chanel, and OMG! The best practices and concise information are amazing! Hope you are doing well, kind of miss you already.
Glad you like them!
This is the explanation I was looking for since a long time… Thanks a lot
Glad to hear that
Very clearly described the difference. Thanks a ton.
Glad it helped
Very clear. Tysm!
Glad it was helpful!
It's so very useful for me, thanks you very much
Glad it helped!
Amazing! My understanding from this video is that PUT is analogous to object-like storage in S3, and also it comes with high security risk of data manipulation
Yes, I noticed times and again that whoever wrote the specification did not really go over them logically and make sure there was no overlap. The explanation here was good. The reality though is staggering as developers who never read the spec "REST-ful", or should I say REST-like code. Of course, I can't blame them - they are constantly assigned 2.5 their possible workload ALL the time. So who has time to read the spec!? The managers just wants them to close the tickets, so the report looks good.
True, but I found that if you know the theory and the spec, you can get things done way faster and have less stress in the long run
nice, thank you very much
Welcome 😊
Thanks!
👍
what if I make a PUT request that only has data for a new street_name and street_number like the PATCH request has? would it act the same way like the PATCH request and only change those two fields OR would it change those two fields + overwrite the other data fields with nothing " " OR would it just give me an error?
It all depends how the developer implement the logic
I am a tad bit confused about following statements:
1. Put can be used to create a resource which doesn't exist
2. While trying to replace a resource which doesn't exist, an error will be thrown.
Can you please clarify the above?
1. PUT overrides whatever resource is specified under the URL with the payload you send. If the resource does not exist, then it will create it. That is how it is specified in the HTTP RFC
2. Patch updates individual fields of a resource, i.e. if the resource does not exist, then there will be an error
dats why i always use patch when updating
