There are limitations in PUT over PATCH while making updates  Using PUT requires us to specify all attributes even if we want to change only one attribute  But if we use the PATCH method we can update only the fields we need and there is no need to mention all the fields  PATCH does not allow us to modify a value in an array  or remove an attribute or array entry

put  If I want to update my first name  then I send a put request     quot first quot    quot Nazmul quot    quot last quot    quot hasan quot      But here is a problem with using put request  When I want to send put request I have to send all two parameters that is first and last  whereas I only need to update first  so it is mandatory to send them all again with put request  patch  patch request  on the other hand  says  only specify the data which you need to update and it won t be affecting or changing other data  So no need to send  all values again  Do I only need to change first name  Well  It only suffices to specify first in patch request

According to HTTP terms  The PUT request is just-like a database update statement  PUT - is used for modifying existing resource  Previously POSTED   On the other hand the PATCH request is used to update some portion of existing resource   For Example    Customer Details      This is just a example   firstName    James   lastName    Anderson   email    email domain com   phoneNumber     92 1234567890          When we want to update to entire record   we have to use Http PUT verb for that   such as      Customer Details Updated   firstName    James       lastName    Anderson       email    email Updated com   phoneNumber     92 0987654321          On the other hand if we want to update only the portion of the record not the entire record then go for Http PATCH verb  such as         Only Customer firstName and lastName is Updated       firstName    Updated FirstName       lastName    Updated LastName             PUT VS POST   When using PUT request we have to send all parameter such as firstName  lastName  email  phoneNumber Where as In patch request only send the parameters which one we want to update and it won t effecting or changing other data   For more details please visit   https   fullstack-developer academy restful-api-design-post-vs-put-vs-patch

HTTP verbs are probably one of the most cryptic things about the HTTP protocol  They exist  and there are many of them  but why do they exist   Rails seems to want to support many verbs and add some verbs that aren t supported by web browsers natively   Here s an exhaustive list of http verbs  http   annevankesteren nl 2007 10 http-methods  There the HTTP patch from the official RFC  https   datatracker ietf org doc rfc5789  include text 1     The PATCH method requests that a set of changes described in the   request entity be applied to the resource identified by the Request-   URI   The set of changes is represented in a format called a  patch   document  identified by a media type  If the Request-URI does not   point to an existing resource  the server MAY create a new resource    depending on the patch document type  whether it can logically modify   a null resource  and permissions  etc       The difference between the PUT and PATCH requests is reflected in the    way the server processes the enclosed entity to modify the resource   identified by the Request-URI  In a PUT request  the enclosed entity    is considered to be a modified version of the resource stored on the   origin server  and the client is requesting that the stored version be   replaced  With PATCH  however  the enclosed entity contains a set  of   instructions describing how a resource currently residing on the   origin server should be modified to produce a new version  The PATCH    method affects the resource identified by the Request-URI  and it also   MAY have side effects on other resources  i e   new resources may be   created  or existing ones modified  by the application of a PATCH    As far as I know  the PATCH verb is not used as it is in rails applications    As I understand this  the RFC patch verb should be used to send patch instructions like when you do a diff between two files  Instead of sending the whole entity again  you send a patch that could be much smaller than resending the whole entity   Imagine you want to edit a huge file  You edit 3 lines  Instead of sending the file back  you just have to send the diff  On the plus side  sending a patch request could be used to merge files asynchronously  A version control system could potentially use the PATCH verb to update code remotely   One other possible use case is somewhat related to NoSQL databases  it is possible to store documents  Let say we use a JSON structure to send back and forth data from the server to the client  If we wanted to delete a field  we could use a syntax similar to the one in mongodb for  unset  Actually  the method used in mongodb to update documents could be probably used to handle json patches    Taking this example   db products update       sku   unknown           unset    quantity      instock             We could have something like this   PATCH  products sku unknown     unset      quantity        instock            Last  but not least  people can say whatever they want about HTTP verbs  There is only one truth  and the truth is in the RFCs

Here are the difference between POST  PUT and PATCH methods of a HTTP protocol   POST  A HTTP POST method always creates a new resource on the server  Its a non-idempotent request i e  if user hits same requests 2 times it would create another new resource if there is no constraint   http post method is like a INSERT query in SQL which always creates a new record in database   Example  Use POST method to save new user  order etc where backend server decides the resource id for new resource   PUT  In HTTP PUT method the resource is first identified from the URL and if it exists then it is updated otherwise a new resource is created  When the target resource exists it overwrites that resource with a complete new body  That is HTTP PUT method is used to CREATE or UPDATE a resource   http put method is like a MERGE query in SQL which inserts or updates a record depending upon whether the given record exists   PUT request is idempotent i e  hitting the same requests twice would update the existing recording  No new record created   In PUT method the resource id is decided by the client and provided in the request url   Example  Use PUT method to update existing user or order   PATCH  A HTTP PATCH method is used for partial modifications to a resource i e  delta updates   http patch method is like a UPDATE query in SQL which sets or updates selected columns only and not the whole row   Example  You could use PATCH method to update order status   PATCH  api users 40450236 order 10234557  Request Body   status   Delivered

I spent couple of hours with google and found the answer here  PUT       If user can update all or just a portion of the record  use PUT  user controls what gets updated   PUT  users 123 email new email example org   PATCH        If user can only update a partial record  say just an email address  application controls what can be updated   use PATCH   PATCH  users 123  description of changes    Why Patch  PUT method need more bandwidth or handle full resources instead on partial  So PATCH was introduced to reduce the bandwidth   Explanation about PATCH  PATCH is a method that is not safe  nor idempotent  and allows full and partial updates and side-effects on other resources   PATCH is a method which enclosed entity contains a set of instructions describing how a resource currently residing on the origin server should be modified to produce a new version   PATCH  users 123        op    replace    path     email    value    new email example org        Here more information about put and patch

Differences between PUT and PATCH The main difference between PUT and PATCH requests is witnessed in the way the server processes the enclosed entity to update the resource identified by the Request-URI  When making a PUT request  the enclosed entity is viewed as the modified version of the resource saved on the original server  and the client is requesting to replace it  However  with PATCH  the enclosed entity boasts a set of instructions that describe how a resource stored on the original server should be partially modified to create a new version  The second difference is when it comes to idempotency  HTTP PUT is said to be idempotent since it always yields the same results every after making several requests  On the other hand  HTTP PATCH is basically said to be non-idempotent  However  it can be made to be idempotent based on where it is implemented

PUT and PATCH methods are similar in nature  but there is a key difference    PUT - in PUT request  the enclosed entity would be considered as the modified version of a resource which residing on server and it would be replaced by this modified entity   PATCH - in PATCH request  enclosed entity contains the set of instructions that how the entity which residing on server  would be modified to produce a newer version
