  I believe array fields should be considered fields as any other field type - meaning that you don't post an add or remove event of individual array items - rather you post how the new entire array should look like.

  
  

  
  

  So if for example you have an array from the API Get like this:

  [1,2,3,4]

  and you want to remove

  3

  - you would send a

  patch

  event where you would set your array value to

  [1,2,4]

  . If you want to add

  5

  you would send a patch event with array value:

  [1,2,3,4,5]

  I see, thanks for that! It's pity there's equivalent of $push or $pull so that you could edit pre-populated arrays without processing the objects back into strings on the front end

  Well - in theory, you could extend the api and create your own resolver that does it

  https://payloadcms.com/docs/graphql/extending

  
  
  

  So you could create a GraphQL mutation thats called

  addItemToMyArray(...data)

  and then your resolver takes care of the merging locally.

  
  

  
  

  You can do the same for REST:
