  Apllogies I'm just new to payload. I recently had a demo by your team at our office and I'm building an internal tool with Payload atm to check it out!. I think though I would likely use the

  Local API

  now reading the docs more

  https://payloadcms.com/docs/local-api/overview

  my main goal is just follow best practice for payload dev. I feel like this is the right way to go about updating a different collection from a afterChange hook?

  
  
  

  Hello. This is a pretty old thread I have a similar desire as the vote things described by Will. My case is when an Asset collection item is updated I want to create a AssetHistory record, stamping the Asset's data at a point in time throughout it's life. The afterChange hook is what I need on the Asset Collection and I understand how to create the afterChange trigger. BUT my question in regard to this subject is do you just straight up make axios/fetch calls to the graphql or REST api to add new records to other collections or is there a fancy payload package or utility to do this?

  You could do this with a field hook or a collection hook. They can be used to update

  other

  collections, not just the current 👍

  import type { FieldHook } from 'payload/types';

  
  
  

  // Field hook type is a generic that takes three arguments:

  
  

  // 1: The document type

  
  

  // 2: The value type

  
  

  // 3: The sibling data type

  
  
  

  type ExampleFieldHook = FieldHook<ExampleDocumentType, string, SiblingDataType>;

  
  
  

  const exampleFieldHook: ExampleFieldHook = (args) => {

  
  

  const {

  
  

  value, // Typed as

  string

  as shown above

  
  

  data, // Typed as a Partial of your ExampleDocumentType

  
  

  siblingData, // Typed as a Partial of SiblingDataType

  
  

  originalDoc, // Typed as ExampleDocumentType

  
  

  operation,

  
  

  req,

  
  

  } = args;

  
  
  

  // Do something here...

  
  
  

  return value; // should return a string as typed above, undefined, or null

  
  

  }

  
  
  

  I'm thinking Sibling Data is what I need to use here:

  
  
  

  I have a collection called 'Votes' where a user will vote on another location called 'Locations'. Each Vote will have a locationId and UserId. Would it be possible to update a total tally of votes in the related location collection after a vote document is created using a Hook? I'm not qutie sure if they're only intended for updating document in the same collection or not.
