# Merge a fork

POST https://api.postman.com/collections/merge
Content-Type: application/json

**This endpoint is deprecated.**

Merges a forked collection back into its parent collection. You must have the [Editor role](https://learning.postman.com/docs/collaborating-in-postman/roles-and-permissions/#collection-roles) for the collection to merge a fork.


Reference: https://learning.postman.com/api-docs/api-reference/collections/merge-collection-fork

## Authentication

- `x-api-key` header (required)

## Servers

- `https://api.postman.com` (https://api.postman.com, default)
- `https://api.eu.postman.com` (https://api.eu.postman.com)

## Request

### Body (application/json)

- `destination` (string, required) — The destination (parent) collection's unique ID.
- `source` (string, required) — The source collection's unique ID.
- `strategy` (enum, optional, default: updateSourceWithDestination) — The fork's merge strategy: - `deleteSource` — Merge the changes into the parent collection. After the merge process is complete, Postman deletes the fork. You must have Editor access to both the parent and forked collections. - `updateSourceWithDestination` — Merge the changes into the parent collection. Any differences in the parent collection are also made to the fork.
  - Allowed values: `deleteSource`, `updateSourceWithDestination`

## Response

### 200

Successful Response

- `collection` (object, optional)
  - `id` (string, optional) — The source collection's ID.
  - `uid` (string, optional) — The source collection's unique ID.
