### Example usage

#### Fetching a project

To fetch an individual project:

    curl -u "username:password" "https://my-swarm-host/api/v9/projects/testproject2?fields=id,description,members,name"

P4 Code Review responds with a project entity:

    HTTP/1.1 200 OK

    {
      "project": {
        "id": "jplugin",
        "description": "A Java plugin for continuous integration.",
        "members": [
          "allison.clayborne",
          "jack.boone",
          "steve.russell"
        ],
        "name": "JPlugin"
      }
    }

Project administrators have access to additional fields (`tests` and `deploy`) when fetching individual projects using this endpoint.

### Example usage

#### Creating a new project

To create a project:

    curl -u "username:password" \
         -X POST \
         -d "name=TestProject 3" \
         -d "description=The third iteration of our test project." \
         -d "members[]=alice" \
         -d "members[]=bob" \
         "https://my-swarm-host/api/v9/projects/"

P4 Code Review responds with the new project entity:

    HTTP/1.1 200 OK

    {
      "project": {
        "id": "testproject-3",
        "branches": [ ],
        "defaults": {
          "reviewers": [ ]
        },
        "deleted": false,
        "deploy": {
          "enabled": false,
          "url": null
        },
        "description": "The third iteration of our test project.",
        "emailFlags": [ ],
        "jobview": null,

          "enabled": false,
          "url": null
        },
        "workflow": null
      },
      "readme": "",
      "mode": "add"
    }

#### Creating a private project with branches

Specifying a branch requires using array notation and providing at least two fields (`name` and `paths`) for each branch you wish to create. Creating more than one branch involves incrementing the `branches[0]` specifier for each branch - an example of this accompanies the PATCH endpoint documentation.

Projects are public by default. To mark a project as private, set the private parameter to true.

    curl -u "username:password" \
         -X POST \
         -d "name=TestProject 4" \
         -d "description=The 4th iteration of our test project." \
         -d "private=true" \
         -d "members[]=bob" \
         -d "branches[0][name]=Branch One" \
         -d "branches[0][paths][]=//depot/main/TestProject/..." \
         "https://my-swarm-host/api/v9/projects"

P4 Code Review responds with the new project entity:

### Example usage

#### Editing a project

To edit a project:

It is safe to edit a project without specifying branches, but the instructions for adding branches contain important information for modifying branch configuration.

    curl -u "username:password" \
         -X PATCH
         -d "description=Witness the power of a fully operational Swarm project." \
         "https://my-swarm-host/api/v9/projects/jam"

#### Editing a project to add a moderated branch and make the project public

Specifying a branch requires using array notation and providing at least two fields (`name` and `paths`) for each branch you wish to create. Creating more than one branch involves incrementing the `branches[0]` specifier for each branch.

If you have existing branches, you must specify all of them in the query to avoid data loss. This operation sets the value of the entire `branches` property to match the provided input.

To change a private project to public, set the private parameter to false.

    curl -u "username:password" \
         -X PATCH \
         -d "private=false" \
         -d "branches[0][name]=Branch One" \
         -d "branches[0][paths][]=//depot/main/TestProject/..." \
         -d "branches[1][name]=Branch Two" \
         -d "branches[1][paths][]=//depot/main/SecondBranch/..." \
         -d "branches[1][moderators][]=bob" \
         -d "branches[1][moderators-groups][]=group1" \

## Delete a Project

### Summary

Delete a Project

DELETE /api/v9/projects/{id}

### Description

Mark a P4 Code Review project as deleted. The project ID and name cannot be reused. If a project has owners set, only the owners can perform this action.

- Private projects: when a project is made private, only the project owners, moderators, and members, plus users with super-level privileges in the P4 Server, can see the project, its activity streams, and ongoing reviews. API responses honor these private project restrictions. For more information about private project restrictions, see Private projects.
- Permissions: if a public review contains files that the user does not have permission to view, the review is returned but the restricted files are not displayed.

### Parameters

Parameter | Description | Type | Parameter Type | Required
--- | --- | --- | --- | ---
id | Project ID | string | path | Yes

### Example response

#### Successful Response:

    HTTP/1.1 200 OK

    {
      "id": "testproject"
    }

### Example usage

#### Deleting a project:

Super users, administrators, and owners can delete projects. Members can delete projects that have no owners set.

    curl -u "username:password" -X DELETE "https://my-swarm-host/api/v9/projects/testproject3"

Assuming that the authenticated user has permission, P4 Code Review responds with the id of the deleted project:

    HTTP/1.1 200 OK

    {
      "id": "testproject3"
    }
