Tools Details

Tool: createCollection

Creates a collection using the https://schema.postman.com/collection/json/v2.1.0/draft-07/docs/index.html.

Note:

If you do not include the `workspace` query parameter, the system creates the collection in the oldest personal Internal workspace you own.

---

Tool: createCollectionRequest

Creates a request in a collection. For a complete list of properties, refer to the Request entry in the https://schema.postman.com/collection/json/v2.1.0/draft-07/docs/index.html.

Note:

It is recommended that you pass the `name` property in the request body. If you do not, the system uses a null value. As a result, this creates a request with a blank name.

---

Tool: createCollectionResponse

Creates a request response in a collection. For a complete list of request body properties, refer to the Response entry in the https://schema.postman.com/collection/json/v2.1.0/draft-07/docs/index.html.

Note:

It is recommended that you pass the `name` property in the request body. If you do not, the system uses a null value. As a result, this creates a response with a blank name.

---

Tool: createEnvironment

Creates an environment.

Note:

• The request body size cannot exceed the maximum allowed size of 30MB.
• If you receive an HTTP `411 Length Required` error response, manually pass the `Content-Length` header and its value in the request header.
• If you do not include the `workspace` query parameter, the system creates the environment in the oldest personal Internal workspace you own. Parameters|Type|Description -|-|- workspace|string|The workspace's ID. environment|object optional|Information about the environment.

---

Tool: createMock

Creates a mock server in a collection.

• Pass the collection UID (ownerId-collectionId), not the bare collection ID.
• If you only have a `collectionId`, resolve the UID first:
  1. Prefer GET `/collections/{collectionId}` and read `uid`, or
  2. Construct `{ownerId}-{collectionId}` using ownerId from GET `/me`:
  • For team-owned collections: `ownerId = me.teamId`
  • For personal collections: `ownerId = me.user.id`
• Use the `workspace` query to place the mock in a specific workspace. Prefer explicit workspace scoping. Parameters|Type|Description -|-|- workspace|string|The workspace's ID. mock|object optional|

---

Tool: createSpec

Creates an API specification in Postman's https://learning.postman.com/docs/design-apis/specifications/overview/. Specifications can be single or multi-file.

Note:

• Postman supports OpenAPI (2.0, 3.0, and 3.1), AsyncAPI (2.0 and 3.0), protobuf (2 and 3), GraphQL, and Smithy specifications.
• If the file path contains a `/` (forward slash) character, then a folder is created. For example, if the path is the `components/schemas.json` value, then a `components` folder is created with the `schemas.json` file inside.
• Multi-file specifications can only have one root file.
• Files cannot exceed a maximum of 12 MB in size. Parameters|Type|Description -|-|- files|array|A list of the specification's files and their contents. name|string|The specification's name. type|string|The type of API specification. workspaceId|string|The workspace's ID.

---

Tool: createSpecFile

Creates a file for an OpenAPI or a protobuf 2 or 3 specification.

Note:

• If the file path contains a `/` (forward slash) character, then a folder is created. For example, if the path is the `components/schemas.json` value, then a `components` folder is created with the `schemas.json` file inside.
• Creating a spec file assigns it the `DEFAULT` file type.
• Multi-file specifications can only have one root file.
• Files cannot exceed a maximum of 10 MB in size. Parameters|Type|Description -|-|- content|string|The file's stringified contents. path|string|The file's path. Accepts JSON or YAML files. specId|string|The spec's ID.

---

Tool: createWorkspace

Creates a new https://learning.postman.com/docs/collaborating-in-postman/using-workspaces/creating-workspaces/.

Note:

• This endpoint returns a 403 `Forbidden` response if the user does not have permission to create workspaces. https://learning.postman.com/docs/collaborating-in-postman/roles-and-permissions/#team-roles can configure workspace permissions to restrict users and/or user groups from creating workspaces or require approvals for the creation of team workspaces.
• Private and https://learning.postman.com/docs/collaborating-in-postman/using-workspaces/partner-workspaces/ are available on Postman https://www.postman.com/pricing.
• There are rate limits when publishing public workspaces.
• Public team workspace names must be unique.
• The `teamId` property must be passed in the request body if https://learning.postman.com/docs/administration/onboarding-checklist is enabled. Parameters|Type|Description -|-|- workspace|object optional|Information about the workspace.

Tool: getCollection

Get information about a collection. By default this tool returns the lightweight collection map (metadata + recursive itemRefs). Use the model parameter to opt in to Postman's full API responses:

Parameters|Type|Description -|-|- collectionId|string|The collection ID must be in the form <OWNER_ID>- (e.g. ***-33823532ab9e41c9b6fd12d0fd459b8b). access_key|string optional|A collection's read-only access key. Using this query parameter does not require an API key to call the endpoint. model|string optional|Optional response shape override. Omit to receive the lightweight collection map. Set to minimal for the Postman minimal model or full for the complete collection payload.
