Tumblr API: Blog — Post metrics by blog identifier

What this endpoint does

What you can build with this API method

Review the result and common workflows first, then move to parameters and a working request example.

What this endpoint helps with

The response provides a ready-to-use Blog summary with key counters and metrics in the selected API format.

When to use it

Use “Post metrics by blog identifier” for dashboards, scoring, and recurring reports that need a compact metric snapshot.

Common use cases

Product dashboards

Show core Tumblr metrics without loading and processing an entire collection.

Trend monitoring

Store periodic snapshots and compare metric changes over time.

Object scoring

Use aggregate metrics as inputs for internal rankings and rules.

Available versions

Response version

Both versions solve the same job and accept the same parameters. Use the switch to compare the response structure and choose the version your client expects.

Response version V2

Switch versions on this page to compare response structures while keeping the same documentation URL.

V1 Not available

What stays the same

Authentication, required parameters, and the request shape stay the same across V1 and V2. In practice, you choose the version when you build the endpoint path and when you parse the response.

What changes between versions

The main difference is the response envelope. Use V2 for new integrations and keep V1 only when you need compatibility with an existing client contract.

How to use it

How to call the method

Use the same API key header and the same query parameters for both versions. This documentation shows the shared parameter set first, then version-specific endpoint paths and code snippets.

Input parameters

Shared parameters

Parameter	Required	Type	Example	Description
`blog_identifier`	Yes	`str`	`staff`	Tumblr blog username or host without protocol or path. Pass `staff` or `staff.tumblr.com`, not a full URL. Example: staff.
`post_type`	No	`all \| regular \| photo \| quote \| link \| conversation \| audio \| video \| answer`	`all`	Optional Tumblr post type filter. Use `all` for the default mixed timeline. Examples: all, photo.
`tag`	No	`str \| None`	`tumblr staff`	Optional Tumblr tag filter. Spaces are allowed, slashes and URL fragments are not. Example: tumblr staff.

Version-specific request path

V2

Choose a version when you copy the exact endpoint path, example URL, and code snippet. The parameter list above stays the same.

FAQ

Questions teams ask before implementation

Use these answers to decide whether this API method fits your workflow, versioning choice, and rollout plan.

What data does this Tumblr API method return?

The method performs “Post metrics by blog identifier” for Blog. The compact response example below shows the exact field structure.

Should I choose V1 or V2?

Choose V2 for new integrations because it provides a normalized structure. Use V1 only for compatibility with clients that already consume the platform-native format.

What do I need for the first request?

Create an API key, send it in the request header, and provide the required parameters from the table. The code samples already contain the correct path and request structure.
