# Why does a Hevy activity pull return 404?

**Some providers only support a subset of data types.** A 404 with `this connection does not support the requested data type` is the expected response for an unsupported type.

For **Hevy**, read coverage is:

* body measurements
* athlete profile
* planned workouts (write side)

Completed workout sessions (sets, reps, weight) are **not** exposed through their API and are not available under any other data type. Gaps like this can be flagged to product, but there is no workaround until the provider exposes the data.
