# POST /pocket.proof.Msg/SubmitProof

`POST /pocket.proof.Msg/SubmitProof`

## Request body

- PocketProofMsgSubmitProof
  - `proof` string, byte
  - `session_header` PocketSessionSessionHeader — SessionHeader is a lightweight header for a session that can be passed around. It is the minimal amount of data required to hydrate & retrieve all data relevant to the session.
    - `application_address` string — The Bech32 address of the application.
    - `service_id` string
    - `session_end_block_height` string, int64 — Note that`session_end_block_height` is a derivative of (`start` + `num_blocks_per_session`) as goverened by onchain params at the time of the session start. It is stored as an additional field to simplofy business logic in case the number of blocks_per_session changes during the session. The height at which this session ended, this is the last block of the session
    - `session_id` string — A unique pseudoranom ID for this session
    - `session_start_block_height` string, int64
  - `supplier_operator_address` string

## Response `200`

A successful response.

- PocketProofMsgSubmitProofResponse
