# Convert WeChat Channels channel ID to finder username

Resolve a publicly visible Channel ID (sph… short ID) into a finder username (v2_…@finder). Needs channel id. Served by TikHub.

Purpose:
- Resolve a publicly visible Channel ID (`sph…` short ID) into a finder username (`v2_…@finder`).
- With the username you can then call `fetch_user_videos`, `fetch_channel_info`, `fetch_user_profile`, etc.
- ⏱️ Due to WeChat server latency, this endpoint responds slowly; please set your client request timeout to 30 seconds — a timeout that is too small may result in being billed without receiving the response.
Parameters:
- channel_id: Channel ID (`sph…` short ID), e.g. `sphi9BjV8GK0Zsl` (People's Daily). Must start with `sph`.
- raw: Optional, default True. True=raw response; False=simplified parsed structure.
Return:
- Resolved finder username plus account nickname and description

Response structure & JSON Path:
`raw=false` (simplified):
- Input echo: `$.data.channel_id`
- Resolved finder username (feed directly into downstream endpoints): `$.data.username`
- Account nickname (search highlight markers stripped): `$.data.nickname`
- Account description: `$.data.desc` (may be null)
- On miss: `$.data.username` is null with an explanation at `$.data.error`
`raw=true` (raw):
- Result groups: `$.data.data[N]` (each group has `type` + `items[]` / `subBoxes[].items[]`)
- Finder username inside account items: `$.data.data[N].items[M].jumpInfo.userName` or `$.data.data[N].items[M].noticeParam.finderUsername`
- Title / description: `$.data.data[N].items[M].title` / `.desc`
- Others: `$.data.query` (query echo), `$.data.continueFlag`, `$.data.offset`
- Mapping: `username` / `nickname` / `desc` of raw=false are extracted from the first `@finder` account item in `data[].item

## Published example

This is the provider tool’s published example. Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection.


```json
{
  "tool_id": "tikhub/wechat-channels-v2-fetch-channel-id-to-username",

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
