# Track Order
After creating Fast Charge orders, use this endpoint to check their status — whether each order is still waiting to be matched or has already been matched.
{% hint style="info" %}
This endpoint requires an API key. See [Authentication](/developers/authentication.md) for how to obtain a key and fund your internal account.
{% endhint %}
## Endpoint
`POST` `https://api.tronsave.io/v0/fast-charge-order-tracking`
**Rate limit:** 1 request per 2 seconds.
## Headers
Name
Type
Description
apikey*
String
TronSave API key associated with your internal account.
## Request body
Name
Type
Description
order_ids
Array
Array of order IDs. A list of order IDs that have been created and need their status checked.
### Request body example
```json
{
"order_ids": [
"673c17a3129f1881382e98e2",
"673c17a3129f1881382e98e3"
]
}
```
## Response
### Success
```json
{
"results": [
{
"order_id": "673c17a3129f1881382e98e2",
"status": "Completed"
},
{
"order_id": "673c17a3129f1881382e98e3",
"status": "Pending"
}
]
}
```
### Errors
This endpoint authenticates with the `apikey` header.
**401 Unauthorized** — the `apikey` header is missing:
```json
{
"error": true,
"message": "TSAS:106 API_KEY_REQUIRED"
}
```
**401 Unauthorized** — the API key is invalid:
```json
{
"error": true,
"message": "TSAS:107 INVALID_API_KEY"
}
```
**400 Bad Request** — a required field is missing or invalid. The message names the offending field:
```json
{
"statusCode": 400,
"code": "FST_ERR_VALIDATION",
"error": "Bad Request",
"message": "body must have required property 'order_ids'"
}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.tronsave.io/developers/api-reference/fast-charge/track-order.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
