# Asynchronous processing

Asynchronous operations are triggered via a `POST` request. The response status in such cases is `202 Accepted`, with a link in the `Content-Location` header. To check the status of the operation, a client can send a request to the location given earlier. An optional `callback_url` can be provided when the asynchronous operation is triggered. If such url is provided, upon completion a HTTP `POST` request is executed containing all information required to identify the specific operation:

Example request:

```json
POST callback_url HTTP/1.1
Content-Type: application/json

{
  "data": {
    "type": resource_strings_async_downloads",
    "id": "xxxxxxxxx",
    "attributes": {
      "location": "https://rest.api.transifex.com/resource_strings_async_downloads/xxxxxxxxx",
      "status": "succeeded"
    }
  }
}
```
