# Overriding conversion times

If you want to update old conversions and set historic conversion times, you can do so by passing the unix timestamp of the conversion.

There are three methods to do this currently (we will eventually update our Update Conversions UI to support this too).

## Via Postback
If passing event via postback, you can add the conversion_time parameter to your request, e.g.
```
https://DOMAIN/pb?hit=hit_id_here&tx=some_transaction_id&rev=1.23&conversion_time=1719559745
```
## Via API
If passing conversions via API, you can add the conversionTime parameter to the hits payload. e.g.
```json
{
  "hits": [
    {
      "id": "3xw082xwm09ph2yr18004h",
      "transaction": "some_txid",
      "revenue": "1.23",
      "conversionTime": "1719559750"
    }
  ],
  "disablePostbacks": false
}
```
## Via JS
This will be less common since most JS is executed client-side in real-time

However, you can pass `conversion_time` in your payload, e.g.
```javascript
flux.track("conversion", {
  "tx": "some_transaction_id",
  "rev": "1.23",
  "conversion_time": "1719559745"
})
```
