API Method: /api/photo/get-replace-token
Pre-authenticate a replacement upload of either a video, a thumbnail for a video or a photo. This allows the client to upload directly to TwentyThree's servers from a web browser.
This method can be used to pre-authenticated uploads to a site without proxying them through your servers and the API. The flow is the same as the one described in detail in the Browser-based uploads section of the API documentation, but in general terms this method will return a token which can be included in a standard HTML form to upload files for replacement.
Parameters
| Parameter | Description |
|---|---|
| return_url | The URL where the user is return after both replacement success and failure. The callback is a GET request when permitted (when the return data is less than 1500 chars) and a POST in all other cases; so your callback handler needs to accept both GET and POST. If return_url is empty or omitted, the request will return a simple HTTP 200 OK mesage. |
| background_return_p | Return to the callback url in the background. If this parameter is set to 1 the replace request will not redirect the client directly back to return_url. Instead, a request is made to return_url from the TwentyThree servers and a plain text document in returned containing status information. This option is design for replacing through clients such as Adobe Flash, where a client-side redirected might not be honoured. (The background callback takes the form of a HTTP GET request with a maximum length of 1500 chars.) |
| photo_id | The photo object to be replaced. |
| valid_minutes | How many minutes should the replace token be valid for. The default is 180 minutes (or 3 hours). The minimum value is 15 minutes and the maximum is 24 hours. |
| max_uploads | How many files can be uploaded using the returned token. The default is 1 upload; the maximum is 100 |
