UploadFile#

For the UploadFile method, we recommend to use the mediaUrl host from console

The method is designed to upload a file to the cloud storage, which can be sent using the sendFileByUrl method. It also allows you to avoid errors in receiving files from external storages and speed up sending messages, for example, in a mailing script.

An alternative way to send a file by uploading from disk: sendFileByUpload.

It is recommended to use the method when sending messages of the same type:

Using the UploadFile method, upload the required file to the Green-API storage, receive a link to the file in the response.
Use the SendFileByUrl method to send using the received link.

Link lifetime is 15 days.

The maximum file size that can be sent is 100 MB.

The type of file you send and how you send it is determined by the file extension.

Request#

To download a file, you need to make a request to the address:

POST

{{mediaUrl}}/waInstance{{idInstance}}/uploadFile/{{apiTokenInstance}}

See the Before you start section to obtain the mediaUrl, idInstance and apiTokenInstance query parameters.

Request headers#

Parameter	Mandatory	Description
`Content-Type`	Yes	Тhe file type in accordance with the list of MIME types . (If the file type is not in the list, then `GA-Filename` is passed instead of this string)
`GA-Filename`	No	The file name with the extension, if the file is not in the list of MIME types. For example, files as `.go` or `.py`. (If the file type matches the list, the string is not transmitted, only `Content-Type` is used)

If the system cannot determine the file type, it will be sent with the default type (binary file): .bin

Request parameters#

Parameter	Type	Mandatory	Description
`file`	binary	Yes	Upload file

Request body example#

You must specify the file itself as the body of the request.

Response#

Response fields#

Field	Type	Description
`urlFile`	string	Link to uploaded file

How to obtain information about the file upload deadline

To obtain the information about the file upload deadline, you need to retrieve information from the link header

To do this:

Obtain the link to the file
Execute a HEAD request with the obtained link
From the result, retrieve the value of the X-Amz-Expiration field
The obtained value indicates until when the link will be available.

As an example the X-Amz-Expiration field, contains the data expiry-date="Fri, 31 May 2024 00:00:00 GMT". Which denotes that the link is available until 05/31/2024 00:00:00 by GMT time zone.

Response body example#

{
     "urlFile": "https://sw-media-out.storage.yandexcloud.net/1101123456/c1aabd48-c1c2-49b1-8f2d-f575a41777be.jpg"
}
