Stores a base64 data URI on the platform and returns a public URL you can then pass to sendFile. Send this one as POST: a data URI is far too long for a query string.

POST https://api.replier.net/UploadFile
Parameters
Name Type Description
mobile required string
The mobile number the account is registered under, in international format.
Example: 447700900123
password required string
The account password.
Example: YOUR_ACCOUNT_PASSWORD
file required string
The file as a data URI, complete with the data: prefix and the mime type.
Example: data:image/png;base64,iVBORw0KGgoAAAANSUhEUg...
Request test
sends a real request
This calls the live API with whatever you enter, so a send endpoint will deliver a real message. Replace the placeholder credentials with your own.

Samples use POST with a form-encoded body so credentials stay out of the URL. The API reads JSON bodies, form bodies and query strings alike.

Response

On failure, every endpoint answers with HTTP 200 and this envelope, where the string is a code from the error reference:

{
    "success": false,
    "msg": ["0008"]
}
