Error 403 while connecting to Cloud REST API

The HTTP status code 403 while sending the file for processing to Cloud via POST (or performing any other API call) refers to Access denial. 


All API requests must contain an Authorization header. To get the Authorization header:

  1. Concatenate your Application ID and the Token(login to ABBYY Cloud and go Applications tab in order to find both values) using a colon as a separator, e.g.:
  2. Encode the resulting string using any variant of Base64, e.g. QWxhZGRpbjpPcGVuU2VzYW1l.
  3. Add the authorization method followed by a space in front of the string from step 2, e.g. Basic QWxhZGRpbjpPcGVuU2VzYW1l.

The resulting Authorization header will appear as follows:

Authorization: Basic QWxhZGRpbjpPcGVuU2VzYW1l
Please also see how to set the Authorization in Postman (a tool that can be used to send API calls)
