Hello @SunithaShivananjaiah,

Generating tokens for RESTler is done through a custom script or program you provide, and the token can be passed to RESTler in several ways, as described in SettingsFile.md (see the 'Authentication' section). Below is an example Python script and settings which you can copy-paste into engine_settings.json to configure RESTler to use the auth token. In the data settings dictionary, specify any parameters you'd like to pass into the script (such as the client ID, and any additional settings to retrieve the secret).

  "authentication": {
    "token": {
      "module": {
        "file": "/path/to/auth.py",
        "function": "acquire_token",
        "data": {
          "client_id": "<GUID>",
          ...
        }
      },
      "token_refresh_interval": 300
    },

def acquire_token(data, log):
    token = gen_token(data)  # implementation to retrieve the token
    token_lines = [
        "{'user1':{}}",
        f"Authorization: {token}"
    ]
    return "\n".join(token_lines)

Thanks,

Marina

Hi @marina-p,

Thank you for your input,
I had updated authentication info in engine-settings.json file as below and data file as below but am getting exception - "Cannot deserialize mutations dictionary: An exception occurred during deserialization: Newtonsoft.Json.JsonSerializationException: Could not find member"

Code snipet:
engine.settings.json
{
"per_resource_settings": {},
"max_combinations": 20,

"authentication": {
  "token": {
    "module": {
      "file": "C:/restler_bin/restler/demo_server_config/acquire_token.py",
      "function": "acquire_token",
      "data": {
        "client_id": "client_id",
        "client_secret": "client_secret"
        
      }
    },
    "token_refresh_interval": 600
  }

}
}
