When I tried to obtain an access_token from the DevTest/sandbox environment I received a HTTP 503 response / CMN-211 response instead of the expected access_token and a 200 response for the following request:
POST /restapi/v1.0/oauth/token
HOST: https://platform.devtest.ringcentral.com
HTTP Headers:
- Content-Type: application/x-www-form-urlencoded;charset=UTF-8
- Authorization: Basic <BASE64_ENCODED_API_KEYS>
- Accept: application/json
POST Body:
grant_type=password&username=<RC_USERNAME>&password=<RC_PASSWORD>&extension=<RC_EXTENSION>
NOTE: I did replace the values in tags above with actual values
The response I received was:
{
"errorCode": "MaintenanceMode",
"message": "Service is overloaded, please retry later",
"errors": [
{
"errorCode": "CMN-211",
"message": "Service is overloaded, please retry later"
}
]
}
Is the devtest environment in Maintenance mode, or am I doing something incorrectly?
