I have been using the messaging API for a number of years and this is the first time I have seen the below error:
'status' => '404',
'code' => 'RESOURCE-NOT-FOUND',
'message' => 'Invalid resource. Refer to API docs at https://dev.telstra.com',
Tried to search the API Docs and nothing of this error located. I searched the blog and each time I click on a link I get a BAD GATEWAY error message below.
502 Bad Gateway
Appreciate any assistance to fix this issue.
