API Out-Polling Parameters

There are just two URL encoded parameters for polling messages:

Name	Description	Required?
userId	User name for authentication (same as used for logging into the website). User name and password may be passed as form encoded parameters, or in the HTTP Authorization header in Basic format.	YES
password	Your account password	YES

Merge will respond to each and every HTTP request with one of the following result codes:

Code	Meaning	Action Required
200	OK (normal result)	Parse the results for the outgoing message details as described below.
401	Unauthorized	Check `userId` and `password`.
500	Internal Error	Contact Support

For 200 codes (success) Merge will include JSON response containing some or all of message information as described

Note: The order of the parameters may change so use value/pair matching rather than location mapping.
