Check/verify/validate the credentials stored in ota_property_id and
ota_property_password. If the credentials are invalid return with error
ID 1001. If the connection needs to be enabled from the OTA side first
return with error ID 1002.

On Cloudbeds the hotel will go to the OTA setup by selecting the OTA.
There the user will be prompted to put in the credentials
(ota_property_id and ota_property_password), which are provided by your
OTA. Both ota_property_id and ota_property_password will be retained by
us and passed in every call. Should you not need two identification fields
please let us know and we can set it to only ask for ota_property_id.
In that case, the hotel can self-serve as long as no other property is
already using the same ota_property_id. If the ID is already in use by
another property, our customer support team will verify that the new
connection is allowed before enabling it, to prevent a hotel from entering
someone else's credentials.

Implementation suggestions: ota_property_id should typically be a username
or hotel ID on your OTA. The ota_property_password is typically a
password used by the hotel to access your OTA's extranet or a token
specifically for a channel manager.
