Upcoming API Changes to Proposal_Open_Contract Call

Raunak

We have noticed a discrepancy in our API.

The response from proposal_open_contract is currently returning Boolean "false" or "true" for the is_sold attribute, where the same response from the "buy" subscription call is returning 1 or 0 for the is_sold attribute.
This should be as per the API documentation https://developers.binary.com/api/#proposal_open_contract either a 1 or 0.

We intend to fix this issue with a release around the 18th of January 2018.

So, with this how do I integrate it to my php design to initiate opening of fresh(new) contract?
Secondly, do you have manual, to check available contract type string field names?
Thank you.
