4. SDKs - Cosmo SDK/API
- LikeCoin chain is built on top of cosmos sdk
- Compatible to most cosmos sdk tools and documentations
- E.g. Tendermint / cosmos LCD restful API:
https://cosmos.network/rpc/v0.37.9
- Wallet / other cosmos tools might also work, if chain
parameters are set accordingly e.g. bigdipper
- @Chung will talk about it more in next week

5. LikeCoin button
- An website embedded in iframe, example
- Current two ways to integrate: iframe and js
- More sdk will be developed in the future: php, vue, react,
etc

13. API
- https://api.docs.like.co/
- We use Postman for development and documentation
purpose
- There are public APIs that does not require authentication,
and auth-ed API that uses OAuth 2.0 and JWT auth

14. Public API
- LikeCoin info and statistic, public user profiles, transaction
records, Cosmos LCD, and public LikeCoin button / article
info are accessible via api.like.co
- Many of our current products / SDKs are also built on top
of these

15. Public API - Demo: badges
- We have these little badges for showing LikeCoin
ecosystem real-time statistic
- We will use stat api and display the data with gh-badges
library
- How is it done

16. OAuth API
- We use a OAuth2.0-like auth flow
- We don't have a developer console yet, client id and
secret are generated on request, contact us if you need it
- Sensitive scope like `email`, `like:read` `like:write` are not
granted by default, please contact us if you feel that you
have a very suitable use case for them.

17. OAuth API - Demo
- We will use passport and @matters/passport-likecoin for
our auth flow
- This is a minimal example so we won’t handle the refresh
token part
- Demo

18. Conclusion
- Many of these APIs and SDKs are still under
development, or are in still experimental state
- Comments, suggestions and contributes are welcome!
