• You have a digital experience with your client
• You Should Provide Self Service , Sandboxing, and testable
– No Test no way !
• You work in a competitive world !
– Often your client will test 2 or 3 service providers, it is so easy !
• Your Documentation need to be perfect, Self explainable, self service
– I do not understand , Next ….
• Change is very costly
– You can change Gmail UI or product , not gmail API
• Multiple usage of API
– You do not know how your client will use it => foster innovation , organize Hackathon ! Networking
API is public

16. API as a Product
It’s a transformation
journey
An exciting one !

Everything becomes public

Quality specific tooling and pipeline , Training and skills
Testing , compliance ,
Silo  API is not technical is functional  API is technical also … implementation /
implantability
Integration partner / public / employee are my customer
