Sismo Connect Cheatsheet
This cheatsheet presents all of the types of requests you can make with Sismo Connect. It should be a great companion when developing a Sismo Connect app.
It contains:
How to impersonate Data Sources in your dev Vault when developing a Sismo Connect app
Impersonating Data Sources enables you to be part of Data Groups and generate ZK proofs.
Request a large and diversified request:
Authentication: Data Source ownership
Claims: Data Group membership
Verify them in a back end and access verified data
Visit this section to understand Data Groups and how to create them.
What the Request and Response looks like 👉 https://test-request.sismo.io
SIsmo Connect Response generation (ZK proof generation)
SIsmo Connect Response (with a ZK proof in it)
