Hi @patrick1993, I moved your post as anything in the docs category gets every reply and the original emailed to every Wappler user.
Could you please clarify your question a little.
Are you asking where the Wappler documentation is for APIs?
If so, I will firstly say that there are not many as every API is so vastly different to the last that they are difficult to document, also most of them have security tokens which people can not share, but they are spattered around.
Here are some of them https://community.wappler.io/search?q=api%20category%3A28
Common Ones like
Facebook login Using OAuth2 Connector with Facebook
Google API Google OAuth & Photos API Tutorial - Part One: Getting Credentials from Google
Amadeus API How to use the Amadeus API
Honestly use the Wappler search instead of trying to find them by browsing through the categories as there are hundreds of them all over the forum, some full guides, some just small portions where users got stuck.
Once you know how the API components them self work, then its literally off the the API developer documentation to actually get things working like they need it to.
