Make sure to change Authorization > Add authorization data to
-- to "Request Headers" (!!) from the default "Request Body / Request URL"

Just a heads up, Twitter now makes you request access and you are not given immediate access.

Very helpful but it took me several tries to get through this. For me the key labeled "screen_name" seems to require being "q" and I had to regenerate all my keys.

In 6.4.4 seems that env vars are not properly passed to OAuth. I have to pass keys directly, then it worked. Is it a bug or sth?

Where is located the values for ConsumerKey, ConsumerSecret, etc ? Do I have to have a developer Twitter account? Thanks

Seem to be getting Auth failures using OAuth1.0 - Getting a 401 Response with
{
"errors": [
{
"code": 32,
"message": "Could not authenticate you."
}
]
}

Also this is not helpful to follow and have to find alternates for those that don't have twitter

Around 3:00 ‘It’s not super easy to read and it’s kinda gross’. Sorry I’m not a 12 year old ... is this what our world has come to? Facebook, social debutantes and the Kardashian? Wonderful I say! Wonderful!!! ‘Like - Over and out ya know’...

Man, This video was great, but she talks too fast! WOW

[MarkUKInsects]

I guess Postman doesn't have the know how to build APIs to use in these demos? Like many, I don't have an account with Google twitter etc.
And slow down!!!!
