Authorizing request POST DirectMessage

[pot_confiture]

Hello,

I want to make request to the Twitter api to send direct messages, i’m having trouble since i have a error 401. I have severals questions :

• Does POST requests to send dm requires “Application-only authentication” and therefore this process with the bearer token : https://developer.twitter.com/en/docs/basics/authentication/overview/application-only ? Or does it requires this process much more complicated : https://developer.twitter.com/en/docs/basics/authentication/guides/authorizing-a-request ?

• Do i need to send more than one request to post a dm ?

Thank you very much

You have to use three-legged authentication with a user context in order to send Direct Messages. Application-only authentication has no user context, so it would not be possible to identify which user was sending a message to which other user.

Thank you. Three-legged authentification isn’t convenient for me as my service doesn’t include a HCI.

what i want to do is :

• A user wants to be contacted, he types his screen_name.
• The web service send the screen_name to me.
• I receive the screen_name, and post a direct message to him (if he doesn’t have the option “receive dm from anyone” activated he won’t get the message).

I am a little lost, i know it’s a lot but i’d appreciate it if someone could help me
