Hi I’m having a problem when posting a tweet with line breaks inside.

The response sends error code 32 : could not authenticate you.
I am using Postman and my request is POST https://api.twitter.com/1.1/statuses/update.json?status=This is my tweet%0Aon two lines
The same happened with %20 instead of white spaces.

I tried using \n and \r\n in the status parameter, it just posted “This is my tweet\non two lines”, so my authentication is correct, but the result is unexpected.

I don’t know if it’s a bug, if I am not allowed to add line breaks in tweets, or if I am just doing things wrong :man_shrugging:… Still, the response is a bit strange, as I know that my credentials are ok…

This depends entirely on how the call is made - in what language / library. If the code incorrectly % encodes the request url given the tweet text, you will get this error, because the OAuth signature won’t match.

thanks for answering :slight_smile:
I am using Postman which is a software to make calls.
It simplifies things like authentication and parameters.

I don’t think it changes my parameters in any way, so maybe I should use another line break symbol ? (\n didn’t work, I don’t know any other)

There’s probably a way in postman you can do this - you may have to manually do something to specify an escape character. I don’t like using it for stuff like this because errors like the one you got are too easy to make.

I’d suggest trying calls in twurl GitHub - twitter/twurl: OAuth-enabled curl for the Twitter API or even better, a twitter specific library like GitHub - geduldig/TwitterAPI: Minimal python wrapper for Twitter's REST and Streaming APIs

Thanks, I solved my problem with Postman, I was using parameters, when i should be using x-www-form-urlencoded body.
In my settings, I set “Trim keys and values in request body” to ‘On’

I am developing a Flutter app, and it doesn’t provide a twitter specific library, I’m going to see if the library I am using provides a way to do this

Ah, i didn’t know about flutter, but it looks like there’s already a library for twitter API calls? twitter | Dart Package i’d try to use that or another OAuth library to manage calls.
