How to make Twitter API call through curl in unix

Question

I would like to pull the data from Twitter REST API. I have created the consumer key, secret and Access token, secret. I have tried with "Test OAuth", it generates a CURL command but if I change any one parameter then it is giving the below error. Message: {"errors":[{"code":32,"message":"Could not authenticate you."}]}

Now I would like to call the twitter API using CURL in shell script for different screenNames.

I want a sample command some thing like mentioned below

curl --get 'https://api.twitter.com/1.1/statuses/user_timeline.json' --data 'count=2&screen_name=aswin' APIKEY:"xxxxxx",Acesstoken:"yyyyyyyy"

Thanks in advance.

Regards, Aswin

Answer 1

I found the answer.

curl --get 'https://api.twitter.com/1.1/statuses/user_timeline.json' \
     --data 'count=2&screen_name=twitterapi' \
     --header 'Authorization: OAuth oauth_consumer_key="AAAAAAAAAAAAAAAAAAAA", oauth_nonce="BBBBBBBBBBBBBBBBBBBBBBB", oauth_signature="CCCCCCCCCCCCCCCCCCCCCCCCCCC", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1471672391", oauth_token="DDDDDDDDDDDDDDDDDDDDDDDDDDDDDD", oauth_version="1.0"'

Answer 2

Since your specific query doesn't require a user context you can use Application only authentication to make this request. The bearer token won't change per request so it should allow you to keep using curl.

n.b. it won't work for all endpoints, but should for the case you listed.
