How Do I Add Preview Field - Twitter Social

[pragati_gaikwad]

I am looking for a preview field to be added to one of my clients. Please let me know how I do it.
Below is the API call which I tried but no luck.
https://ads-api.twitter.com/5/accounts/18ce54d4x5t/tweet/preview?text=hello, world&as_user_id=756201191646691328
Also, I checked the endpoint, where twitter_id is required parameter and hence I have to call one more API - https://ads-api.twitter.com/5/accounts/2h34rt/scoped_timeline to get the twitter id.
Using twitter Id I checked the API but no luck. Here I am receiving an error stating " The credentials are no longer valid. Please, re-authenticate " (For valid user).

Thanks.

First of all, the first API call you mentioned will no longer be available as of 2019-08-20 and we recommend using the new Tweet Previews endpoint instead.

so your request will be something like this:
https://ads-api.twitter.com/5/accounts/18ce54d4x5t/tweet_previews?tweet_ids=1122911801354510336,1102836745790316550&tweet_type=PUBLISHED

Here I am receiving an error stating " The credentials are no longer valid. Please, re-authenticate " (For valid user).

Did you re-authenticate with your App? I believe you can re-generate tokens from https://developer.twitter.com/en/apps (-> Details -> Keys and tokens) if you’re the only user who uses the App (single user access).

P.S.
We recently published Postman collection for the Ads API: https://github.com/twitterdev/postman-twitter-ads-api that has full coverage of all the Ads API endpoints we have at the moment.
