I’ve done a lot with APIs in Thunkable and I still have not been able to get a POST command to work. I know it’s possible but I find it confusing and after hours of trial and error, I usually give up. But actually, from the link you posted above, that API looks pretty straightforward. I always get stuck when I have to create a time-stamped authentication string. But that one is just asking for two simple headers. So probably not too bad! See this topic: [Post header - SET HEADERS method](https://community.thunkable.com/t/post-header-set-headers-method/1172691/) And [this post](https://community.thunkable.com/t/post-header-set-headers-method/1172691/9) in particular. --- _[View the full topic](https://community.thunkable.com/t/sentiment-analysis-api-not-working/1176047)._
