Hi, did you try using the “Query Parameters” instead of “body”? ---

I’m not sure about your recomendation, but, POST doesn’t accept the query parameters (in the HTTP link), POST only accept the parameters in the body. GET is the way to put the parameters in the HTTP link. If you have any sugestion I would apreciate if you will send me an example. ---

Hi ubaldo, do you know what authentication method is expected? also what do the headers look like in insomnia ? i did some tests with api’s requiring different types of auth methods… in the post below you can see how I passed my parameters. maybe that will give you some ideas > [@Compose a POST request using web component](http://community.thunkable.com/t/compose-a-post-request-using-web-component/42897/12): > > How to pass Auth HTTP POST Request @jared you gave me an idea so i did some tests in 3 different apis i found online and this is what worked for me (my blocks should be self explanatory). Notes: don’t mind the naming conventions I was prototyping and too lazy to keep changing names. Authorization for most apis i came accross was always Basic and you will need to convert your user:passwd to base64 encoding. some apis use apikey:(password is blank) refer to api docs example lets say… ---

Nothing is required header is null. When I did this test with Insomnia the server register the API’s call, but when I did it with Thunkable the server doesn’t register anything (nothing), I was thinking if Thunkable suport HTTP Links, becouse the API’s that I have been used and works are HTTPS. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/6/86c6b6197021121264115f40995ad8b6a935d1b7.png) ---

Sorry mate, I missed out the POST part… Indeed I have been working a lot on GET (finance APIs mainly) and that clouded my mind somewhat. 😐 Btw, I have this unexplained issue with GET before. testing ok on other webpages, but not on thunkable. I inserted a short delay (say 0.1 secs) between the set URL or parameters bock and the GET block. Miraculously it worked… Can’t explain why. No harm trying on your POST call. ---

It’s a nice tip, delay souds logist, could you share me the instruction, and about the time of the delay, regards ---

Use the “wait” block, and put it just before the POST block. (maybe the previous block of setting the body content needs some time to complete, I’m not too sure). As for the time to wait, I usually put in 0.1 Secs. Need some trial and error to get consistent results and balance it against unnecessary delaying the process. ---

Hi, here is the correct way to form de json object. Sometimes the computer emulator doesn’t show the correct response, so try to test your app on your phone. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/1/81181a24b162dd8d42c9e0f8972ad8f50e308f55.png) Test on computer: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/9/998229fb873acde533d5b5ddafc60d7eb24672cc.png) Test on phone: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/3/f32e705ad72b65c056e99f2252bedca1fa5c9541.png) Regards ---
