Hi,

I'm doing post request from Arduino GSM Shield 2 to Thingworx. Right now i want to remotely create a Thing. I've tried with POSTman, the Request is valid and from Postman I can create Thing. I've posted from shield another request to other page, and i know that shield is configured corectly. But when i do the same request from arduino i get 401 error.

 

My POST (Works in POSTMAN):

 

POST /Thingworx/Resources/EntityServices/Services/CreateThing?appKey=xxxx-xxx-xxxx-xxx-xxx&method=post&x-thingworx-session=true&name=NewThing&thingTemplateName=GenericThing HTTP/1.1
Host: pp-xxxxxxxxxxxx.devportal.ptc.io


Connection: close

Accept: application/json
Content-Type: application/json

 

And Response:


HTTP/1.1 401
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Content-Security-Policy: frame-ancestors 'self'
X-Frame-Options: SAMEORIGIN
Content-Length: 0
Date: Tue, 16 Jul 2019 07:05:21 GMT
Connection: close

 

Can someone tell me wats wrong?

try it without this part: x-thingworx-session=true

You should not need to have to establish a session.

 

Also make sure that 'switch' methods is enabled (I'm not sure if you are using Postman in GET mode or POST mode)

OK, right now the POST:

 

POST /Thingworx/Things/ArduinoSensors/Services/ArduinoService?appKey=xxxxxxx-xxxx-xxxx-xxxx-xxxxx&temp=23.70&humd=55.80 HTTP/1.1
Host: 80
Content-Type: application/json

 

gives me:


HTTP/1.1 400 Bad Request
Date: Wed, 17 Jul 2019 11:19:47 GMT
Server:
Content-Length: 347
Connection: close

I've tried this in postman, and it works. But when i send it from arduino it gives me this error. Dont know why.

Not too sure what is going on, you could try starting out with a simple GET to see if that works, like Thingworx/Things
