Hi @marksbren What method are you using to create the POST request? If with code, can you share the code so we can take a look?
I like to use the Advanced Rest Client extension for Chrome to test things out… here’s how you would use it to generate a POST request for digitalWrite() with the Tinker API/Application.
Setup:
The Response:
There are many ways to Setup the request, you can form xml encode or send as JSON, put the parameters in one long string like I did, or click the Form button and under each Key/Value pair in nice little boxes.
When you need to use GET requests it’s easy to change the setup as well. Not to mention you can save your requests and reuse them later if you don’t want to have to keep typing your ID and access token in.
