Describe the problem/error/question
I’m running a workflow that has an HTTP node to an API. Whenever I test the API using Swagger (which is similar to Postman), it works. However, whenever I run the API through the HTTP node, I receive an error stating that I should use the POST method instead of the GET method. However, I’m already using the Post Method.
What is the error message (if any)?
Method not allowed - please check you are using the right HTTP method
Method “GET” not allowed.
Please share your workflow
