Troubleshooting

Should you encounter issues with the Smartsheet API while building an integration using a particular programming language, for example C#, Java, Node.js, Python, or Ruby, keep the following troubleshooting techniques in mind.

Try executing the same API Request using a tool like cURL or Postman. By taking your code out of the equation, you can isolate troubleshooting to the raw Request / Response.

• If you receive a similar error when you execute the Request using cURL or Postman, this suggests an issue with the Request format or contents. Once you have the Request working in cURL or Postman, update your code accordingly.
• If you can execute the Request successfully using cURL or Postman, but not via your code, this suggests that the Request your code is sending is somehow different than what you intend. Compare the (successful) Request from cURL or Postman with the (unsuccessful) Request that your code generates. (See step #2 below.)

Examine the Request that your code is sending (including the HTTP verb, URI, headers, and Request body) and the Response that it's receiving back from Smartsheet (including the HTTP status code, headers, and response body).

• If you've implemented Request / Response logging in your application, inspect the full trace of Request and Response in the log file. Compare the Request that your application is logging with the (successful) Request from cURL or Postman, and update your code to correct any discrepancies.
• Alternatively, you may choose to use a tool like Fiddler or Charles HTTP Proxy to inspect the full trace of Request and Response as it goes across the wire. Compare the Request trace that your application generates with the (successful) Request from cURL or Postman, and update your code to correct any discrepancies.

Check for capitalization errors. NOTE: URL endpoints are all lower case, while object properties and query parameters are camelCase.
