API Docs > **[List Registration Questions - Webinars - Zoom API - API Reference](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrantsquestionsget)** > > Scheduling a Webinar with registration requires your registrants to complete a brief form with fields and questions before they can receive the link to ... When i make a request to add a custom question using {“custom\_questions”:[{“title”:“test field”,“type”:“single\_radio”,“required”:true,“answers”:[“Yes”]}]} I ge the following error {“code”:300,“message”:“Validation Failed.”,“errors”:[{“field”:“custom\_questions[0].answers”,“message”:“Invalid field.”}]}stdClass Object ( [code] =\> 300 [message] =\> Validation Failed. [errors] =\> Array ( [0] =\> stdClass Object ( [field] =\> custom\_questions[0].answers [message] =\> Invalid field. ) ) ) I have noticed if I amend the answers value to contain 2 values instead of 1 it works. {“custom\_questions”:[{“title”:“test field”,“type”:“single\_radio”,“required”:true,“answers”:[“Yes”,“No”]}]} In the API documentation, the example shows 1 answer in the json query. If you login to zoom and manually edit the webinar you can also set 1 answer. Does anyone know the reason I cannot set 1 answer through the API? Thanks ---

Hey @ian1 Thanks for posting on the Zoom Devforum! I am still learning, but I will try my best to help answer your question. 🙂 Checkout this related thread that may have the answer you are looking for: > [@Add webinar registrant (with invalid webinar ID)](https://devforum.zoom.us/t/-/6284): > > Description/Error I’m seeing successful responses, HTTP status code 201 created, when calling the “add webinar registrant” endpoint with a non-existent webinar id. The documentation for responses, indicates we should receive HTTP status code 300 for an invalid webinar ID, or HTTP status code 404 not found (not sure which of these is right, but either of these would be better the current behaviour of a success result, and sending an email to registrant they have been added). Which Endpoint/s? … If this thread did not help, please let us know by replying back here and someone from the Developer Relations team will get back to you shortly. Thanks, DeveloperBot ---
