Hello Everyone,
I have a booking scenario that reserves appointments in my Google calendar, which is linked to callin.io as a voice agent. The issue is that the scenario I developed was functioning correctly with no problems or error messages from callin.io. Then, unexpectedly, when I test my voice agent to schedule an appointment, it states that it cannot find availability for that specific date and time. It's peculiar because it was working perfectly just two minutes prior, repeatedly. I haven't altered or edited anything, so I'm puzzled as to why my scenario has suddenly ceased to function. As I mentioned, there are no error messages from callin.io, nor are there any errors in the scenario's history.
The only other possibility I can consider is perhaps exceeding the usage limits for the month. However, even when I review my current operation usage count, it indicates that I haven't reached the limit yet. Please let me know if there are any other usage limits or settings I should examine.
I'd be interested to know if anyone else has encountered a similar problem and how they managed to resolve it.
Thanks in advance

Hi Marcus, does the scenario run appear on the scenario history? If It does appear as Success it could be that your agent is not using the function or the response webhook is not formatted correctly, you can check the callin.io agent tool calls request on ‘Observe’ ‘Webhook Logs’ there select the one you want, then go to response, if it’s empty it means that your webhook response is not formatted correctly and you callin.io agent cannot read it

Thank you for your input. I have a few answers to your solution and a question. I will try what you have suggested and see if that resolves the issue.
I'm a bit confused because if you suspect my webhook isn't formatted correctly, why did my scenario and Vapi booking agent work previously? My scenario and booking agent on Vapi were functioning correctly, checking availability and booking appointments. Then, it stopped working, but I haven't made any changes to my webhook or scenario between when it was working and now. So, do you still believe it could be an issue with my webhook, even though it worked before without any modifications on my end?
Thanks again for responding and offering advice. I look forward to your reply.
Thanks,
Marcus

It could be a variety of issues. Your agent might not be utilizing the functions, or perhaps it's not providing all the necessary parameters for a function. It's also possible the function isn't available to the agent, or the function itself is missing the webhook URL for the scenario. The webhook response string could be too lengthy, causing a JSON format error, or the prompt for your assistant might not be specific enough.
You can test your agent live by clicking “run once” on the scenario, and then instruct your agent to use the function. This will allow you to see if the scenario is using the modules as you intend.
