Hi Vapi team, I’m trying to integrate Vapi with Make.com to trigger outbound calls via API. I’ve followed the documentation and set up everything correctly — including the assistantId, phoneNumberId, headers, and the correct endpoint URL (/calls). However, I keep receiving either a 404 Not Found or 400 Bad Request error when I run the scenario from Make. I’ve confirmed my assistantId and phoneNumberId are correct and active. Can someone from the team help me troubleshoot this or confirm if there's a recent change in the endpoint or payload requirements? I’d really appreciate your support in getting this working. https://cdn.discordapp.com/attachments/1361844239167918200/1361844239700459590/Screenshot_2025-04-16_at_4.21.29_AM.png?ex=68003bc8&is=67feea48&hm=b33029b54faf533d5c728a0f06917c18718a2fdf19217b1b459f7db90572f7f1&

Ensure you’re using the correct endpoint /call, include only assistant Id not both assistant Id and assistant, check that headers and payload are valid, and avoid empty fields from previous modules..

still having the errors even i test the json online validator and it is saying valid json some time i got the error 404 or 400 if i correct the json then it say error 404 if i correct the url as vapi say it will say error 400 if i correct both in the correct it will say error 400 or error 404 im not understanding what is the real issue https://cdn.discordapp.com/attachments/1361844239167918200/1362122510333903108/Screenshot_2025-04-16_at_10.45.38_PM.png?ex=68013ef1&is=67ffed71&hm=91886d0fcb63c2d79251b75553d826aa079004181b895831b34fc976ece97ebc& https://cdn.discordapp.com/attachments/1361844239167918200/1362122510786760714/Screenshot_2025-04-16_at_10.45.56_PM.png?ex=68013ef1&is=67ffed71&hm=8f34e4aa2022e727d589728a37a4730f6f2e2f4c9c5a46920532d4d2dbb17448&
