We have a module set up that creates a record of SMS sent via Twilio. 

On Twilio's end, whenever the status of the message is updated (e.g. from "Queued" -> "Sending" -> "Sent"), a webhook can be sent to a specified URL. 

Our plan is for Zoho CRM to be the receiving point of this webhook, so that we can then trigger a function from the webhook event, which then updates our CRM record of that SMS.

Bizarrely, I haven't been able to find a way to receive a webhook through Zoho CRM yet. Given that there's an option to do this through Zapier, I figure it already must definitely exist in Zoho CRM. Would love to hear from people who've done this!
