Fetching inbox lead message field and triggering automation on Matter status change in Clio Grow API

Hi everyone,

I’m currently building an automation using Clio Grow + Zapier.

My goal is:
Whenever a new lead comes into the Clio Grow Inbox, I want to trigger a Zap and fetch that particular lead’s details.

Firstly, I followed the Clio Grow API documentation:
https://docs.developers.clio.com/clio-grow/api-reference/

Using the Inbox Leads API endpoints, I’m successfully able to fetch lead information such as:

  • name

  • email

  • phone number

  • state

  • created_at

  • updated_at

Everything is working correctly.

However, I cannot find any way to fetch the actual message field that is entered when the lead is created in the Inbox.

In the documentation, I can see references to fields like from_message, but I cannot find how to retrieve that field from the GET Inbox Leads endpoints.

So my first question is:

Is it possible to fetch the inbox lead message field using the Clio Grow API?
If yes, which endpoint should be used?

Secondly, I tried using the native Clio Zapier app with:
“Action → API Request Beta”

to fetch Inbox Leads directly.

But it gives me this error:

“User is not authorized to access this resource with an explicit deny in an identity-based policy.”

I also tried using Zapier Webhooks, and I received the same 403 Unauthorized error.

The Clio API team suggested that this issue may be related to HTTP version handling and mentioned that  HTTTP/1.1 requests (rather than HTTP/2 ones).

Because of this, I created a custom Zapier app using:

  • Clio Platform Developer Portal app credentials

  • OAuth authentication

  • Zapier Developer Platform

After creating the custom app, the API started working correctly, and now I can successfully fetch Inbox Lead details.

The only missing thing is the message field.

So again:
Is it possible to retrieve the inbox lead message content through the API?

My second question:

I want to trigger an automation whenever the Matter Status changes in Clio Grow CRM.

I’m NOT referring to the default Open/Pending status.

I mean the custom Matter Statuses that we manually create inside Clio Grow CRM.

I checked the native Zapier app and the API documentation, but I couldn’t find:

  • a trigger

  • webhook event

  • or endpoint

for Matter Status changes.

Has anyone implemented this before or found any workaround for triggering automations based on custom Matter Status changes?

Any help would be greatly appreciated. Thanks!

Hi ​@automation_journey 

You may want to try reaching out to Clio Support for help with their API.

Hi and welcome to the Community ​@automation_journey! 😁

I looked at the Clio Grow API documentation and their Get an inbox lead endpoint doesn’t have the message available, only the ID, first_name, last_name, email, phone_number, state, created_at and updated_at values are returned:

The “from_message” seems to only available when adding a lead to the inbox, so it doesn’t look like you’d be able to pull the message using their API. 

That said, they are able to send an email notification to you when a new lead is added to the inbox. So if those email notifications contain the message details you’re after then you could try using an app like Email Parser by Zapier for the Zap trigger. The Zap would then trigger on those email notifications and provide the message text you’re after. You can learn more about how to work with Email Parser here: Trigger Zaps from new parsed emails.

For your second question, the Clio app does have an existing Matter Status Updated trigger available but seems like it only sees the changes for the standard statuses (Open, Pending and Closed) not custom statuses. Only the Clio Manage API has any info on its webhook events and there’s events available for status changes on matters, but again these seem to be limited to Open, Pending and Closed:

So you’d need a different approach with this as well. I saw Clio has some in-house workflow automations available. Perhaps you could set up something on their side that automatically sends a webhook to a Zap, or adds a note containing the custom status, when the status of a matter changes. That way you could use either a Catch Hook (Webhooks by Zapier) or the New Matter Note (Clio) trigger to run a Zap when a custom status is applied. 

Keep us posted on how you get on!
