Clio's API will happily open a matter. An intake agent should never be the thing that opens one.
Clio publishes a complete, downloadable OpenAPI specification (166 paths including calendar entries, contacts, matters and communications) and its own server list names a Canadian data region alongside the US, EU and Australian ones. The interesting question for a law firm is not what the API permits. It is which of those capabilities an intake agent should be allowed to touch, and the answer is narrower than the API is.
What is Clio, and who runs on it?
Clio is practice management software for law firms: matters, contacts, calendaring, time tracking, billing and document management. It is the dominant system among small and mid-sized firms, and for most of them it is the single system the practice runs from.
Clio's users are also unusually exposed on the phone, because legal intake has a property almost no other vertical shares: the first call is the sale. Someone who has just been in a collision, been served, or been let go is not comparison shopping over several days. They are calling firms in order until somebody answers.
The second property is that the same call carries professional risk. What a caller says during intake can create obligations, and what an intake person says back can create expectations. That combination (high value, high risk, arrives without warning) is why legal is the vertical where the boundaries matter more than the capabilities.
What gap does Clio leave?
It manages the practice and it does not answer the phone, and in legal that gap is measured in retained clients rather than inconvenience. A firm that misses the call does not get a second chance at it, because the caller has already dialled the next firm on the list.
The specific failure in small firms is structural: the people best qualified to handle an intake call are lawyers, and lawyers are in court, in meetings, or with a client. The call arrives at 2:15 on a Tuesday and reaches a machine, and the machine is competing against a firm down the road where someone picked up.
Voicemail is worse here than elsewhere. Someone in the first hours of a legal problem is frequently distressed, and distressed people do not leave voicemails; they hang up and dial again.
None of this is a criticism of Clio. It is practice management software and it manages practices. It has never claimed the phone.
What does Clio's API actually allow?
Creating calendar entries, contacts, matters and communications are all published operations in Clio's OpenAPI specification. The specification also names four regional servers, including a Canadian one. What an intake agent should actually use is a narrower list than that, deliberately.

What that means for your build
The fifth row is the whole point of this page. POST /matters.json exists and works, and an intake agent should not call it. Opening a matter is the step where a firm starts treating an enquiry as a client, and it belongs on the other side of a conflicts check, which is a lawyer's judgment, not an API call. So the sensible build creates the contact, logs the communication, books the consultation into the calendar, and stops. The matter gets opened by a person who has run the check. We would decline to build it the other way.
What it will not do
- Give legal advice, or anything a caller could reasonably hear as legal advice. Whether they have a case, what it is worth, what a deadline means: those route to a lawyer, always.
- Open a matter. The API allows it and we do not, because it belongs after a conflicts check rather than before one.
- Confirm the firm will take the case. Intake gathers; it does not accept.
- Quote fees for anything beyond a published consultation rate.
What does a legal intake call sound like?
A distressed caller, a factual account that matters, and several questions the phone must decline. Doing this well is mostly about what the agent does not say.
An example call: composite, not a recording
Someone calls a personal injury firm two days after a collision. This is the highest-value inbound call the firm receives and it arrives while every lawyer is unavailable.
- Caller
I was rear-ended on Monday and the other guy's insurance has already called me twice. Do I have a case?
- Agent
I'm sorry that happened. I can't tell you whether you have a case - that's for one of the lawyers - but I can get you in front of one quickly and take the details so you're not repeating yourself. Have you given the other insurer a statement yet?
Declining the legal question in the first sentence, then asking the one that is genuinely time-sensitive. - Caller
No, not yet. They want one tomorrow.
- Agent
Then it's worth speaking to someone before that. I have tomorrow at 8:45 or 11:15 with Priya - both are before the end of the day.
Real availability from the calendar. The urgency is real and the agent has recognised why without characterising the legal position. - Caller
8:45. Should I tell them I've got a lawyer?
- Agent
That's exactly the sort of thing to ask Priya at 8:45 rather than me. I've written down that they've asked for a statement tomorrow, so she'll have it in front of her.
The second refusal, without hedging, and the fact captured so the lawyer opens the meeting already knowing the deadline.
A consultation booked for the following morning with the statement deadline captured: as a contact and a calendar entry in Clio, and deliberately not as a matter.
Clio's API will open a matter for anyone who asks it to, which is exactly why an intake agent should only ever create the contact - the matter is the moment a firm starts treating an enquiry as a client, and that belongs on the far side of a conflicts check.
If your intake currently depends on whoever is nearest the phone, the call worth testing is the one that arrives at 2:15 on a Tuesday while everyone is in court.
Start free pilotQuestions law firms ask about Clio
Yes. Clio's OpenAPI specification publishes POST /calendar_entries.json for calendar entries, POST /contacts.json for contacts and POST /communications.json for logging the call, verified from the downloadable spec on August 12, 2026. Worth noting we had this wrong for two days: our first pass could not render Clio's documentation site and recorded it as unverified. The spec had the endpoints the whole time. Re-reading it is what corrected the record.
No, and this is a deliberate refusal rather than a limitation. POST /matters.json exists and works. Opening a matter is the point at which the firm begins treating an enquiry as a client, and it belongs after a conflicts check, which is a lawyer's judgment and not something an intake call should trigger. The agent creates the contact, logs the communication, books the consultation and stops. If a vendor offers you automatic matter creation from phone intake, that is worth a hard question rather than a demo.
Clio's own API specification lists four regional servers (app.clio.com, eu.app.clio.com, ca.app.clio.com and au.app.clio.com) so a Canadian region is available for Clio itself, sourced from the spec rather than from a marketing page. Our side is separate and you should ask about it separately: our data is stored in the United States, stated up front so a reviewer can rule on it in one reading. For a firm with provincial obligations that is a conversation to have explicitly before you sign, not a box to tick after.
By declining early and without hedging, which is a configuration decision made before the line goes live rather than a hope about model behaviour. Whether someone has a case, what it might be worth, what a limitation period means, whether to give a statement: all of it routes to a lawyer. The agent's job on those questions is to capture them accurately so the lawyer opens the consultation already knowing what was asked. A confident-sounding wrong answer is the one failure mode a legal intake line cannot survive.
Hear it decline the question everyone asks first
The free pilot is about fourteen days to a working line with no call limit. Call it and ask whether you have a case; where it stops is the part that matters.
