Lawmatics is a legal CRM, client intake, and marketing automation platform for law firms. This integration exposes contacts, companies, matters, billing (invoices, transactions, expenses, time entries), tasks, documents, events, and marketing data as governed MCP tools, scoped per member by access level.

Update Time Entry (lawmatics_update-time-entry)

Update a time entry in Lawmatics by ID. The API requires exactly one of matterId or contactId on EVERY update — to keep the current association, fetch the entry with get-time-entry and pass its relationships.contactable.id as matterId when that pointer's type is "prospect" or as contactId when it is "contact". Other omitted fields keep their stored values; duration is in hours and the hourly rate is in integer cents. Returns the updated entry including a `relationships` envelope of {id,type} pointers to related records (the matter or contact the time is billed to, the staff and creating users, the billing activity type, and the invoice). WARNING: contact-targeted updates can return a server error AFTER the change was saved — on an upstream error, re-fetch the entry to check before retrying.

Lawmatics Frequently Asked Questions

What does the Update Time Entry tool do?

This page documents the Update Time Entry tool (lawmatics_update-time-entry). Update a time entry in Lawmatics by ID. The API requires exactly one of matterId or contactId on EVERY update, to keep the current association, fetch the entry with get-time-entry and pass its relationships.contactable.id as matterId when that pointer's type is "prospect" or as contactId when it is "contact". Other omitted fields keep their stored values; duration is in hours and the hourly rate is in integer cents. Returns the updated entry including a relationships envelope of {id,type} pointers to related records (the matter or contact the time is billed to, the staff and creating users, the billing activity type, and the invoice). WARNING: contact-targeted updates can return a server error AFTER the change was saved, on an upstream error, re-fetch the entry to check before retrying. It is one of the Lawmatics Time Entries tools, invoked through your firm's Weave MCP connection and available to members whose access level permits it.

What is the Lawmatics integration?

The Lawmatics integration connects your firm's Lawmatics account to Weave. Lawmatics is a legal CRM, client intake, and marketing automation platform for law firms. This integration exposes contacts, companies, matters, billing (invoices, transactions, expenses, time entries), tasks, documents, events, and marketing data as governed MCP tools, scoped per member by access level. It groups 177 tools into 40 categories, exposed through your firm's Weave MCP connection and filtered per member by access level.

How does my firm connect Lawmatics to Weave?

An admin connects Lawmatics once for the whole firm via OAuth. Every member then works through that single connection; there is no per-user Lawmatics login.

Do I need to install or configure anything locally?

No. Weave is fully hosted, so there is nothing to install, run, or maintain on your own machines. An admin connects Lawmatics once from the Weave console through a secure OAuth handshake, and your credentials are encrypted at rest and stay inside Weave's infrastructure. After that, each member simply points their AI assistant at your firm's Weave MCP endpoint, and the tools they are allowed to use appear automatically based on their access level.

Can everyone on my team use every tool?

No. Tools are exposed per member by access level, so each person only sees the Lawmatics tools their role permits.

Are changes made through these tools reversible?

Reads are always safe. Deletes are irreversible: they remove the record from Lawmatics permanently.

How are money amounts represented?

All monetary values (expenses, transactions, invoices, time-entry rates) are integer cents; for example, 50000 means $500.00.
