If you need a Zapier integration expert to connect two systems (like Filevine → your internal platform) you usually need three pieces: a clear trigger event, a stable API, and a simple data contract. This guide explains what to define before development starts, what Zapier can and cannot do, and how to get an integration from “works on our account” to “usable by customers.”
What you are building (plain English)
Most “Zapier integrations” are one of these:
Private integration (for one account): built inside one Zapier account for one team.
Public Zapier integration: an app that appears in Zapier’s app directory and can be used by anyone.
For a public integration, you are not just wiring two tools together.
You are defining Triggers and Actions that any customer can use safely.
Define the trigger first
Your integration needs a clear moment that starts the workflow.
Examples:
“A loan request is submitted”
“A record is updated to Status = Ready”
“A button is clicked (webhook or API call)”
For Filevine-style workflows, common patterns are:
A custom field changes
A project/matter is created or updated
An event is created in the timeline
Define the data contract (the exact fields)
Before development, write down the fields the action must send.
Typical minimum set:
Client first name
Client last name
Client email
Client phone
Matter or project ID
Request amount
Attorney name and email (if needed)
If the source system does not reliably expose a field in the Zapier action list, you may need an API call step or a different trigger strategy.
Authentication and access (what slows projects down)
Most timelines slip because of authentication.
Plan for:
OAuth vs API key
Sandbox environment availability
Rate limits
Permissions per user or per workspace
Public app vs private Zaps: what to expect
A public app takes longer because:
Zapier reviews schema and auth flows
Early users will hit edge cases
You need a short beta period with multiple real customers using it
A good strategy is:
Build the core triggers/actions.
Test with a sandbox or real customer account.
Support a small beta group.
Apply for public listing.
Implementation checklist (copy/paste)
Confirm the source system provides the required trigger.
Confirm the required fields can be pulled in a single step.
Confirm the destination system can create a “request” record via API.
Decide how users will map Filevine projects/matters to destination records.
Decide what happens when fields are missing.
Create a beta plan (at least a few real users).
