FieldPulse API Guide for Contractors

One-line verdict: A documented, two-way API for customers, jobs, estimates, and invoices, with webhooks for all three business objects — once FieldPulse Support hands you a key and sets the webhooks up. Openness: 4 / 5 — rated 4 because FieldPulse documents CRUD over HTTP with a named webhook catalog and a published rate limit, held back from 5 by one support-mediated setup gate.

The connection that works

Rung 1 — Direct connection. FieldPulse’s help center describes its API as “a developer interface that lets your other business apps read and write FieldPulse data and trigger actions across tools,” exposing records “such as customers, jobs, estimates, and invoices” as endpoints over HTTP. The method set is the full one — GET (retrieve), POST (create), PUT (update), DELETE (delete) — with JSON responses. The vendor’s own use-case list covers the shop-floor reality: create and update customers from a CRM, collect website leads into FieldPulse, create jobs and assign them to techs from a third-party app, create and update estimates and invoices, send them, and mark an estimate converted once it’s accepted.

Sign-in is a single API key in a header. Getting one is the gate: per the vendor’s Getting Started, “if you don’t have one yet, get in touch with us at support@fieldpulse.com to register and activate your API token.” No OAuth flow is documented, and there’s no settings screen where you mint your own key.

Webhooks: a real catalog, documented by event name — Job Created, Job Custom Status Update, Job Start/End Time Update; Estimate Created and estimate status updates; Invoice Created and invoice status updates — delivered in a JSON envelope, including old/new value variants for changes. Two disciplines: webhook setup “must be facilitated by FieldPulse Support” (same gate as the key), and the catalog we extracted lists no customer or payment events — don’t let anyone quote you a “payment received” FieldPulse webhook.

Rate limit: published — 50 requests per second, with a RateLimit-Reset header when you exceed it. The docs also distinguish a throttling 429 from a monthly-quota 429; the monthly quota amount itself is not stated.

Bridge apps: Zapier is present, and FieldPulse’s help confirms it runs both directions (a FieldPulse event can trigger another app; other apps can create/update FieldPulse records) — Zapier shows customer/contact triggers and Create Job / Create Customer actions (bridge evidence). On Make, only a community-built app was found, which Make doesn’t maintain.

Can automate

• Speed-to-Lead — website leads can be collected into FieldPulse as customers through the API, per the vendor’s own use cases.
• Job flow from your other tools — jobs can be created, assigned to techs, and status-updated from a third-party app; job events fire webhooks back.
• Estimate Follow-Up — estimates can be created, sent, and marked converted through the API, with Estimate Created and status-update webhooks to trigger the chase.
• Invoice work — invoices can be created and status-updated from another system, with Invoice Created hooks; purchase orders and contracts are also documented objects.

Can’t automate

• Payments through the API — UNVERIFIED. Payments appear in FieldPulse’s documentation only as an accounting sync (QuickBooks Online / Xero, both ways). A sync is not a payments endpoint — invoice-chase builds should key off invoice status, not a payment object.
• Self-serve anything — no key without Support, no webhooks without Support. Timelines start with that email.
• A plan claim in either direction — UNVERIFIED. The vendor docs we extracted name no plan tier for API access (“All regions; API key issued by FieldPulse”). Don’t let a pricing round-up tell you a top tier is required — or that it isn’t.
• Endpoint-level verb tables — UNVERIFIED beyond the documented method set and overview use cases; per-object paths weren’t individually extracted in our pass.
• An official Make connection — community app only.

Hidden gate: You can’t get a key from a settings screen — you have to ask FieldPulse Support to hand you one, and Support has to set up your webhooks too. It’s a friendly gate, but it’s a person, not a button.

Build fit — what this platform supports well

• Speed-to-Lead — strong fit: customers and jobs are writable, and lead intake is a vendor-named use case.
• Estimate Follow-Up — strong: estimate creation, sending, conversion, and status webhooks are all documented.
• Invoice Chase / AR — workable via invoice status: invoices are writable and hooked; the chase keys off status because no payments endpoint is verified.
• Review Engine — like every platform here, FieldPulse has no verified reviews API (its NiceJob integration sends review requests — a partner integration, not an API), so the review ask runs on our system triggered by a job-completion signal — a job status webhook supplies it.

What this means for your shop

If you run FieldPulse, this is one of the better connection stories for a growing service shop: the objects a builder actually needs — customers, jobs, estimates, invoices — are all documented, with events on the three that matter. Just start the project with the support email for the key and the webhook setup, and write the quote against invoice status, not a payments API that isn’t in the docs.
