Perfex CRM Development · Integrations
Connect Perfex to the systems that hold your money.
A CRM that does not talk to your gateway, your lead sources, or your accounting is a very expensive address book. Integrations fix that — but only if they are built to survive retries, outages, and the 2am webhook nobody was awake for.
Both directions
What Flows In, What Flows Out
Into Perfex
- Leads from Facebook and Instagram lead ads, in real time via signed webhooks
- Payments from gateways, recorded idempotently against the right invoice
- Contacts and customers migrated from a previous CRM or spreadsheets
- Form submissions from your website, mapped to the right fields and owner
Out of Perfex
- Outbound webhooks on lead created, invoice added, payment received, proposal accepted
- Notifications into the channels your team already watches
- Data for reporting, pushed where your analytics actually lives
- Machine-to-machine API tokens for systems that need read access
The detail that matters
Why a Retried Webhook Should Not Cost You Money
Payment gateways retry. It is correct behaviour on their side — if they did not hear a clean acknowledgement, they assume you missed it and send again. An integration that simply inserts a payment row on every delivery will happily record the same $1,450 three times, and somebody discovers it during reconciliation a month later.
The fix is a ledger keyed on the gateway's own transaction ID, claimed before the write and released after it, so concurrent deliveries of the same payment cannot both succeed. That is how our payments bridge works, and it is why the endpoint can be called as carelessly as the internet demands without corrupting your invoices.
The second half is just as important: the write goes through Perfex's own payment model, not around it. Invoice status updates, the activity log records it, and any webhook you have configured fires — exactly as though a human had entered it. An integration that bypasses the core to be fast leaves your CRM telling you lies.
FAQ
Integration Questions, Answered
Anything that exposes an API or can send a webhook — payment gateways, lead sources, accounting tools, messaging platforms, your own internal systems. The stock Perfex API covers customers, leads, projects, tasks, tickets and staff; where it stops, we extend it with a module rather than working around it.
Because gateways retry. If a webhook is delivered twice — network hiccup, timeout, gateway policy — a naive integration records the payment twice and your invoice is now wrong in a way somebody has to unpick by hand. An idempotent endpoint keyed on the transaction ID books it once, no matter how many times it arrives.
They do when the integration writes through Perfex's own models instead of straight into the database. That is the difference between a payment that updates invoice status, writes to the activity log and fires the after-payment hooks, and a row that silently appears in a table while the invoice still reads unpaid.
Yes — outbound webhooks on the events that matter (new lead, invoice created, payment recorded, proposal accepted) so the rest of your stack reacts immediately rather than on a nightly sync nobody trusts.
It should fail safely and recover by itself. Our lead integration pairs real-time webhooks with a scheduled sweep that re-checks the source with a deliberate overlap window, so a delivery the platform dropped still arrives. Failure handling is the part that separates an integration from a demo.
