Need something Brex's pre-built connector doesn't cover?

Describe the extra endpoint you need — the Agent researches it via a live web search (or works from docs you hand over) and extends Brex's connector on demand.

Not a block library. Real code.

Legacy automation tools like Zapier, Workato, and Make hand you a fixed library of pre-built steps to drag, drop, and configure around the edges. Knit's Integrations Agent writes real, custom Brex integration code for your exact logic.

Legacy iPaaS

  • Fixed library of pre-built steps — drag, drop, configure around the edges
  • Capped by whatever the vendor's already built
  • AI features bolted on after the fact

Knit Integrations Agent

  • Real, inspectable code for your exact Brex logic
  • Auto-builds a missing Brex connector itself
  • Native LLM connectors built in, not bolted on
Prompt "When a transaction fails in Mercury, sync or log the failure event with Brex."
from knit import Knit

client = Knit(api_key=KNIT_API_KEY)

@client.on("pending-card-transactions")
def creates_a_budget_brex_empower_customers_only(event):
    return client.accounting.creates_a_budget_brex_empower_customers_only(
        integration_id=BREX_INTEGRATION_ID,
        record_id=event["id"],
        fields={
            "source": "Brex",
            "synced_at": event["updated_at"],
        },
        # ...maps the event to a real "Creates a Budget - “Brex Empower” Customers Only" call
    )

Example: illustrative of what the Agent generates from a plain-English prompt — real, inspectable, and yours to edit.

FAQ

Common questions about Brex integrations

Is there a pre-built Brex connector?

Yes — Brex is already live in Knit's Unified API/MCP Servers catalog. This page is about what you can build with it (integrations and automations), not the technical API coverage itself — see the Brex product page for that.

How do I build a custom Brex automation?

Describe what you want above and the Integrations Agent builds it, using Brex's existing connector or researching further API surface as needed.

Which apps does Brex pair well with?

See the popular integrations above — real automations already live, plus more the Agent can build on demand.

How long does a new automation take to build?

Minutes to build a first working version, not weeks — you test it against real Brex data before it goes anywhere near production.
