Swyfft Partner API

The Swyfft Partner API lets agencies, raters and CRM platforms quote homeowners (HO) insurance programmatically. A single call rates both Admitted and Excess & Surplus (E&S) carriers for a property address and returns live quotes you can adjust element by element.

What you'll find hereCopy Anchor Link

• API Reference: all 5 operations, grouped into Capabilities, Quote Groups and Status, with request and response schemas, examples and a live API playground.
• SDKs: client libraries for C#, Python and TypeScript, generated by APIMatic, with code samples on every endpoint.
• Context Plugin: brings the Swyfft API and SDKs into AI coding assistants such as Claude Code, Cursor and Codex.

Base URLsCopy Anchor Link

All v2 paths start with /partnerapi/v2.

AuthenticationCopy Anchor Link

Send the API key Swyfft issued you in the X-SwyfftApiKey header:

X-SwyfftApiKey: <your-api-key>

Rater and CRM intermediary platforms (for example QuoteRush) also send their own X-SwyfftIntermediaryKey, which overrides the calling account's channel for that request. Direct agency calls omit it.

To get a key, contact partnerapi@swyfft.com.

Your first quote in four callsCopy Anchor Link

1. Check your key: GET /partnerapi/v2/ping
2. Discover carriers and elements for a state: GET /partnerapi/v2/capabilities/{productLine}/{state}
3. Rate an address: POST /partnerapi/v2/quote-groups returns Admitted and E&S quotes in one group.
4. Adjust coverage: PATCH /partnerapi/v2/quote-groups/{quoteGroupId}/quotes/{quoteId}. Common elements such as YearBuilt and RoofAge carry over to every quote in the group.

You can read the group again at any time with GET /partnerapi/v2/quote-groups/{quoteGroupId}.

RetriesCopy Anchor Link

Create a quote group is get-or-create: repeating the same request for the same agency and address returns the existing group while it still has live quotes. Retry sequentially, never in parallel: overlapping requests for one address can create duplicate groups.
